WARNING: Always stop the PTO, turn off the engine and remove the key before
performing any inspection, maintenance, adjustments or cleaning.
Lubricate:
PTO shaft — 2 zerks on universals once a day with multipurpose grease.
Slip Joint — Lubricate with multi-purpose grease.
Feed roll pivot — 2 zerks on underside of chute end. Multipurpose grease every 4 to 8
hours of operation. If dust or fine particles make pivot bind, unhook feed roll springs,
use cleaning solvent on pivot while moving up and down, wipe off, lubricate slides,
and replace springs.
Feed roll drive-shaft — Zerk on feed roll drive-shaft lubricates both the slide and both
universal joints. Add multipurpose grease until grease shows at both universals every
4 to 8 hours of operation, particularly before each use. Occasionally remove and
thoroughly clean this assembly.
Feed roll clutch — While feed roll shaft is off, lubricate the feed roll clutch inside and
outside with multipurpose grease.
Gear box — Check label on the gear box for gear box lubrication.
Check all bolts, set-screws and fasteners after running four hours, and once per day
thereafter.
Check for loose belts and broken pulleys, loose springs, dry slides and proper
lubrication of both feed roll drive-line and feed roll clutch.
The main drive belts on the chipper need co be tight. To tighten these belts, first
loosen the four bottom nuts that hold the jack-shaft bearing. Loosen them about three
turns, then move the nuts on the top of the bearings down an equal amount. Keep the
jack-shaft parallel with the main shaft. Torque the bottom nuts to 80 ft.-lbs.
The belts of the main drive on the PTO chipper should be checked every 8 hours of
operation.
Look for cracks, looseness or other signs of deterioration. For best performance,
replace with a matched set of eight belts.
The feed roll drive belt can be adjusted by first loosening the four bolts that hold the
worm gear box to the base, then moving the gear box away from the chute and
re-torques the bolts to 40 ft.-lbs.
All decals and safety instructions should be kept clean and legible. It is the operator’s
responsibility to replace the decals as needed (they will be mailed at no charge).
