Additional Safety Instructions For TheBandsaw

1. Do not operate your bandsaw with dull orbadly worn blades. Dull blades requiremore effort to use and are difficult to con-trol. Inspect blades before each use.

2. Never position fingers or thumbs in linewith the cut, use a push stick. Seriousinjury could occur.

3. Always support round stock in a V-block.

4. Ensure that the machine sits firmly on thefloor before use. Any “wobbles” must becorrected by shimming or blocking beforeoperation.

5. Make sure blade has been properly ten-sioned.

6. Always feed stock evenly and smoothly.Do not force or twist blade while cutting,especially when sawing small radii.

7. This machine is not designed to cut metalor other material except wood.

8. When replacing blades, make sure teethface down towards the table. The force ofthe cut is always down.

9. Do not manually stop or slow blade afterturning the saw off.

10. Habits – good and bad – are hard tobreak. Develop good habits in your shopand safety will become second-nature toyou.

No list of safety guidelines can be complete.Every shop environment is different. Alwaysconsider safety first, as it applies to yourindividual working conditions. Use this andother machinery with caution and respect.Failure to do so could result in serious per-sonal injury, damage to equipment or poorwork results.

Operating this equipment has the potentialto propel debris into the air which can causeeye injury. Always wear safety glasses orgoggles when operating equipment.Everyday glasses or reading glasses onlyhave impact resistant lenses, they are notsafety glasses. Be certain the safety glassesyou wear meet the appropriate standards ofthe American National Standards Institute(ANSI).

Like all power tools, there is danger associ-ated with the Model G1148 15'' Bandsaw.Accidents are frequently caused by lack offamiliarity or failure to pay attention. Usethis tool with respect and caution to lessenthe possibility of operator injury. If normalsafety precautions are overlooked orignored, serious personal injury may occur.

110V Operation

SECTION 2: CIRCUIT REQUIREMENTS

A 15-amp slow-blow fuse or circuit breakershould be used on the 110V circuit this bandsawis connected to. Circuits rated any higher are notadequate to protect the motor from power surges.If you operate this sander on any circuit that isalready close to its capacity, it might blow a fuseor trip a circuit breaker. However, if an unusualload does not exist and a power failure stilloccurs, contact a qualified electrician or our ser-vice department.

Fusing

If you find it necessary to use an extension cordwith the Model G1148, make sure the cord israted Hard Service (grade S) or better. Refer tothe chart in the standard safety instructions todetermine the minimum gauge for the extensioncord. The extension cord must also contain aground wire and plug pin. Always repair orreplace extension cords when they become wornor damaged.

Extension Cords

Grounding

This equipment must be grounded. Verifythat any existing electrical outlet and circuityou intend to plug into is actually grounded.If it is not, it will be necessary to run a sep-arate 12 A.W.G. copper grounding wire fromthe outlet to a known ground. Under no cir-cumstances should the grounding pin fromany three-pronged plug be removed.Serious injury may occur.

In the event of an electrical short, groundingreduces the risk of electric shock by providing apath of least resistance to disperse electric cur-rent. This tool is equipped with a power cord hav-ing an equipment-grounding conductor. SeeFigure 1. The outlet must be properly installedand grounded in accordance with all local codesand ordinances.

The Model G1148 is wired for 110V, single phaseoperation only. The 3⁄4 HP motor will safely draw13 amps at 110V. The motor can also be run on220V where it will draw 6.5 amps, however addi-tional changes may be necessary to make thiswork. See the Wiring Diagram near the back ofthis manual for more information.

FASTENERS

When you are completely satisfied with the con-dition of your shipment, you should inventory itsparts.

The G1148 is a very heavy machine (175 lbs.shipping weight). DO NOT over-exert your-self while unpacking or moving yourmachine – get assistance. In the event thatyour machine must be moved up or down aflight of stairs, be sure that the stairs arecapable of supporting the combined weightof people and the machine. Serious person-al injury may occur.

G1148 15" Bandsaw -9-

Clean Up

The unpainted surfaces are coated with a waxyoil to protect them from corrosion during ship-ment. Remove this protective coating with a sol-vent cleaner or citrus-based degreaser. Avoidchlorine-based solvents as they may damagepainted surfaces should they come in contact.Always follow the usage instructions on the prod-uct you choose for clean up.

