Excavator unit, greasing
Grease the excavator unit every 50 hours or
weekly.
During the first 100 hours, the excavator unit should
be greased every 10 hours or daily.
NOTE!
Under severe operating conditions where mud,
water, and abrasive material may enter the
bearings, or after using the hydraulic hammer, the
excavator unit should be greased every 10 hours or
daily.
When greasing by hand, lower the attachment to
the ground as illustrated, and stop the engine.
Grease through the grease nipples using a hand or
power grease gun. After greasing, clean off the
superfluous grease.
Immediately after working under water, grease the
submerged parts such as the bucket pins to remove
the old grease, regardless of the grease interval.
