MAINTENANCE
CLEANING THE AIR FILTERS
A dirty air filter will
A
Fig. 5
reduce the compressor’s
performance and life. To
avoid any internal
contamination of the pump,
the filters should be
cleaned frequently, and
replaced on a regular
basis. Felt filters (A) should
be cleaned in warm, soapy
water, rinsed, and allowed
to air dry before
reinstallation. Paper filters should be replaced when dirty. Do not allow the
filters to become filled with dirt or paint. If the filter becomes filled with
paint, it should be replaced. Direct exposure to dirty conditions or painting
areas will void your warranty.
Note: Troubleshooting problems may have similar causes and solutions.
TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
Excessive current draw
trips circuit breaker or
motor reset switch
Low voltage/motor overload Check that power supply is adequate and that compressor is on a
dedicated circuit.
Drive belt tension too tight Readjust belt tension.
Restricted air passages Inspect and replace transfer tubes or the check valve.
Compressor stalls Low voltage to motor Furnish adequate power.
Low discharge pressure Air leaks Tighten or replace leaking fittings or connections. Do not overtighten.
Leaking valves Contact a qualified service center.
Restricted air intake Clean or replace air filter element(s).
Blown gaskets Contact a qualified service center.
Compressor pump
knocking
Loose motor pulley or pump
flywheel
Retighten pulley and flywheel. Check alignment.
Low oil level in pump crankcase Keep oil at proper level at all times.
Oil in discharge air
Restricted air intake Clean or replace the air filter element(s).
Oil level too high Reduce to proper level.
Overheating Poor ventilation Relocate compressor to an area with cool, dry, well circulated air, at
least 12 in. from nearest wall.
Dirty cooling surfaces Clean all cooling surfaces thoroughly.
Restricted air passages Inspect and replace transfer tubes or the check valve.
Excessive belt wear Pulley out of alignment Realign pulley with compressor flywheel.
Improper belt tension Readjust.
Pulley wobbles Replace the pulley and check for a damaged crankshaft or flywheel.
