LUBRICATION
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Figure 12 shows lubrication points for the backhoe.
It is recommended that all fittings be lubricated daily or
every eight hours of operation. In very wet or dry condi-
tions, lubricate every four hours of operation.
Use an SAE multi-purpose type grease for all locations
shown unless otherwise specified. Be sure to clean fit-
ting thoroughly before using grease gun. One good
pump of most guns is sufficient.
Position backhoe for easy lubrication by placing boom
and dipper at 90° to each other with bucket cutting
edge vertical and teeth resting on ground. Lower stabi-
lizers to lubricate cylinders.
