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

service personnel. In the event unusual
environmental operating conditions exist, the
schedule should be adjusted accordingly.

machine is not operating. Maintain the fluid
level between bottom and midway of the
sight glass on the separator tank.
Air Cleaner
If this unit is equipped with the Optional
Diagnostic Panel, it has an AIR FILTERS
RESTRICTED lamp on the instrument panel,

unit operating at full speed, servicing of the
cleaner element is necessary.
Also weekly squeeze the rubber valve
(precleaner dirt dump) on each air cleaner
housing to ensure that they are not clogged.
The air filters restricted sensor will
automatically reset after the main power
switch is turned to “OFF.”