Many of the solvents commonly used toclean machinery can be highly flammable,and toxic when inhaled or ingested. Alwayswork in well-ventilated areas far frompotential ignition sources when dealingwith solvents. Use care when disposing ofwaste rags and towels to be sure they donot create fire or environmental hazards.Keep children and animals safely awaywhen cleaning and assembling thismachine.

Do not use gasoline or other petroleum-based solvents to remove this protectivecoating. These products generally have lowflash points which makes them extremelyflammable. A risk of explosion and burningexists if these products are used. Seriouspersonal injury may occur.

Site Considerations

FLOOR LOADYour G1148 Bandsaw represents a large weightload in a small footprint. Most commercial or res-idential shop floors should be sufficient to carrythe weight of the machine. If you have any ques-tion about the floor structure being able to sup-port the weight, contact your local city buildinginspector or a qualified civil engineer or contrac-tor.

WORKING CLEARANCESWorking clearances can be thought of as the dis-tances between machines and obstacles thatallow safe operation of every machine withoutlimitation. Consider existing and anticipatedmachine needs, size of material to be processedthrough each machine, and space for auxiliarystands and/or work tables. Also consider the rel-ative position of each machine to one another forefficient material handling. Be sure to allow your-self sufficient room to safely run your machines inany foreseeable operation.

LIGHTING AND OUTLETSLighting should be bright enough to eliminateshadow and prevent eye strain. Electrical circuitsshould be dedicated or large enough to handlecombined motor amp loads. Outlets should belocated near each machine so power or exten-sion cords are not obstructing high-traffic areas.Be sure to observe local electrical codes for prop-er installation of new lighting, outlets, or circuits.

Make your shop “child safe”. Ensure thatyour workplace is inaccessible to young-sters by closing and locking all entranceswhen you are away. Never allow visitors inyour shop when assembling, adjusting oroperating equipment.

All die-cut metal parts have a sharp edge(called “flashing”) on them after they areformed. This is generally removed at thefactory. Sometimes a bit of flashing mightescape inspection, and the sharp edge maycause cuts or lacerations when handled.Please examine the edges of all die-cutmetal parts and file or sand the edge toremove the flashing before handling.

SECTION 4: ASSEMBLY

Beginning Assembly

Most of your bandsaw has been assembled at thefactory. The remainder of the machine should befairly easy to assemble in your shop. The assem-bly process is organized in steps. Please followthese steps in sequence. We also recommendthat you review the diagrams and parts lists tobecome familiar with all the parts before youbegin.

THE FOLLOWING TOOLS WILL BE NEEDED:

10mm and 12mm wrenches, a set of metricAllen® wrenches, flathead screwdriver, Phillips®

screwdriver, and a 6" or 8" adjustable wrench.

NOTE: Threads on the fasteners are USA stan-dard coarse. The heads, however, are metric.

Stand

All die-cut metal parts have a sharp edge(called “flashing”) on them after they areformed.This is generally removed at the fac-tory. Sometimes a bit of flashing mightescape inspection, and the sharp edge maycause cuts or lacerations when handled.Please examine the edges of all die-cutmetal parts and file or sand the edge toremove the flashing before handling.

Figure 3. Bandsaw stand assembly.

To begin stand assembly, keep all the stand partswithin easy reach. To ease assembly, build thestand upside down on a bench, then place itupright on the floor.

1. Place the 2 short upper braces (#81)upside down on a flat, hard surface. Placethe 2 long upper braces (#83) inside theshort braces so that the carriage bolt holesline up.

2. Secure the legs to each corner formed bythe long and short upper braces. Use 4 car-riage bolts, nuts, and washers for each cor-ner. Finger tighten only.

3. Secure the lower braces between the legs(#85). Since the legs are angled, the lowerbraces are directional, if the holes don’t lineup easily, rotate the lower brace so thatthey do. Don’t try to force it. Tighten secure-ly.

4. Tighten the carriage bolts on the upperbraces.

5. Turn the stand right side up and placewhere the bandsaw will be located.

Motor, Pulley, V-Belt

Bandsaw Unit

This bandsaw is relatively heavy and awkward tohandle. We strongly recommend that you getassistance. The bandsaw unit is also very unsta-ble until it is permanently mounted to the stand.Use care so the bandsaw unit does not tip.

1. Place the bandsaw on the stand with assis-tance and align the four (4) holes in thebase over the four (4) mounting holes in thestand.

