LUBRICATIONDrain and replace lubricant (gear oil) after the first 10hours of operation and after each 50 hours ofoperation thereafter.

Keep the front gear case and rear gear case properlyfilled with gear oil. This level may be checked byremoving oil plugs on gear cases while machine islying on level surface. Drive spindle and indicatorswould be on top during this check. Oil level should beeven with gear case oil lug threads.

CL-12 Machine requires four pints (4 lbs.) of gear oil infront gear case and four pints in rear gear case.

Mueller Part No. 89347 gear oil is used. This gear oilneeds no thinning in cold weather.

PACKINGBoring bar packing on machines is a “V” or chevrontype packing, which is automatically adjusted by aspring. There is no take up. When packings leak, theyshould be replaced with new ones. Packings are goodfor water, gas, or petroleum products.

To replace Boring bar packing, see Special Instructionson page 20.

Packing leakage may be determined by observing twosmall drain holes in sides of machine behind frontflange. These vents prevent pressure from enteringinto the gear case.

All oil seals in CL-12 Machines are “o” ring seals, whichare non-adjustable. If leakage occurs, new “o” rings arerequired.

CUTTING EQUIPMENTSharpen cutters and point drills by touching them upwith an oilstone before each cut. Front edge of cuttertips should be lightly honed.

If cutters are very dull or show excessive wear, returnto MUELLER CO. for reconditioning.CAUTION: Keeping cutters sharp assures maxi-mum efficiency in cutting operations. Whencutters are dull they not only make cutting moredifficult, but place an additional strain on thetips which can cause tip breakage.

When not in use keep cutters in a wooden container.NOTE: Be careful not to drop cutter and damage

cutter tips.) If necessary to set cutter on tips, placeupon wood rather than brick, concrete or metal.

Cutters used with CL-12 Machines are tungstencarbide tipped for making lateral connectionsthrough tapping valves.

Tungsten carbide tipped cutters are designed forcutting cast iron, cement-lined cast iron, asbestos-cement reinforced concrete and steel pipe.

A cutter which has been used on cast iron or steelpipe can be used on cement-lined, asbestos-cementor reinforced concrete pipe without resharpening.

A cutter which has been used on abrasive materialscannot be used on metal pipe without resharpening.

Steel cutter hubs are used with CL-12 Machines.

All pilot drills are threaded into the cutter hub withthread sizes arranged to prevent wrong use of drillsand cutters. Drills are provided with wrench flatspermitting removal of pilot without removing cutter.All pilot drills have spring loaded detents to retaincoupon cut by shell cutter. These detents areremovable for cleaning or replacement.

Always check detents before using to be sure they areoperating correctly.

AFTER USEDirt and excess grease should be cleaned frommachine after use. Boring bar should be given a lightcoat of oil of prevent rust, and this should be donewith boring bar slightly extended. Oiled bar will pulllubrication into packings as bar is retracted.

Cutters, drills, hubs, etc. should be lightly oiled after uuse to prevent rusting.

STORAGEWhen not is use the CL-12 Machine should be keptin wooden chest during period of being transportedto jobs or stored.

Place machine and adapter against valve,allowing cutter and pilot drill to extend into theend of the valve. FIGURE 12. Install bolt and nutsand tighten evenly to valve.

10. Test set up for pressure tightness with water.

11. Lay a scale or rule alongside the tapping sleeveand valve and measure the machine adapter topipe distance. FIGURE 13. This distance, plus orminus the amount the pilot drill extends or isbehind the face of the machine adapter flange,isthe approximate distance the pilot drill shouldtravel to reach the main.

12. Rotate feed crank handle clockwise to advancethe boring bar until the pilot drill contacts themain.

Tool Position Indicator (see FIGURE 3) shouldnow read the approximate amount that wascomputed in instruction 11.

CAUTION: If Tool Position Indicator doesnot read approximately the same as thecomputed amount, it indicates that thepilot drill has encountered an obstructionand is not contacting the main.

13. Check to be sure Automatic Feed Set Knob isdisengaged. (Push in on knob to disengage.) TurnAutomatic Feed Set Knob counter-clockwise toset the desired amount of Automatic feed onAutomatic Feed Travel Indicator. FIGURE 15. Pullout on Automatic Feed Set Knob to engage theautomatic Feed Travel Indicator after correctamount has been set. See Travel Charts on page16, 17, 18 and 19.

