Problem Encountered Possible Cause Possible Solution
Insufficient pressure at air
tool or air accessory:
Air compressor not making
enough air:
Excessive oil consumption:
Oil has milky appearance:
Moisture in discharge air:
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.
Adjust pressure regulator knob to proper setting.
Replace.
Clean or replace the filter element.
Check for leaks by applying soap solution to all fit-
tings and connections. Bubbles will appear at leak-
age points. Tighen or replace leaking fittings or con-
nections 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 compres-
sor, 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, vlave seats, and vlave 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.
