OPERATING INSTRUCTIONS PLANING
A. Check machine to make sure all bolts, nuts & wrenches have been
removed from the machine.
B. Turn machine on and visually check proper rotation of feed rollers.
CAUTION: KEEP HANDS AWAY FROM ALL MOVING PARTS
C. Planing Operation:
WITH MACHINE TURNED OFF
1. Place a board (3 to 4 ft. long) to be planed under the infeed roller.
2. Turn the crank handle to raise the planer bed so the board just con-
tacts the roller.
3. Remove the board.
4. Turn the bed crank four full turns up. (This will allow contact with
the top of the cutterhead knives and removing high spots on the
board.)
NOTE: FEED BOARD INTO MACHINE STRAIGHT.
CAUTION: DO NOT STAND IN FRONT OR BEHIND MACHINE WHEN IN
OPERATION.
TURN THE MACHINE ON
5. Start the board into the machine so it will travel in a straight line.
6. Turn bed crank to desired depth of cut and feed board through again.
7. Depth of cut information:
Turn crank handle 1/4 turn = 1/64 inch cut
Turn crank handle 1/2 turn = 1/32 inch cut
Turn crank handle 1 turn = 1/16 inch cut
LUBRICATION
NOTE: PARTS ON THIS PAGE ARE REFERRED BY KEY # TO SCHEMATIC
DRAWING PAGE #14,15
Corner Screw (Key #47) and Crank Screw (Key #46)
2 - 4 drops of oil at the bed contact and bottom wear washer, as
required for ease of turning.
Feed Roll Bearings (Key #6)
2 - 4 drops on the roller shaft at the side of the bronze bearing every
20 hours of operation or more often under severe or intermittent use.
Dual V-Pulley (Key #22)
2 drops to (Key 21) Bushings every 8 hours of operation.
LUBRICATION
Lubricate Electric Motor, if required, according to instructions supplied
with motor. Grease Reduction Unit Assembly every 40 Hrs. of operation.
Do Not over-grease as excess will cause belt slippage.
Bed & Extension Surfaces
Apply paste wax or paraffin to prevent rust and to reduce fraction and
increase ease of feeding on bed and extension tables.

4. Tighten set screws in gib just enough to hold knife in place
centered in the cutterhead.
crf0~E 5. Adjust knife gauge as shown in diagram so plunger is 1/8"
below top. (Allen screw locks plunger guide in position)
CUTIER 6. Place the knife gauge over the knife with the bottom of the
HEAD plunger on the knife edge.
7. Adjust the knife up by turning the adjusting jack screw counter-
clock-wise until the knife gauge plunger is level with top of the
plunger guide (se diagram)
;- FLAT 8. Check the full length of the knife for equal adjustment.
9. If uneven, check to see if gib is too tight, binding knife
movement.
10. When even, tighten set screws in gibs and recheck knite length.

Increasing and Decreasing Infeed & Outfeed Roller Tension
1. Loosen jam nuts
2. Screw lower nut down (clockwise) to increase roller pressure.
Screw it up, counter-clock-wise, to reduce roller pressure.

Bed Height Adjustment
1. The crank is used on the crank screw to raise and lower the bed.
2. Clock-wise turning raises the bed.
Counter-clock-wise lowers the bed.
;3. Each complete turn raises or lowers the bed 1/16 inch. Max. cut
no more than 3/16 in. (3 full turns).
Cutterhead Drive Belt
1. Loosen the adjusting stud and let the motor mount hinge down
using the weight of the motor to tension the belt. Secure the adjust-

fourth lower than the other, turn the two RS-41 RS-34-A or RS-5-A
assemblies on the lower side clockwise to raise the table 114 turn

Cleaning Feed Rollers
During extended periods of time and under moist wood operation,
a build up of resin can occur on the roller. This can be removed by
wiping with Kerosene.
CAUTION: KNIVES ARE SHARP I
"'------------
Knife Sharpening
A. MAJOR. The beveled edge of the knife should be ground to a 30°
or 45
0
angle, the straight length of the knife to remove all nicks and
notches.
B. MINOR. Between major sharpenings a hone may be used on the
fiat side of the knife cutting edge, evenly the full length of the
knife.
Roller Chain Tightening
Adjust the tension on the feed table adjusting chain by sliding the
adjustment bracket RB-45 on the base assembly.
