Charge Hydraulic System
NOTE: When initially starting the hydraulic system with
new or rebuilt components such as motors, pumps or lift
cylinders, it is important that the hydraulic system be
charged properly. Air must be purged from the system
to reduce the chance of component damage.

10 to 15 seconds, or the pump emits abnormal sounds,
shut the engine off immediately and determine cause or
problem. Inspect for the following:
IMPORTANT: Change hydraulic oil filters whenever
hydraulic components are repaired or replaced.
A. Loose filter or suction lines.
B. Blocked suction line.

The charge pump should pick up oil and fill the hydraulic
system. If there is no indication of fill in thirty (30) se-
conds, stop the engine and determine the cause.