2. Loosely secure the bandsaw base to thestand with the four (4) 3/8" - 16 x 3" hexbolts, nuts, and washers provided.

3. Wiggle the bandsaw back and forth on thestand to ensure that the bandsaw stand isseated properly. Ensure that the stand issymmetrical when viewed from the frontand the side. Tighten fasteners securely.

NOTICEEnsure that the Model G1148 is located on aflat, level surface.This will maximize the sta-bility of the machine and ensure that adjust-ments are accurate. For conditions wherepermanent mounting is possible, you mayconsider adding L-brackets at the bottom ofthe stand to enable you to bolt the machineto your shop’s floor. This type of mountingwill minimize vibration and provide a morestable work environment.

2. Insert the 4 carriage bolts through the slots.Use washers on the underside. Finger tight-en the nuts for now.

3. Slip the V-Belt into the grooves of the wheeland motor pulleys. Be sure grooves youchoose are aligned. For general woodwork-ing, use fastest blade speed (i.e. the small-er diameter wheel pulley groove combinedwith the larger diameter motor pulleygroove).

NOTE: For resawing and cutting operations withwider blades, use the slow speed (i.e. the largerdiameter wheel pulley groove combined with thesmaller diameter motor pulley groove). Whenusing the slow speed, do not feed stock too fast.This will cause possible blade breakage, stalling,and extremely poor cuts.

4. Check for proper pulley alignment by plac-ing a plumb line on the outside edge of theupper pulley so that it overlaps the motorpulley. If the line touches both pulleys even-ly, the pulleys are aligned. If the line doesnot touch both pulleys evenly, wiggle themotor until the pulleys come into alignment.If proper alignment is still not attained,loosen the setscrew (#62) on the motor pul-ley and push the pulley in or out to achieveproper alignment. Remember to retightenthe setscrew when finished. See Figure 4 .

1. Align the mounting slots on the motor overthe mounting slots on the base of the band-saw. Be sure that the V-Belt (#28), which isalready installed over the wheel pulley(#30), fits over the motor pulley (#29).

5. Adjust the V-Belt tension by sliding themotor along the slots. Proper tension isachieved when the belt can be deflectedapproximately 3/4" with moderate fingerpressure.

6. Tighten the carriage bolts securely. Re-check belt tension and pulley alignment.

The bandsaw table (#70) secures to the trunnions(#74). The trunnions mount to the table supportbracket (#74) and the table support bracketanchors to the bandsaw unit. The trunnions arepre-mounted to the table. To mount the bandsawtable:

1. Remove the two table bracket mountingbolts (#78) from the bandsaw body. Figure5 shows them removed.

2. There are two alignment pins (#50) thatcross diagonally between the bracketmounting bolts. See Figure 5 . Place thetable bracket on the body over the align-ment pins and secure it to the bandsaw withthe two bolts.

3. Remove the two star knobs (#77), tableinsert (#68), and tapered pin (#71) from thetable.

4. Slip the table past the blade through thetable slot, rotate the table 90°, and set thetable trunnions onto the bracket. Make surethe trunnion bolts (#72) drop through thesupport bracket. See Figure 6 .

5. Secure the table to the support bracket bytightening the two star knobs onto the trun-nion bolts. Remember to position the tableso that the miter slot is to the right of theblade as you face the front of the bandsaw.

6. Place the table insert in the table top andslide the tapered pin so it fits snugly in thehole on the side of the table. Do not useexcessive force or the table will warp.

IMPORTANT: The tapered table pin must be inposition when operating the bandsaw.

Seriousinjury could occur.

Figure 7. Rail attachment points.

Fence and Rails

The saw blade is dangerously sharp. Useextra care when handling the blade, or work-ing near it. Serious injury is possible.

Table Insert

The table insert provides support for materialsbeing cut. It can also be removed for increasedaccess to the lower blade guide.

The insert is supported by a lip formed in thetable casting. No adjustment should be neces-sary beyond placing the insert in the hole in thetable top.

The insert should be flush with the table top wheninserted in position. If the insert sits too high inrelation to the table, inspect the bottom of theinsert and the top of the lip. If burrs or bumpsexist, use a fine flat file or a rotary tool to smooth.If the insert fits too low, use small pieces of mask-ing tape to raise the level of the insert.

The last item to install is the rip fence (assembledaround #114). Notice that the front and backedges of the table have four (4) counterbored andthreaded holes. These holes accept the spacers(#86) and cap screws (#88) that attach the fencerails to the table (#87). See Figure 7 .

