Grease Fittings
Your 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.
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.
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 26) , each PTO Bearing Grease Fitting (Figure 27) , and the two U-
Joint Grease Fittings (Figure 28).
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.
