TROUBLESHOOTING GUIDE
Possible Cause
Defective motor/pressure switch.
Check valve stuck in open position.
Possible defective safety relief valve.
Excessive tank pressure.
Blown gaskets.
Fittings are not tight enough.
Defective or rusted air tank.
Damaged inlet (reed) valve.
Pressure regulator knob is not turned
to high enough pressure.
Defective motor/pressure regulator
switch.
Restricted air intake filter.
Air leaks.
Hose or hose connections are too
small or long.
Air compressor is not large enough for
air requirement.
Restricted air intake filter.
Leaking (reed) valve.
Restricted pilot valve.
Low compression.
Restricted air intake filter.
Air compressor on unlevel surface.
Crankcase overfilled with oil.
Plugged oil dipstick vent.
Oil leaks.
Worn piston rings or scored cylinder.
Improper oil viscosity.
Water in oil due to condensation.
Condensation in air tank caused by
high level of atmospheric humidity or
air compressor is not running long
enough.
Possible Solution
Replace.
Replace check valve. DANGER — Do not disassemble the
check valve with tank pressurized. Open tank petcock valve
to allow air to escape from tank prior to servicing.
Operate safety relief valve manually by pulling on ring. If it
still leaks, it should be replaced.
Defective motor/pressure switch. Replace.
Replace blown gaskets and torque head bolts to 20 ft./lbs.
CAUTION — Replace head gasket with a new one each time
the head is removed to ensure proper sealing.
Tighten fittings where air can be heard escaping. Check
fittings with soapy water solution. DO NOT OVERTIGHTEN.
Air tank must be replaced. DO NOT ATTEMPT TO REPAIR
AIR TANK!
Contact Consumer Helpline at 1-800-423-3598.
Adjust pressure regulator knob to proper setting.
Replace.
Clean or replace the filter element.
Check for leaks by applying soap solution to all fittings and
connections. Bubbles will appear at leakage points. Tighen or
replace leaking fittings or connections as needed.
Replace with larger hose or connectors.
Check the accessory air requirement. If it is higher than the
CFM or pressure supply of the air compressor, you need a
larger air compressor.
Clean or replace the filter element.
Drain air tank and measure pump up time. Compare to
specifications. If lower, remove pump head and inspect valve
plate, valve seats, and valve reeds. Clean or replace as needed.
Clean or replace.
Low pressure may be due to worn piston rings and cylinder
walls. Inspect for excessive wear and replace worn parts as
needed.
Clean or replace air filter element.
Do not incline the air compressor more than 10 degrees in
any direction while running.
Drain oil. Refill to proper level with 30 weight non-detergent
air compressor oil
Clean and check breather for proper ventilation.
Repair.
Replace worn or damaged parts as needed.
Drain oil. Refill to proper level with 30 weight non-detergent
air compressor oil.
Change oil and move air compressor to a less humid
environment.
Drain tank after every use. Drain air tank more often in
humid weather and use an air line filter.
