Upper and Lower Lubrication — Identification
NOTE 1 Inspect the crane daily for leaks. If a leak is
found, determine the cause, take corrective
action, and refill the applicable component with
proper fluid.
NOTE 2 Fill through the fitting in the base of the reservoir
using a hand-operated grease gun or pump.
Refill the reservoir when the grease reaches the
MIN mark. Fill the reservoir to the MAX mark.
The crawlers and turntable bearing are greased
automatically by electric pumps when the
ignition switch is on.
NOTE 3 Drain any accumulated water from the fuel and
hydraulic tanks at the start of each work day.
Crack open the quick-drain valve using the
quick-drain drainer assembly. Disconnect the
quick-drain drainer assembly as soon as water
stops draining and a steady stream of fuel or
hydraulic oil appears.
NOTE 4 Check the coolant level when the coolant is
cold.
