Operation
DEFINITION OF TERMS
ON/OFF Switch ( I / O ) - Push switch to
the ON ( I ) position to turn compressor
on. Push switch to the OFF ( O ) position
to turn compressor off. This switch
should be in the OFF ( O ) position
when connecting / disconnecting power
cord from electrical outlet or when
changing tools.
Pressure Switch (located internally)-
When the compressor is turned ON,
this switch will shut compressor off
automatically when tank pressure
reaches maximum shut-off / cut-out
pressure. If compressor remains on and
air is depleted from tank, this switch
will allow compressor to automatically
restart at the restart / cut-in pressure.
Regulator - The regulator controls the
amount of air pressure released at the
hose outlet. Turning the regulator knob
clockwise (to the right) will increase air
pressure at the outlet. Turning the knob
counter-clockwise (to the left) will lower
air pressure to the outlet. Turning knob
fully counter-clockwise will shut off flow
of air completely.
Pressure Gauges - There are two
gauges located next to the regulator.
These gauges read air pressure in
pounds per square inch (psi). The
gauge on the right shows pressure at
the outlet. Make sure this gauge reads
ZERO (by adjusting the regulator)
BEFORE changing air tools or
disconnecting hose from outlet. The
gauge on the left shows pressure in the
tank indicating compressor is building
pressure properly.

ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Handle - Designed to move the
compressor.
Drain Valve - This valve is located on
the bottom of the tank. Use this valve
to drain moisture from the tank daily to
reduce the risk of corrosion.
Motor Protection - If the unit is over
worked, a thermal limiter will shut unit
off. If this happens, switch unit to OFF,
wait 30 minutes to cool, turn ON again
to resume work.
LUBRICATION
This is an oilless product and DOES NOT
require lubrication to operate.
BEFORE FIRST STARTUP BREAK-IN
PROCEDURE
(Complete this procedure before using
compressor for the first time. Once
completed, it is not necessary to repeat.)
1. Turn regulator knob fully clockwise
(to the right) to open air flow.
2. Do not attach a hose or any other
fitting to the compressor.
3. Turn ON/OFF switch to OFF position.
4. Plug in power cord.
5. Turn ON/OFF switch to ON position.
Allow compressor to run for 5
minutes.
6. Turn ON/OFF switch to OFF position.
7. Unplug power cord.
OPERATING PROCEDURE
1. Turn switch to OFF ( O ) position and
plug in power cord.
2. Turn regulator knob
counterclockwise to close air flow.
3. Turn switch to ON ( I ) position.
4. Compressor will build to maximum
pressure and shut off.
5. With hose attached to outlet of
compressor, attach tire chuck or
other tool to open end of hose.
