Thermal Overload Protector

The compressor motor is equipped with a thermal overload protector. If the motor
should overheat, the overload protector will shut the motor off. If this occurs,
turn the on/off lever to the off position and allow motor to cool for approximately
5 minutes.
NOTE: Tank pressure must be below 100 PSIG for the compressor to start.
Restart the compressor by moving on/off lever to the on position. If compressor
fails to start, check for blown fuses; the compressor may require more time to
cool. If the overload protector shuts down the motor frequently, it could be due
to low voltage.Common signs of low voltage are:
1. Motor does not get up to power or speed.
2. Fuses or circuit breaker activate when starting compressor.
3. Lights dim or remain dim when compressor is started.
4. Other motor operated appliances fail to operate property.
5. Too many motor operated appliances on same circuit.

Pressure Switch

The compressor is operated by an on - auto/off lever on
the side of the pressure switch. By turning the lever to
the "AUTO" position the compressor will start and stop
automatically within the settings of the pressure switch. The
pressure switch is factory adjusted to start the compressor
when the tank pressure drops below 100 PSIG and to
stop when tank pressure reaches 122 PSIG. To stop the
compressor, turn the lever clockwise to the "OFF" position.
Lever
(DO NOT STOP THE COMPRESSOR BY REMOVING THE
ELECTRICAL PLUG.) The on/off lever operates a valve which relieves pressure
from the compressor. If the lever is left on when the electric power is interrupted,
the compressor may have difficulty in starting under this pressure.

Operating Procedures

1. Make sure on/off lever is in the off position.
Before using air tools or accessories, check manufacturer's
WARNING:
maximum pressure rating. Maximum pressure rating must be above 122
PSIG.
2. Attach air hose and accessory to compressor.
(Remove orange pull plug first.)
3. Turn on/off lever to the on position and allow tank
pressure to build.
4. When the motor stops, it has reached cutout
attach air hose
pressure and the unit is ready for use.