While cut is being made, the amount set on theautomatic Feed Travel Indicator, see FIGURE 3,will subtract until the completion of the cut. It willthen register 000.

NOTE: It is always necessary to pre-set for someamount of feed to permit machine to auto-matically advance the boring bar, otherwise itwill not feed.

To replace or reset either Indicator, see SpecialInstructions on page 20.

14. Pull out on Automatic Feed Engagement Knoband rotate feed crank counter-clockwise untildive key engages. FIGURE 16. This can be feltwhen crank handle ceases to freely rotate, Thisrotation releases the tension between pilot drilland main and does not change the pre-setdisengagement point.

15A. When hand operating the CL-12 Machine –Loosen the pivot thumb screw. This permits thepivot pin to be removed so that the front liftingyoke may be removed.

Attach ratchet handle to drive spindle and set theclockwise rotation. Always operate the machineaccording to instructions with one man only onratchet and using automatic feed to assurecorrect drilling and tapping rate.

FIGURE 12

FIGURE 13

FIGURE 14

11


If cut becomes too difficult for one man, do notforce machine as this may damage cutter ormachine. Follow one of the methods listed ininstruction 23.

Hand operated CL-12 Machine should have aboring bar advance of about .015” per minute, ifoperator can maintain 5 RPM on input spindle.This rate would require about 60 minutes toadvance one inch. Smaller cuts permit higherinput speed and cutting times will be reducedaccordingly.

15B. When power operating the CL-12 Machine withthe Mueller H-614 Air Power Operator or H607Hydraulic Power Operator

Loosen the pivot thumb screw, this permits thepivot pin to be removed so that the front liftingyoke may be removed and the operator may beattached to the holder pivot on the front gearcase of the CL-12 Machine. Position the operator

and replace pivot pin. Tighten the pivot thumbscrew and latch the operator in position with thebolt and wing nut latch provided on gear case toprevent movement.

Open operator throttle fully.

Important: Maintain 90 psi air pressure for theH614 Air Power Operator and 1500 psig for theH607 Hydraulic Power Operator. These presuresshould be measured at the operator with gauge.

When power operating the CL-12 Machine, theboring bar in automatic feed should advanceabout .187 per minute or require 5+ minutes toadvance an inch.

If cutting becomes difficult and stalling occursfollow on the the methods listed in instruction 23.

16. Continue cutting operation until automatic feeddisengages. If for some reason the presetautomatic feed was set for more than the travelremaining in machine, feed will be automaticallydisengaged when boring bar travel limit isreached. When cut is completed, both theAutomatic Feed Set Knob and Automatic FeedEngagement Knob will be in the forward ordisengaged positions. FIGURE 19.

If the pre-set automatic feed was not disengagedwhen cutting is completed for some reason, asafety device is built in to prevent damage to thismechanism.

17. Check to see if cut is completed by attempting toadvance boring bar by hand advance. Rotatecrank clockwise. See FIGURE 4. If boring baradvances easily, cut is completed.

18. Rotate crank handle counter-clockwise to returnboring bar to rearmost position. See FIGURE 10.

19. Close valve securely.

20. Remove the power operator with its holder fromthe machine pivot.

21. Unbolt adapter from valve and remove adapter,cutting equipment, and drilling machine as aunit.

22. Advance boring bar by rotating feed crankclockwise until cuter hub retaining screw isexposed. Remove retaining screw and removecutter hub, pilot drill, and cut-out section of pipeor coupon.*

If pilot or cutter is to be removed hub, leave hubon boring bar until pilot drill is loosened andcutter is loosened from hub.*

To remove the shell cutter from the E-Z ReleaseCutter Hub, loosen allen head cap screws inbacking ring. Shell Cutter may then be easilytaken off.*

Coupon may be slipped over pilot drill detentsand out of cutter or pilot may be removed fromhub to remove coupon.*

*Replace the front lifting yoke and place the frontlifting yoke over the square drive spindle to preventrotation of boring bar when removing tools. SeeFIGURE 9.

23. If cutting operation becomes difficult, follow oneto these methods.a. If cutter has difficulty in cutting, becomes dull

or should stall after the cut is started it isprobably due to scale on the main or excessivehardness of pipe.

b. Mark down the settings on both the AutomaticFeed Travel Indicator and the tool PositionIndicator, This is for reference whenreassembling the set up.

c. Push in on both Automatic Feed Set Knob andAutomatic Feed Engagement Knob – this willdisengage the Automatic Feed Travel Indicatorand will also disengage the automatic feed.
