Installation (Continued)
Make sure the product is connected
to an outlet having the same
confi guration as the plug. This
product must be grounded. In the
event of an electrical short circuit,
grounding reduces risk of electrical
shock by providing an escape wire
for electric current. This product
is equipped with a cord having a
grounding wire with an appropriate
grounding plug. Plug must be
plugged into an outlet that is
properly installed and grounded in
accordance with all local codes and
ordinances.
Overheating,
short
circuiting and fi re
damage will result from inadequate
wiring.
LUBRICATION
THIS UNIT IS SHIPPED
WITHOUT OIL!
Follow lubrication instructions before
operating compressor.
Use oil shipped with the compressor.
Do not use regular automotive oil
such as 10W-30.
Additives in regular
motor oil can cause valve deposits and
reduce pump life. For maximum pump
life, drain and replace oil after the first
hour of run time.
The compressor pump takes
approximately 175mL (6 oz.) of oil. The
sight glass, located on the crankcase
portion of the pump, is used to
determine proper oil level. Fill the
crankcase with oil until the level is in
the middle of the sight glass. Avoid
overfilling by adding oil gradually and
checking the oil level with the sight
glass several times. Add enough oil to
reach the “max” level on the sight glass.
Proper oil level is illustrated in Figure 3.
Operation
BEFORE FIRST START-UP
BREAK-IN PROCEDURE
(Complete this procedure before using
compressor for the first time. Once
completed, it is not necessary to repeat.)
1. Open drain valve located on bottom
of tank.
2. Turn
AUTO / OFF
switch to
OFF
position.
3. Plug in power cord.
4. Turn
AUTO / OFF
switch to
AUTO
position and run compressor for 30
minutes.
5. Turn
AUTO / OFF
switch to
OFF
position.
6. Unplug power cord.
7. Close drain valve.
The compressor is now ready for use.
OPERATING PROCEDURE
1. Turn switch to
OFF
position and plug
in power cord.
2. Turn regulator knob
counterclockwise to close air flow.
3. Turn switch to
AUTO
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.
6. Adjust regulator to proper pressure
for tool or tire. Operate tool per
instructions.
As air is depleted from the tank by
use of a tire chuck, tool, etc., the
compressor will restart automatically
at its preset “cut-in” pressure. When
a tool is being used continuously,
the compressor will cycle on and off
automatically.
7. Turn switch to
OFF
position, unplug
power cord and drain tank of air
when finished using compressor.
CYCLING OF COMPRESSOR
In the
AUTO
position, the compressor
pumps air into the tank. When a
shut-off (preset “cut-out”) pressure is
reached, the compressor automatically
shuts off.
If the compressor is left in the
AUTO
position and air is depleted from the
tank by use of a tire chuck, tool, etc.,
the compressor will restart automatically
at its preset “cut-in” pressure. When
a tool is being used continuously,
the compressor will cycle on and off
automatically.
In the
OFF
position, the pressure switch
cannot function and the compressor
will not operate. Make sure switch
is in
OFF
position when connecting
or disconnecting power cord from
electrical outlet.
Maintenance
Disconnect, tag and lock out
power source, then release
all pressure from the system
before attempting to install, service,
relocate or perform any maintenance.
Check compressor often for any visible
problems and follow maintenance
procedures each time compressor is
used.
ASME SAFETY VALVE
Do not remove or
attempt to adjust
the safety valve!
Check the safety valve by performing
the following steps:
1. Plug the compressor in and run until
shut off pressure is reached.
2. Wearing safety glasses, pull the
ring on the safety valve to release
pressure from compressor tank. Use
your other hand to defl ect fast-
moving air from being directed
toward your face.

Use of an extension cord may cause excess
heat to motor. This could lead to tripped
breaker (at electrical panel) or tripped
thermal overload (on compressor motor).
If this occurs, eliminate extension cord and
plug compressor directly into electrical
outlet. Avoid using extension cords; use
longer air hose(s) instead.
