Water will
condense in the air
tank. If not drained, water will
corrode and weaken the air tank
causing a risk of air tank rupture.
6. After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve can
then be removed, cleaned, the
reinstalled.
Air Filter - Inspection and
Replacement
Hot surfaces. Risk
of burn.
Compressor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
A dirty air filter will not allow the
compressor to operate at full
capacity. Keep the air filter clean at
all times.
1. Remove the air filter cover.
2. Remove the air filter and make
sure it is clean.
IMPORTANT: Do not operate the
compressor with the air filter
removed.
3. If dirty, rinse air filter with warm
water and squeeze dry.
4. Replace air filter and air filter
cover.

Motor
The motor has an automatic reset
thermal overload protector. If the
motor overheats for any reason, the
overload protector will shut off the
motor. The motor must be allowed to
cool down before restarting. The
compressor will automatically restart
after the motor cools.
If the overload protector shuts the
motor off frequently, check for a
possible voltage problem. Low
voltage can also be suspected when:
1. The motor does not get up to full
power or speed.
2. Fuses blow out when starting
the motor; lights dim and remain
dim when motor is started and is
running.
Air Compressor Pump Intake
and Exhaust Valves
Once a year have a Trained Service
Technician check the air compressor
pump intake and exhaust valves.
NOTE: If the air filter is extremely
dirty it will need to be replaced. Refer
to the “Repair Parts” for the correct
part number.
Inspect Air Lines and Fittings
for Leaks
1. Turn the air compressor on to
inspect for air leaks.
2. Apply a soap solution to all air
line fittings and
connections/piping.
3. Correct any leaks found.
IMPORTANT: Even minor leaks can
cause the air compressor to
overwork, resulting in premature
breakdown or inadequate
performance.
