HYDRAULIC SYSTEM COMPONENTS
Hydraulic Fluid Reservoir
This consists of the tank, a filler cap with breather, a drain plug, and a bypass filler with a
10 micron filter element.
Perform the following steps weekly:
• Check tank for signs of leakage.
• Inspect tank securing bolts for tightness.
Hydraulic Filter
All machines are produced with a filter. It is a 10 micron spin-on, bypassing filter. When the filter is
clogged, hydraulic flow bypasses the filter element. The filter element must be changed every 6
months or 500 hours. Extremely dirty conditions may require that the filter be replaced more
often.
Beware of hot fluid. Contact with hot fluid may cause burns.
Hydraulic Pump
An electric motor drives the fixed displacement, gear pump. The pump provides hydraulic fluid
flow to operate the machine functions at 3 g.p.m. There are no adjustments on the pump. The
pump provides power for the lift, drive, brake and steering functions.
