Portable Air Compressors
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.
improper use of
grounding plug can
result in a possible risk of electrical shock!
NOTE: Do not use grounding adapter.
2. If repair or replacement of cord or
plug is necessary, do not connect
grounding wire to either flat blade
terminal. The wire with insulation
having an outlet surface that is green
with or without yellow stripes is the
grounding wire.
3. Check with a qualified electrician or
serviceman if grounding instructions
are not completely understood, or
if in doubt as to whether product is
properly grounded. Do not modify
plug provided; if it will not fit outlet,
have proper outlet installed by a
qualified electrician.
Never connect
green (or green and
yellow) wire to a live terminal.
ExTENSION CORDS
To avoid loss of
power and
overheating, it is better to use
additional air hose instead of extension
cords to reach work area.
1. Use only a 3-wire extension cord
that has a 3-blade grounding plug,
and a 3-slot receptacle that will
accept plug on product.
2. Make sure extension cord is in good
condition, and heavy enough to
carry current product will draw. An
undersized cord will cause a drop in
line voltage resulting in loss of power
and overheating.
3. Table below shows correct size to
use depending on cord length and
nameplate ampere rating. If in doubt,
use next heavier gauge.
NOTE: The smaller the gauge number,
the heavier the cord.
4. This product is for use on a nominal
120 volt circuit and has a grounding
plug that looks like plug illustrated
in Figure 4. Make sure that product is
connected to an outlet having same
configuration as 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.
Do not use adapter
with this product!
Operation
• Pressure Switch - ON/OFF Switch
(Figure 5) - In the ON position, the
compressor shuts off automatically
when tank pressure reaches the
maximum preset pressure. In the
OFF position, the compressor will
not operate. This switch should be in
the OFF position when connecting
or disconnecting the power cord
from the electrical outlet or when
changing air tools.
• Regulator - The regulator controls
the amount of air pressure released
at the hose outlet.
• ASME Safety Valve - This valve
automatically releases air if the
tank pressure exceeds the preset
maximum.
• Exhaust Tube - This tube carries
compressed air from the pump to
the check valve. This tube becomes
very hot during use. To avoid the
risk of severe burns, never touch
the exhaust tube.
• Check Valve - A one-way valve
that allows air to enter the tank, but
prevents air in the tank from flowing
back into the compressor pump.
• Handle - Designed to move the
compressor.
• Drain Valve - This valve is located on
the side of the tank. Use this valve to
drain moisture from the tank daily to
reduce the risk of corrosion.
Drain liquid from
tank daily.
Reduce tank pressure below 10 psi, then
drain moisture from tank daily to avoid
tank corrosion. Drain moisture from
tank by opening the drain valve located
underneath or on the side of the tank.
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. Turn regulator knob fully clockwise
(to the right) to open air flow and
open drain valve.
2. Turn ON/OFF switch to OFF position.
3. Plug in power cord.
4. Turn ON/OFF switch to ON position
and run compressor for 30 minutes.
5. Turn ON/OFF switch to OFF position.
6. Unplug power cord.
The compressor is now ready for use.

MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air
compressor pump. When humidity is high or when a compressor is in continuous use
for an extended period of time, this moisture will collect in the tank. When using a
paint spray or sandblast gun, this water will be carried from the tank through the
hose, and out of the gun as droplets mixed with the spray material.
IMPORTANT: This condensation will cause water spots in a paint job, especially
when spraying other than water based paints. If sandblasting, it will cause the sand
to cake and clog the gun, rendering it ineffective. A filter in the air line, located as
near to the gun as possible, will help eliminate this moisture.