1. Secure the fence rails to the table with thefour (4) 1/4" - 20 x 3/4" cap screws and spac-ers provided. For maximum fence travel tothe left of the blade, install the rails so thelonger 10 3/4" segment between the end ofeach rail and the mounting hole is locatedto the left side of the table (facing the frontof the bandsaw).

2. To mount the fence on the left side of theblade, remove the blade from the bandsaw.If you wish to mount the fence to the rightside of the blade, it will be necessary toremove the fence from the rails beforechanging blades.

3. The fence locking handle and knob shouldboth be loose (#107, #91). Slide the fenceonto the fence rails. Ensure that the fenceslides easily. Give the fence rails a shot oflight oil or silicon spray if needed.

NOTE: When the fence is to the left of the blade,the fence must be positioned near the center ofthe table in order to open the lower wheel cover.

Rail Spacers

NOTICEThough the notch in the insert has beenengineered to remain unobstructed at alltable angles, use care to inspect bladeclearance when preparing to make angledcuts. If the blade touches the side of theinsert, refer to the blade guide, and bladetensioning and tracking adjustments in thenext section.

General control and adjustment locations areshown in Figure 8 above and are described inthis section.

A. These two guard locking knobs (#46)secure the upper and lower wheel covers(#24, #25). The covers are only opened tochange a blade or make an adjustment toblade tracking. Blade changing and trackingwill be explained later in this section.

B. This is the toggle switch (#16) that the con-trols the motor. Power is controlled by upand down movement.

C. This handle (#107) and knob (#91) locksthe rip fence in place.

D. These star knobs (#77) are used to lock thetable in position.

E. The miter gauge slides in the milled groovein the table and can be set at 45° left andright. Use the miter gauge for crosscuttingand miter-cutting.

Now, direct your attention to the controls locatedaround the upper part of the saw. See Figure 9 .

F. This knob (#8) is used to control blade ten-sion. Turning clockwise (from the front)increases tension; counter-clockwisedecreases tension.

G. These knobs (#14) control blade trackingby setting the angle of the upper wheel.Note that the knobs have locking nuts inplace.

H. This knob (#93) locks the upper blade guideassembly (assembled around #58) in posi-tion. The upper guide should be adjusted towithin 1/4" of the workpiece for optimumblade support.

Tension/Tracking TRACKING

To adjust tracking, disconnect the bandsaw fromthe power source and adjust the upper and lowerguide assemblies away from the blade. Loosenthe locknuts on the tracking control knobs andturn the knobs clockwise or counter-clockwisewhile turning the upper wheel by hand. The bladeshould track so the body of the blade is centeredon the upper wheel and tire. Turn the wheel byhand at least three full turns to ensure that theblade is tracking in its final position. Retighten thelocknuts. Recheck the tracking. Do not attempt toadjust the tracking on the lower wheel.

DO NOT attempt to assemble, adjust, ormaintain this machine while it is running.Turn off the switch, disconnect the bandsawfrom its power source and wait for all mov-ing parts to come to a complete stop beforeattempting any adjustments or mainte-nance. Failure to do so could result in seri-ous injury.

Proper blade tension and tracking are importantfor optimum bandsaw performance. See Figure 9for bandsaw tension and tracking control loca-tions.

TENSION

Since a wide range of blades will work well in thissaw, proper blade tension ultimately depends onthe type and size of blade you use. Thinnerblades require less tension than wide blades. Toomuch tension will result in blade breakage. Aproperly tensioned blade will track the cutting lineaccurately and the cut will be smoother.

Proper blade tension can best be achieved bydetermining the amount of blade deflection:

1. Ensure that the power is off and the saw isunplugged. Raise the upper guide assem-bly all the way.

2. Press, with moderate pressure, on the faceof the blade with your thumb.

3. Turn the tensioning knob at the top of themachine to change the amount of tension.The blade should flex about 1/4".

If the tension seems correct, make the otheradjustments to the saw (aligning guides, tracking,speed, table and fence) and test run it. If theblade is not cutting properly, the tension may beincorrect and you’ll need to readjust the tension.Remember to reduce the blade tension when thesaw will not be in use, this will help to prevent pre-mature wear or breakage of the blade and/or rub-ber tires.

Adjustment of the upper guides is a two-part pro-cedure, consisting of adjustments to both thesupport bearings and guide blocks. They are asfollows:

Support Bearings - The support bearingsback-up the blade during the sawing opera-tion.To adjust the support bearings, loosen thesetscrews securing the support bearingshafts. Push or pull the shafts so that theupper and lower support bearings are within1/64" behind the blade. Retighten the setscrews.

