SPECIAL ADJUSTMENTS
4-6 CUTTERHEAD REPLACEMENT:
The condition of the cutterhead should be inspected daily. The cutterhead knives are carbide which
means that anything metallic, either in the door or stuck to it, will chip or actually break one or more
knives. It is good practice never to put a door “edge down” on the floor as foreign particles (rocks, dirt,
metal particles, screws, etc.) may be picked up by the edge of the door. A chip in the cutterhead will show
up on the door as a ridge the entire length of the beveled edge.
To replace the cutterhead:
1. Turn off all electrical power and lock and tag-out the machine .
2. Open the front cover to expose cutterhead and powerfeed wheels.
3. Remove locking pin from first powerfeed plate.
4. Remove the cap on cutterhead vacuum shroud.
5. Using two wrenches, hold the mandrel shaft and loosen the cutterhead nut. (LH threads on mandrel
shaft).
6. Remove dull cutterhead and replace or replace disposable insert blades.
7. Reinstall the nut, vacuum cap, powerfeed plate locking pin and close the cover.
4-7 CUTTERHEAD MOTOR DRIVE BELT:
The use of a dull Cutterhead will shorten the life of the mandrel
bearings, drive belt and the motor.
Your cutterhead motor is equipped with a motor base/belt tension device. Loosen the lock nuts securing
the motor base to the rails (not screws that secure rails to frame) and turn the adjusting bolts clockwise
to force the motor away from the cutterhead mandrel. Be careful to keep the motor drive pulley aligned
with the mandrel pulley. After taking up the slack in the belt, tighten the lock nuts. Check for 1/4” deflec
-
tion of the belt at center between the motor pulley and mandrel pulley.
4-8 SANDING WHEELS REPLACEMENT:
1. Turn off all electrical power and lock and tag-out the machine.
2. Open the powerfeed cover and the locking pin from the second powerfeed plate.
3. Use a punch to keep shaft from rotating while loosening the locking nut.
4. Note carefully the side of the sander wheel which has the abrasive and replace the new wheels one
at a time. The two shafts turn toward each other so the wheel goes on the first shaft, the closer of the
two shafts, with the abrasive at the top of the wheel toward the door. The second sander wheel goes
on the rear shaft also with the abrasive toward the door Be careful not to loose the bushings.
