Grease Fittings
Your GRAVITY SELF-FEEDING CHIPPER was greased at the Factory.
The operator needs to periodically lubricate the four Bearings of the
Chipper Assembly and the PTO Shaft.
Disengage PTO, shut down the tractor engine, remove the key, wait for all
moving parts to come to a complete stop, disconnect the PTO shaft from
the tractor, then wait 5 minutes before performing any maintenance procedure
or inspection on the chipper.
Tools and Supplies needed:
• Flexible hose grease gun
• Lithium grease
• Clean cloth
• 1/8" Allen Wrench
• Thread Lock
1. Remove the Belt Guard (see “Removing, Replacing and Adjusting the
Drive Belt” in this Chapter).
2. Wipe all dirt, etc., from the grease fittings with a clean cloth.
Over lubrication can damage the bearings.
3. Apply no more than three pumps of quality general-purpose lithium
grease with a hand-pumped grease gun to each Flywheel Bearing
Grease Fitting (Figure 25) , each PTO Bearing Grease Fitting (Figure
26) , and the two U- Joint Grease Fittings (Figure 27).
4. Check the Bearing Set Screws for tightness. If they are not tight then
remove them, apply Thread Lock to the threads, then reinstall and
tighten the Set Screws.
5. Replace the Belt Guard.
