D. Obtain access to the power unit components by removing
the bolts holding the upper cabinet doors closed. With the
cylinders fully retracted, confirm hydraulic fluid level. If
level is low:
1. Top off the reservoir with ISO 32 AW-type
hydraulic fluid
2. Search for leaks at hoses, fittings, and cylinder
rods. The hydraulic system is closed, and if
fluid level drops, it indicates a leak
somewhere.
E. Ensuring power is locked out according to the instructions
on page 2.6 of this manual, open the electrical enclosure
on the power unit. Check for loose wires or components.
Obviously, if there are signs of excess heat (scorched wire
coverings or components), tighten or service as needed.
F. Once per year, clean the breather/filler cap on the
reservoir.

Diagnosis & Repair
No individual should perform diagnosis or repair work on the
compactor unless he or she is qualified by his or her employer for
diagnosis and repair of electrical and hydraulic equipment. Improper
diagnosis and repair techniques, allowing contact with live electrical
power or exposing body parts to moving parts of the equipment can
result in injury and even death. Remember that even when the
equipment is off, hydraulic lines may retain some pressure. Do not
expose any body parts to the path of moving parts without suitable
blocking devices.
A. If the compaction platen descends and does not return to
its top position, but the compactor continues to run,
confirm the compaction platen has reached the bottom
limit switch. If it has, then locate and confirm proper
function of the bottom limit switch. If the compaction
