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, remove the screws and filter retainer. Pull out
the filter, replace with new.

Oil - Checking and Changing

Overfilling with oil will cause premature
compressor failure. Do not overfill.
Check oil level in the crankcase daily. The oil level should
be even with the top of the fill hole and must not be
allowed to be lower than 3/8" from the top (6 threads) at
any time. It is recommended that the oil be changed after
every 100 hours of operation. To drain the oil, remove the
oil drain plug and collect the oil in a suitable container. Be
sure to replace the plug securely before adding new oil.
Use a special compressor oil such as Sears 9-16426 or
SAE-20-20W SF motor oil. (Crankcase oil capacity is 16
fluid ounces.) Under extreme winter conditions use 10
weight oil.

Air Tank - Draining Water

WATER WILL CONDENSE IN THE AIR
TANK. IF NOT DRAINED, THE WATER WILL
CORRODE AND WEAKEN THE AIR TANK
CAUSING A RISK OF AIR TANK RUPTURE.
Water should be drained from the air tank after each use.
Operate the unit to apply 15-20 PSIG and open the drain
cock. Continue operating unit until all moisture is re-
moved from the air tank. Close the drain cock tightly.
NOTE
If drain cock valve is clogged, release air
pressure in air tank. The drain cock valve
can then be removed, cleaned and rein-
stalled.
Check Valve - Inspection and
Replacement
Remove the check valve for inspection or replacement if
air tank pressure will not build up. Use the following
procedure to inspect, clean or replace the check valve.
1. Release air pressure from the air tank.
2. Loosen the top and bottom nuts and remove the
outlet tube.
3. Unscrew the check valve (turn counterclockwise)
using a 7/8" diameter 1/2" socket wrench.
4. 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.

Motor

The motor has a 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. De-energize power supply. To restart,
depress the reset button located on the end of the motor
and energize the power supply.

Belt - Replacement

SERIOUS INJURY OR DAMAGE MAY OCCUR IF PARTS OF
THE BODY OR LOOSE ITEMS GET CAUGHT IN MOVING
PARTS. NEVER OPERATE THE COMPRESSOR WITH THE
BELT GUARD REMOVED. THE BELT GUARD SHOULD BE
REMOVED ONLY WHEN THE POWER TO THE COMPRES-
SOR IS DISCONNECTED.
The motor is mounted on an adjustable motor base.
To replace belt:
1. Turn off and lock out power source.
2. Remove screws from the back of the belt guard.
3. Loosen the four motor mounting screws.
4. Slide the motor toward the compressor pump.
5. Remove belt and replace.

IF THE SAFETY VALVE DOES NOT WORK
PROPERLY OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE
OR 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 REPLACED WITH
THE SAME TYPE OF VALVE.
NOTE
If the overload protector shuts the motor
off frequently, check for a possible voltage
problem. Low voltage can also be sus-
pected when:
1. the motor does not get up to full power
or speed;
2. fuses blow out when the motor is
started;
3. lights dim when motor is started and
remain dim while it is running.
