LUBRICATION

The cutterhead, cutterhead motor. and the feed motor (on machines so equipped) have lubricated for life bearings and need no lubrication.

Grease gun fittings and locations: 1. Top and bottom. left and right infeed roll

bearings. Reached from the infeed end of the machine between the table and infeed girt.

2. Top and bottom, left and right outfeed roll bearings. Reached from the outfeed end of the machine .between the table and outfeed girt.

3. Right idler sprocket bearing and right end of feed drive shaft. Reached from the infeed end of the machine between the table and infeed girt.

4. Flat belt pulley bearing. Located from infeed end of machine under the table through a hole in the left side frame.

5. Left chain tightener sprocket bearing. Door opened.

6. Feed drive shaft, left end. Door opened. 7. Hoist the shaft sprocket idler bearing. Door

opened. 8. Belt tightener arm. Door opened. (Not on

motorized feed drive machine.) 9. The belted feed drive machine is equipped

with an Ideal variable speed pulley. Each day the pulley should be run through its entire speed -range. Lubricate the ulley every .1.5 da s with a smaiTamount of lubricant. Bleed

eslU-e provided to- e outside of the outer disc to prevent any excess grease from get­ting on the belt. Additional information on the pulley can be found in the pamphlet accomp-

( --,_nying the Instructions and Parts List.

10. jl'he motor drive feed machine is equipped with a Reeves vari-speed motor pulley. Each day

the pulley should be run through its entire speed range. Lubricate the pulley ever 30 days with enough grease so that the~se will a_ppear_at the bleed holes located on the

, .. outside of the outer disc. Additional informa­tion on the pulley can be found in the pamphlet accompanying the Instructions and Parts List.

11. Drive gear and sprocket bearing. Door open. 12. V-belt pulley and pinion bearings. Door open.

With the exception of the variable speed pulley lubricate all bearings with grease gun fittings twice a week. Use any good neutral petroleum gun grease such as Superla No. 42 (Standard Oil Company of Indiana) or equivalent.

The four collars for the chipbreaker and pres­sure bars are equipped with dot oilers. Oil once a week with a fairly light machine oil that pene­trates well.

Oil the chains once a week with a good grade of SAE No. 40 oil.

ALIGNMENT AND ADJUSTMENTS

The B-244 Surfacer was properly aligned at the factory before shipment. If necessary to realign it, proceed as follows:

Level the bed with the head, using a block of

Instructions and Parts List

hardwood, about 2 11 x 4 11 x 4 11 for a gauge. Place this gauge on the platen under the head and raise the bed until the knives just touch the gauge. Try the gauge at each end of the knives. If necessary raise one side of the bed to bring it in line, by means of the slotted adjusting screws at the bot­tom of the hoist screws.

After the bed is leveled. check the pressure bar after the cut. The simplest way to set this bar is to run two strips of lumber, one through each side of the machine. When they have reached the out rolls. stop the machine. By means of the set screws on each end of the pressure bar adjust the bar so it just touches the lumber. The pressure bar should touch the lumber. but it should not clamp it so tightly that the lumber will not feed out freely.

To adjust the chipbreaker and top rolls, lower the bed 1/ 32 11 (1 / 2 turn of the hoist handwheel) and bring the rolls and chipbreaker to touch the same gauge block. The set screw for adjusting the chipbreaker is the one which supports the chip­breaker weight lever. The top rolls are adjusted by the two lock nuts just beneath the roll bearing housings. The chipbreaker which swings concentric with the cutterhead, yields 1/ 2 11

• Each section in the sectional chipbreaker yields 1/ 8 11

• The top in­feed roll has 1/ 2" yield through spring pressure. Each section in the sectional roll has a yield of 1/ 8".

The bottom rolls have been set, at the factory, . 007 above the platen. Each end of the bottom rolls is supported in a steel bearing plate which is bolted to the side of the table. If necessary, the bottom rolls may be adjusted by loosening the cap screws which hold the bearing plates in place and raising or lowering the bearing plates by means of the set screws lo~ated below the bear­ing plates.

The bearing plates also serve as gibs for guiding the table. Each of the two infeed bearing plates is backed up by a set screw to take up any wear. These set screws can be located from underneath the table.

The top feed roll pressure can be changed by means of the two lock nuts under each of the four pressure springs.

To tighten the feed drive chain. loosen the set screw holding the eccentric stud upon which the chain tightener sprocket is mounted. Turn the ec­centric enough to tighten the chain and then lock it in place with the set screw.

If the bottom roll drive chain on the r~ght side of the table needs tightening or replacing, the con­trol box under the motor must be removed to gain access to the chain.

When installing a new flat Vee belt. a slight adjustment of the flat Vee belt driven pulley may be necessary. This is done by removing the bolt holding the adjusting eyebolt to the gear quadrant and then turning. the eyebolt as required.