Guide Blocks - The guide blocks ensure thatthe blade is not pushed too far laterally. Toadjust the guide blocks, loosen the setscrewssecuring the guide block shafts. Adjust evenlyso that the front of the blocks are 1/64" behindthe gullet line (See Figure 13 ) of the blade.Then loosen the guide block securing bolts(#65). Take a short piece of transparent tapeand wrap one thickness of tape around theblade. Move the portion of the blade with thetape so that it is between the guide blocks.Carefully pinch both blocks without disturbingthe blade. Tighten the securing bolts andremove the tape. This provides a clearance ofapproximately .004''.

LOWER GUIDES

Adjustments for the lower guides are identical tothose for the upper guides. Use Figure 11 toidentify the lower guide assembly components.

Make sure there is no deflection of theblade from the straightedge. Measure thedistance between the edge of the mitergauge slot and the straightedge at points Aand B. See Figure 12. Distance A shouldbe approximately equal to distance B.Adjust the table slightly until these dis-tances are equal.

3. Secure the table by re-tightening the trun-nion bolts. Recheck table position to ensurethat unwanted shifting did not occur duringre-tightening.

The table should also be 90° to the back of theblade. If the table is not perpendicular to the backof the blade, shim the table in the desired direc-tion with washers. Remove the trunnion bolts andadd washers between the table and trunnion sothe table tilts in the desired direction. Electricalwashers are very thin and will allow fine adjust-ment.

The bandsaw blade is dangerously sharp.Use extreme caution when working near thesaw blade. Failure to exercise care couldresult in severe injury.

Table Adjustment

The bandsaw table will tilt left 10° and right 45°from horizontal. There is a positive stop adjustingstud (#49) so the table can be re-set perpendicu-lar to the blade after tilting it left or right. SeeFigure 5 . To tilt the table:

1. Loosen the two star knobs below the trun-nions. See Figure 11 for location.

2. Position the table to the desired angle.Refer to the angle gauge on the table sup-port bracket.

3. Tighten the star knobs.

NOTE: If setting table tilt to the left, first tilt thetable to the right, loosen the check nut (#94) onthe positive stop adjusting stud, remove the stud,and then tilt the table to the left.

To adjust the positive stop so the table will be per-pendicular (90°) to the blade:

1. Loosen the two star knobs and the check-nut securing the positive stop adjustingstud.

2. Raise the upper blade guide assembly andplace a 6" machinist’s square or try-squareon the table against the blade. Adjust thepositive stop adjusting stud so that the tablewill stop at a 90° angle to the blade.

3. Secure the star knobs and lock the positiveadjusting stud by tightening the checknut.Ensure that the stud does not turn whiletightening the checknut. Set the anglepointer (#105) to zero.

The table can be shifted side to side to properlyalign the miter slot and the blade:

1. Loosen the 6 trunnion bolts (#75) under-neath the table.

2. Use the largest width blade availableinstalled in the machine. Lay a straightedgealong side the blade and inspect it closelyto make sure it is parallel to the blade.

-18- G1148 15" Bandsaw

Align the fence to the miter slot by first looseningthe two (2) bolts (#109) nearest the operator. Lockthe lower lock knob and measure between thefront edge of the fence (#114) and the front edgeof the miter slot. Compare this to a measurementtaken at the back of the fence and the miter slot.Swing the fence to correct for any difference andmeasure again. When satisfied that both front andback measurements are equal, carefully tightenthe two bolts at the top of the fence.

Fence operation is controlled by the threadedhandle and knob located on the front of the fence.The handle, when screwed tight, locks the fenceto the rear rail. The knob on the lower side of thefence, when screwed tight, locks the fence to thefront rail. To change the fence position, loosen thehandle and knob and slide the fence along therails. To relock the fence always tighten the lowerknob first. This helps the fence to square itself tothe rails. Then lock the top handle to secure thefence.

Fence Adjustment Speed Changes

Loosen the motor mounting bolts and move motoraccordingly to slacken the V-Belt. It should nowbe easy to roll the belt onto the pulleys of choice.There are two pulleys on both the lower bandsawwheel and the motor shaft. The belt should be oneither the inner or outer pulley on both the upperand lower wheels. When the belt is on the pulleysclosest to the motor (inner pulleys) the speed is2600 RPM. When it is on the outer pulleys thespeed is 1750 RPM. Never cross the belt from theinner to the outer pulleys.

