Maintenance
General
In addition to periodic inspections, many of the components in these units require periodic
servicing to provide maximum output and performance. Servicing may consist of pre-operation
and post-operation procedures to be performed by the operating or maintenance personnel.
The primary function of preventive maintenance is to prevent failure, and consequently, the
need for repair. Preventive maintenance is the easiest and the least expensive type of
maintenance. Maintaining your unit and keeping it clean at all times will facilitate servicing.
Scheduled Maintenance
The maintenance schedule is based on normal operation of the unit. This page can be
reproduced and used as a checklist by the service personnel. In the event unusual
environmental operating conditions exist, the schedule should be adjusted accordingly.
Compressor Oil Level
The oil level is most consistent when the unit is NOT running and should be checked at this
time. Remove the dipstick located on the right side of the airend. The oil level should be
between the high/low indicators on the dipstick.
Compressor Oil
This machine was factory filled with Portable Power Hydraulic Fluid.
Air Cleaner
This unit is equipped with an AIR FILTERS RESTRICTED message on the instrument panel.
When this message is viewed, both the engine and airend filters should be replaced.
Also weekly squeeze the rubber valve (precleaner dirt dump) on each air cleaner housing to
ensure that they are not clogged.
NOTICE
Holes or cracks downstream of the air cleaner housing will cause the
restriction indicators to be ineffective.
