UNIT CYCLES AUTOMATICALLY WHEN POWER IS ON. WHEN DOING MAINTENANCE, YOU MAY BE

Air Filter - Inspection

NOTE

Keep the air filter clean at all times. Do not
operate the compressor with the air filter re-
moved.

A dirty air filter will not allow the compressor to operate at
full capacity. Before you use the compressor, check the
air filter to be sure it is clean.

To remove and clean (wash in mild detergent) or replace
the foam air filter, compress the rear slotted end of each
of the two pins holding filter in place and pull pin forward
releasing the filter itself. To reinstall a clean filter, place in
position and push retaining pins into holes securing filter.

NOTE: 

Wire support screen supplied in the replacement

parts kit, to be positioned behind the foam filter, is not
required on this 3/4 HP model.

Check Valve - Replacement

1. Release all air pressure from air tank and unplug

outfit.

2. Remove shroud.

3. Loosen the top and bottom nuts and remove the

outlet tube.

4. Remove the pressure release tube and fitting.

5. Unscrew the check valve (turn counterclockwise)

using a socket wrench.

6. Check that the valve disc moves freely inside the

check valve and that the spring holds the disc in the
upper, closed position. The check valve may be
cleaned with a solvent, such as paint and varnish
remover.

7. Apply sealant to the check valve threads. Reinstall

the check valve (turn clockwise).

8. Replace the pressure release tube and fitting.

9. Replace the outlet tube and tighten top and bottom

nuts.

10. Replace the shroud.

Safety Valve - Inspection

IF THE SAFETY VALVE DOES NOT WORK
PROPERLY, OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE OR
AN EXPLOSION. OCCASIONALLY PULL THE
RING ON THE SAFETY VALVE TO MAKE SURE
THAT THE SAFETY VALVE OPERATES
FREELY. IF THE VALVE IS STUCK OR DOES
NOT OPERATE SMOOTHLY, IT MUST BE RE-
PLACED WITH THE SAME TYPE OF VALVE.

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 re-start 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.
