Operating Instructions and Parts List
Introduction (continued)
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 on this compressor. These
gauges read air pressure in pounds
per square inch (psi). The larger
gauge 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 small gauge
shows pressure in the tank indicating
compressor is building pressure
properly.

Installation
LOcatIOn
It is extremely important to use the
compressor in a clean, well ventilated
area where the surrounding air
temperature will not be more than
104°F.
A minimum clearance of 18 inches
between the compressor and a wall
is required because objects could
obstruct air flow.

air inlet near steam, paint spray,
sandblast areas or any other source
of contamination. This debris will
damage the motor.

1. This product is for use on a
nominal 120 volt circuit and has a
grounding plug that looks like the
plug illustrated in Figure 3. Make
sure the product is connected
to an outlet having the same
configuration 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.