For B-244 Surfacer

10INTING AND GRINDING THE KNIVES

The knives on the B-244 Surfacer have been ground and jointed at the factory with the jointing and grinding attachment which accompanies the machine. When mounting the jointer bar on the joiitter bar brackets be sure that the bar fits flat against the brackets. The brackets have a set screw and cap screw to make adjustments if ne­cessary. Align the jointer bar with the head body by moving the jointer stone across the head body using a thin piece of paper as a gauge between the head body and the jointer stone. DO NOT align the bar with the edge of the knives. Adjusting screws are located on each end of the jointer bar for ver-tical alignment. '

In order to have all knives doing their share of cutting at operating speeds. we recommend grind­ing the knives, then lightly jointing off the edges while the heads are running at full speed.

When the knives become dull they should be re­jointed. The number of times a knife may be jointed before it has to be reground. depends up­on the width of the heel or line caused by the jointing stone. When the heel becomes too wide the knives· may heat up or have a hammering ef­fect on the wood and more than normal power will be required to run the head. The amount of heel which can be used depends on the kind and condi­tion of wood being worked. Kiln dried hardwood will stand a wider heel than kiln dried softwood and air dried softwood will stand the least. In general. the heel should not be wider than 1/32 11

•

Always set the jointing stone while the head is at rest. Move the stone towards the head until the stone just touches the edge of each knife along its full length. If the stone does not touch all the knives quite uniformly across their entire length the knives which are out of position must be reset or the knives ground over. Now move the stone back slightly so there will be no danger of the knives hitting the stone when the head is started. After the head has reached full speed, carefully bring the stone just up to the knives and then pass the jointer back and forth along the full length of the head, adjusting the stone very slightly towards the knives at the end of each stroke. After 2 or 3 strokes have been made , run the stone back and forth across the head several times without t~rning it down so the ends of the knives will not have a larger joint and a slightly smaller cutting circle than the center portion of the knives.

When it becomes necessary to grind the knives. they should be ground just enough to remove the old joint. When grinding the knives in place on the machine, do not take such a heavy cut that the speed of the grinding wheel is slowed down. Use the knife stop to keep the knife in proper position. Move the grinder across the knife fast enough so that the edge of the knife will not become burned. Do not try to completely grind one knife at a time. but grilld all of the knives at one setting of the grinding wheel. then set the grinder down and grind all the knives at this setting. The cut on the last setting should be quite light. Keep the grinding wheel well dressed and occasionally wipe the dust from the slide.

.-

STARTING

Connect the control box to the main power line. The three terminals to which the outside leads should be connected are located in the control case below the motor. The B-244 Surfacer is a self­contained electric-driven machine. All internal wiring is done and tested at the factory and all adjustments are made for the proper running of the motor.

Be sure the head turns freely before pushing the start button.

When ready to start be sure the main line switch is in. If the machine does not start. be sure that the current is coming to the machine before look­ing for trouble elsewhere.

If a 3-pha'.se motor runs in the wrong direction, reverse any two leads.

CONTROLS

The table is raised and lowered by the large handwheel on the left side of the machine.

The feed speed is controlled by the speed regu­lator on left front side of the machine. DO NOT CHANGE THE FEED SPEED UNLESS THE FEED WORKS IS RUNNING.

On the B-244 Surfacer with the feed works driven from the cutterhead the feed can be started and stopped by pushing in and pulling out the feed con­trol lever above the speed regulator.

On the B - 244 Surfacer with a separate feed motor the head is started and stopped-.-by the left set of push buttons and the feed· works by the right set of pushbuttons. This type of machine also has a brake for the cutterhead. The brake pull rod is located above the feed speed regulator. Do not ap­ply the brake until the current to the cutterhead motor has been turned off.

RESETTING RELAYS ·

The common cause of relays throwing out is at­tempting to start the motor when the head or the feed works is blocked and the motors cannot turn freely. Another cause is overloading.

If the relays have thrown out. determine and correct the cause of the relays throwing out before the machine is started. Allow about a minute or two for the relays to cool before pushing the but­ton marked "reset 11

•

CARE OF ELECTRICAL EQUIPMENT

The principle causes of motor trouble outside of overloading are moisture and dirt. The fact that an electric motor will continue to operate under extraordinary conditions of dirt and moisture does not mean that the average motor should be ex­pected to do so regularly. Dirt. however. is the greatest enemy of electrical equipment. Any kind of dust that is capable of clogging up the ventilat­ing ducts will cause a rise in temperature and the life of the motor is greatly shortened when the rise in temperature is higher than that given on the nameplate of the motor.

The head motor and the feed motor (on machines so equipped) should occasionally be blown out with dry compressed air to keep all air ducts open.