Tighten the motor mounting bolts and readjustthe belt tension and check the alignment accord-ing to the instructions provided in theMaintenance Section.

The G1148 has an integral 4'' dust port built-in tothe lower wheel housing. You will achieve bestresults if you connect the machine to a dust col-lection system when you are using the saw. Thishelps to keep the blade and wheels clear of chipsand dust. Plus there is the added benefit of hav-ing less dust put into the air of your shop. Connectyour dust collection hose securely to this portusing hose clamps, and activate the dust collec-tion system at the time you start the bandsaw.

Dust Collection

The Model G1148 15" Bandsaw is a power-ful, professional-quality machine, designedand built to provide outstanding resultswhen used cautiously and with respect. Likeany machine of its type, the Model G1148has some inherent dangers, which, whenused with a lack of care, can result in seri-ous injury or fatality. Please do not attemptto use this machine without familiarizingyourself with the instructions for assembly,adjustment, and safe operation. Failure todo so could result in serious personalinjury, as well as property damage and dam-age to the machine.

Operating this equipment has the potentialfor respiratory damage to occur due to thelevel of airborne dust it produces. Alwayswear a dust mask or respirator when oper-ating equipment.

Bandsaw Blades

SECTION 6: OPERATIONS

The bandsaw is one of the most versatilemachines in the shop. It can cut miters, com-pound angles, simple and complex curves, cir-cles, and a wide variety of irregular shapes. It canalso rip and crosscut, as well as cut a variety ofjoints. The bandsaw will also resaw stock intothinner boards.

There are many adjustment points and compen-sating differences to consider when operating thistype of saw. Therefore, cutting results can besomewhat unpredictable if some or all of the cru-cial adjustments are neglected. Here are a fewsimple things you can do to increase the pre-dictability of your bandsaw’s performance:

1. Always use a sharp, high-quality blade.Although you might save a few dollars ini-tially, buying a cheap blade will give youcheap results. As a rule, spending morenow saves you money later.

2. Use the right blade for the job. Resawingwith a 1/16" blade or doing scrollwork with a1" blade are extreme examples of using thewrong blade for the job.

3. Allow the saw to cut. Don’t force theworkpiece into the blade. When cuttingcurves or irregular shapes, remember thatwhile negotiating a curve, the blade shouldstill be cutting wood. Simply turning theworkpiece will only bind the blade andcould break it.

4. Maintain your bandsaw in top condition.See the following section of this manual formaintenance procedures.

A bandsaw blade is a delicate piece of steel sub-jected to tremendous strain. Be sure you usequality blades of the proper width for the varioustypes of cutting operations. The Grizzly G114815" bandsaw accepts 103" blades.

Always use the widest blade possible for theworkpiece you are cutting. Use narrow bladesonly for sawing small, abrupt curves and for fine,delicate work. Bandsaw blades can be purchasedwelded, set, and sharpened ready-for-use frommost saw shops. We also supply bandsaw bladesin widths of 1/8", 1/4", 3/8", 1/2", and 3/4", for this saw.Please refer to our current catalog for prices andordering information.

Always select and use good-quality saw bladesand choose the right blade for the job. Poor qual-ity blades and improper use are often the causeof premature blade failure.

Many conditions can lead to breakage. Bladebreakage is, in some cases, unavoidable, since itis the natural result of the peculiar stresses thatbandsaw blades are subjected to. Blade break-age is also due to avoidable causes. Avoidablebreakage is most often the result of poor care orjudgement on the part of the operator whenmounting or adjusting the blade or supportguides.The most common causes of blade break-age are: (1) faulty alignment and adjustment ofthe guides; (2) forcing or twisting a wide bladearound a curve or short radius; (3) feeding toofast; (4) tooth dullness or absence of sufficientset; (5) excessive tension; (6) upper blade guideassembly set too high above the workpiece; (7)using a blade with a lumpy or improperly finishedweld; and (8), continuously running the bandsawwhen not in use.

To remove the blade, ensure the power is dis-connected and:

1. Loosen tension on the blade by turning thetension control knob counter-clockwisewhen facing the front of the saw. SeeFigure 9 .

