1. The air compressor must be turned off.
2. Disconnect compressor from the power source.
3. Open tank drain to bleed off all air pressure before attempting any maintenance
or repair.
4. Allow compressor to fully cool before attempting any maintenance or repair.
Check the air compressor frequently for any visible problems and follow mainte-
nance procedures each time the compressor is used.

Moisture is a normal by-product of compressing air. As the moisture builds during
compressor use, it can be carried though the air hose. When using paint spray gun
or sandblasting gun, the use of a special filter to remove moisture from the air line
is highly recommended. Moisture in the compressed air will cause water spots in
paint jobs and cause blasting media to clog the sandblasting gun.

PROBABLE CAUSE:
Power cord not plugged in.
Motor/Pressure switch in
OFF position
Wrong gauge wire or length
of extension cord.
Air tank pressure exceeds
motor/pressure switch
"cut-in" pressure.
SOLUTION:
Plug cord into grounded outlet.
Move switch to AUTO position.
Check chart in instruction manual for proper
gauge wire and cord length.
Motor will start automatically when air tank
pressure drops below "cut-in" pressure of
motor/pressure switch.

PROBABLE CAUSE:
Air compressor is incorrectly
sized.

PROBABLE CAUSE:
Fittings are not tight enough.

PROBABLE CAUSE:
Pressure regulator knob is
not turned to high enough
pressure.
Defective motor ON/OFF
switch.
Air leaks.
Hose or hose connections
are too small or long.
Air compressor is not large
enough for air requirement.
M M O O I I S S T T U U R R E E I I N N D D I I S S C C H H A A R R G G E E A A I I R R : :
PROBABLE CAUSE:
Condensation in air tank
caused by high level of
atmospheric humidity or air
compressor is not running
long enough.
SOLUTION:
Limit the air pressure to the capacity of the air
compressor. Either use a smaller tool or a
larger air compressor.
SOLUTION:
Tighten fittings where air can be heard
escaping. Check fittings with soapy water
solution. DO NOT OVERTIGHTEN.
SOLUTION:
Adjust pressure regulator knob to proper setting.
Replace.
Check for leaks by applying soap solution to
all fittings and connections. Bubbles will
appear at leakage points. Tighten 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.
SOLUTION:
Drain tank after every use. Drain air tank
more often in humid weather and use
an air line filter.
