WATER WILL CONDENSE IN THE AIR TANK.  IF NOT
DRAINED, WATER WILL CORRODE AND WEAKEN
THE AIR TANK CAUSING A RISK OF AIR TANK RUP-
TURE.

11. After the water has been drained, close the drain cock or

drain valve.  The air compressor can now be stored.

NOTE

If drain cock valve is plugged, release all air
pressure.  The valve can then be removed,
cleaned, then reinstalled.

Units With External Brass Check Valve
Replacement

1.

Release all air pressure from air tank and unplug outfit.

2.

Remove shroud (if necessary).

3.

Loosen the top and bottom nuts and remove the outlet tube.

UNIT CYCLES AUTOMATICALLY WHEN POWER IS ON.  WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO
VOLTAGE SOURCES, COMPRESSED AIR OR MOVING PARTS.  PERSONAL INJURIES CAN OCCUR.  BEFORE
PERFORMING ANY MAINTENANCE OR REPAIR, DISCONNECT POWER SOURCE FROM THE COMPRESSOR AND
BLEED OFF ALL AIR PRESSURE.

Air Filter - Inspection and Replacement

Keep the air filter clean at all times.  Do not operate the compres-
sor with the air filter removed. 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. If it is dirty,
simply pull it out.  You may wash it with a mild detergent and
warm water, or replace it.

Safety Valve - Inspection

IF THE SAFETY VALVE DOES NOT WORK PROP-
ERLY, OVER-PRESSURIZATION MAY OCCUR,
CAUSING AIR TANK RUPTURE OR AN EXPLO-
SION.  DAILY 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
REPLACED WITH THE SAME TYPE OF VALVE.

Daily:

1.

Drain water from the air tank, any moisture separators
or transformers.

2.

Check for any unusual noise and/or vibration.

3.

Manually check safety valve to make sure of proper opera-

tion.

4.

Inspect air filter, replace if necessary.

5.

Inspect air lines and fittings for leaks; correct as

necessary.

Each Year of Operation or if a Problem is Suspected:

Check condition of air compressor pump intake and exhaust
valves. Replace if damaged or worn out.

ROUTINE  MAINTENANCE  SCHEDULE

To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should be prepared and
followed. The following routine maintenance schedule is geared to an outfit in a normal working environment operating on a daily
basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications
will depend upon the hours of operation and the working environment. Compressor outfits in an extremely dirty and/or hostile
environment will require a greater frequency of all maintenance checks.

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 strong
solvent.

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 (if removed).

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/or is running.