2. Remove the table insert (#68) and table pin(#71).

3. Adjust upper and lower guide blocks awayfrom the blade.

4. Open the upper and lower wheel coversand slide the blade off both wheels. Usecaution, the blades are sharp!

5. Rotate the blade 90° so it will slide throughthe slot in the table.

NOTE: When removing or installing wide blades,it may be convenient to completely remove theupper and lower guide blocks. Be sure toreplace them before cutting!

To replace the blade, ensure that the power isdisconnected and:

1. Slide the blade through the table slot,ensuring that the teeth are pointing downtoward the table.

If the teeth will not point downward in anyorientation, the blade is inside out. SeeFigure 13 for typical blade geometry. Put onheavy gloves, remove the blade, and twist ituntil it is right side out. Re-install the blade.

2. Slip the blade through the upper and lowerguides and mount over the upper and lowerwheels.

3. Apply tension to the blade by turning thetension control knob. Refer to blade ten-sioning instructions earlier in this section.

Changing Blades

4. Rotate the upper wheel manually andcheck blade tracking.

5. Adjust the upper and lower guide blocksand bearings as described earlier in thissection.

6. Close the wheel covers. Turn the yellowguard locking knobs to lock them shut.

7. Replace the table insert and table pin,being sure not to use excessive force.

Use extreme caution when replacing blades.Teeth are dangerously sharp and coiledblades are prone to spring when releasedfrom their packaging. Use gloves and safetyglasses or goggles whenever handlingblades. Failure to do so could result in seri-ous personal injury.

G1148 15" Bandsaw -21-

Stacked Cuts

One of the benefits of a bandsaw is its ability tocut multiple copies of a particular shape by stack-ing a number of workpieces together.

Before making stacked cuts, it is essential toensure that both the table and the blade are prop-erly adjusted to 90°. Otherwise, any error will becompounded with each piece cut from the top tothe bottom of the stack.

To complete a stacked cut:

1. Align your pieces from top to bottom toensure that each piece has adequate scrapto provide a clean, unhampered cut.

2. Using brads in the waste portion of eachpiece, secure all the pieces together.

3. Lay out the shape you intend to cut on theface of the top piece.

4. Make relief cuts perpendicular to the outlineof your intended shape in areas wherechanges in blade direction could strain thewoodgrain or cause the blade kerf to bind.

5. Cut the stack of pieces as though you werecutting a single piece. Follow you layout linewith the blade kerf on the waste side of yourline.

Ripping is the process of cutting a board into twoor more thinner boards. The maximum boardwidth that can be ripped is limited by the distancebetween the blade and the support column. max-imum cutting height of the bandsaw. Maximumcutting width for this bandsaw is 145/8".

The G1148 bandsaw is capable of ripping, pro-vided the saw is set up properly. Use commonsense when ripping. Attempting to rip too thick ortoo dense a board may put excessive strain onthe blade and be dangerous.

The important consideration when ripping isblade selection. Generally, the wider blade, thebetter. In most applications, a hook or skip toothstyle will be sufficient. Also, since most rippedlumber will be planed or sanded smooth, you canchoose blades with fewer teeth-per-inch. Whileblades with fewer teeth-per-inch produce roughercuts, these types of blades offer larger gulletcapacities for clearing sawdust, less heat buildup,and yield more horsepower per tooth.

Ripping

To perform ripping operations:

1. The bandsaw must be adjusted correctly.See Blade Tension/Tracking section.

2. The table must be square to the blade. SeeTable Adjustment Section.

3. Use the widest blade available. The blademust also be in good condition.

4. Use a fence to guide work.

5. Draw a reference line on the edge of theboard.

6. Support ends of the board if necessary.

7. Feed work slowly and evenly.


Cutting Curves

When cutting curves, simultaneously feed andturn the stock carefully so that the blade followsthe layout line without being twisted. If a curve isso abrupt that it would be necessary to repeated-ly back up and cut a new kerf, use either a nar-rower blade or a blade with more set to avoid that.A blade with more set can cut relatively tighterradii; however, the cut is usually rougher than cutsproduced by blades with medium set.

Always make short cuts first, then proceed to thelonger cuts. Relief cuts will also reduce thechance that the blade will be pinched or twisted.Relief cuts are cuts made through the waste por-tion of the workpiece and are stopped at the lay-out line. As you cut along the layout line, wastewood is released from the workpiece, alleviatingany pressure on the back of the blade. Relief cutsalso make backing the workpiece out easier, ifneeded. The table below lists blade widths andcorresponding minimum radii each blade will cut.

