SECTION 6 -- MAINTENANCE
CAUTION
Any unauthorized modification or failure to maintain
this equipment may make it unsafe and out of factory
warranty.
If performing more than visual inspections, disconnect
battery cables and open manual blowdown valve.
Use extreme care to avoid contacting hot surfaces
(engine exhaust manifold and piping, air receiver and
air discharge piping, etc.).
Never operate this machine with any guards removed.
Inch and metric hardware was used in the design and
assembly of this unit. Consult the parts manual for
clarification of usage.
Notice:
Disregard any maintenance pertaining to
components not provided on your machine.
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 should be checked before the unit is
started. Always check the oil level while the unit is
level, the engine off, and there is zero pressure in the
separator tank. The optimum oil level is with the
pointer at the top of the green section on the level
gage. Add oil if the pointer reaches the bottom of the
green section.
Note: The oil level gage will not read properly while the
engine is running.
YELLOW -- TOO HIGH
GREEN -- OK

AIR CLEANER
If this unit is equipped with the Optional Diagnostic
Panel, it has an AIR FILTERS RESTRICTED lamp on
the instrument panel, covering both the engine and
the compressor.
This should be checked daily during operation. If the
lamp glows (red) with the 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.”
