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 Lever
when tank pressure reaches 125 PSIG. To stop the
compressor, turn the lever clockwise to the “OFF” position. (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.
WARNING:
Before using air tools or accessories, check manufacturer’s
maximum pressure rating. Maximum pressure rating must be above
125 PSIG.
2. Turn on/off lever to the on position and allow tank pressure to build.
3. When the motor stops, it has reached cutout pressure and the unit is
ready for use.
NOTE:
When using an accessory or air tool, pressure in the storage tank
decreases. When it reaches a certain low level (cut-in pressure) the motor
will automatically restart and raise the pressure in the storage tank.
4. To shut down compressor, simply move on/off lever to the off position.
5. Allow compressor to cool.
6. Drain storage tank (see Storage Tank in Maintenance Section).