BLADE WIDTH1/8"3/16"1/4"3/8"1/2"5/8"3/4"

MINIMUM RADII3/16"5/16"5/8"

1 1/2"2 1/2"

4"5 1/2"

Resawing

Resawing is the process of cutting a board intotwo or more thinner boards. Each new board isthe same width and length as the original board,but the thickness is less. The maximum boardwidth that can be resawn is limited by the maxi-mum cutting height of the bandsaw. Maximumcutting height for this bandsaw is 7 7/8".

Use common sense when resawing; attempting toresaw a board that is too wide or too dense mayput excessive strain on the blade and be unsafe.

Again, the important consideration when resaw-ing is blade selection. When selecting a blade,keep in mind that generally, a wider blade is eas-ier to control. The blade should be of the bestquality in order to handle the increased stress. Inmost applications a hook or skip tooth style willwork fine. Also, since most resawn lumber will beplaned smooth, you can choose blades with fewerteeth per inch (3 to 6). While blades with fewerteeth per inch produce rougher cuts, these typesof blades offer larger gullet capacities for clearingsawdust, less heat build up, and yield morehorsepower per tooth.

NOTE: When operating with wide blades, run thebandsaw at the slowest speed.

To resaw lumber, follow the procedure below:

1. The blade must be adjusted correctly.

2. The table must be square to the blade.

3. Use the widest blade that will fit this saw(3/4"). The blade must also be in good con-dition.

4. Use the fence to guide the work.

5. Support ends of the board if necessary.

6. Feed work slowly and evenly.

When using a fence to guide the board, the actu-al line of cut may not be parallel to the fence. Infact, most bandsaw blades will not cut exactlyparallel to the fence (even when the fence is setparallel to the miter gauge slot). There are usual-ly a number of reasons for this:

1. Teeth are set unequally from side to side.

2. Teeth are dull on one side.

3. Blade tension is too tight or too loose.

IMPORTANT: Do not force the wood into theblade during cutting. This will distort the blade,cause excessive heat and often results in bladebreakage as well as miscut lumber.

G1148 15" Bandsaw -23-

SECTION 7: MAINTENANCE

V-Belts

To ensure optimum power transmission from themotor to the blade, the V-belt must be in goodcondition and operate under proper tension. Beltsshould be checked for cracks, fraying and wear.Belt tension should be checked at least every 3months; more often if the bandsaw is used daily.

The V-belt is accessed via the bottom cover #25:

1. Squeeze the center of each V-belt.

2. Note the amount of deflection. Deflectionshould be approximately 3⁄4".

The table and other non-painted surfaces on theModel G1258 should be protected against rustand pitting. Wiping the saw clean after every useensures that moisture from wood dust isn’tallowed to trap moisture against bare metal sur-faces.

Some woodworkers recommend using automo-tive paste wax on exposed steel and cast iron sur-faces. The wax provides a layer of protection, aswell as reducing friction between lumber and thetable, making cuts faster and smoother. Avoidwaxes that contain silicone or other syntheticingredients. These materials can find their wayinto lumber that’s being worked, and can makestaining and finishing difficult. If you use pastewax, make sure that it’s 100% Carnauba wax.

NOTICEDo not use paraffin or similar waxes on yoursaw’s table. They can leave residues whichwill make cutting more difficult over time.Do not use silicon based lubricants. Theycan rub off onto the wood and prevent itfrom taking stains and finishes properly.

Table

Make your workshop “child-safe.” Removeall safety keys from this and other machin-ery when they’re not in use. Place sharptools and blades high enough to discouragecurious fingers. Store lubricants, finishesand other harmful chemicals where theycan’t be easily reached. Lock your work-shop securely when you are away.


-24- G1148 15" Bandsaw

Shielded and pre-lubricated ball bearings requireno lubrication for the life of the bearings. All bear-ings are standard sizes and replacements can bepurchased from our parts department or bearingsupply store.

As for other items on this machine, such asadjustment controls, an occasional “shot” of lightoil is just about all that is necessary. Before apply-ing, however, wipe off any sawdust with a cleancloth, towel or dry paint brush and spray on thelubricant. Ensure that oil does not get on the pul-leys or V-belts because it could cause belt deteri-oration and slipping.

Lubrication

Always be aware of the condition of your band-saw before using it. Routinely check the conditionof the following items and repair or replace asnecessary.

1. Loose mounting bolts.

2. Worn switch.

3. Worn or damaged blade.

4. Worn or damaged support bearings orguide bearings.
