recommended. The use of extension
cords will cause voltage to drop
resulting in power loss to the motor
and overheating.
Instead of using an extension cord,
increase the working reach of the
air hose by attaching another length
of hose to its end. Attach additional
lengths of hose as needed.
If an extension cord must be used,
be sure it is:
• a 3-wire extension cord that has
a 3-blade grounding plug, and a
3-slot receptacle that will accept
the plug on the product
in good condition
no longer than 50 feet

voltage and minimum branch circuit
requirements.
_Risk of Unsafe
Operation. Certain
air compressors can be operated
on a 15 amp circuit if the following
conditions are met.
1. Voltage supply to circuit must
comply with the National
Electrical Code.
2. Circuit is not used to supply any
other electrical needs.
3. Extension cords comply with
specifications.
4. Circuit is equipped with a
15 amp circuit breaker or 15
amp time delay fuse. NOTE: If

Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.

Pressure Gauge
Safety
Valve
Body
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Switch: Turn this switch
"ON/AUTO" to provide automatic
power to the pressure switch and
"OFF" to remove power at the end of
each use.
Pressure Switch: The pressure
switch automatically starts the
motor when the air tank pressure
drops below the factory set "cut-in"
pressure. It stops the motor when the
air tank pressure reaches the factory
set "cut-out" pressure.
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "cut-out"
setting).
N000317 12-ENG
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air
pressure available at the outlet side
of the regulator. This pressure is
controlled by the regulator and is
always less than or equal to the tank
pressure.
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator: Controls the air pressure
shown on the outlet pressure
gauge. Pull the knob out and turn
clockwise to increase pressure
and counterclockwise to decrease
pressure. When the desired pressure
is reached push knob in to lock in
place.
Universal Quick-Connect Body:
The universal quick-connect body
accepts the three most popular styles
of quick-connect plugs- Industrial,
automotive (Tru-flate), and ARO. One
hand push-to-connect operation
makes connections simple and easy.
Drain Valve: The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
Drain
Valve
Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart of
this cooling system is an engineered
fan. It is perfectly normal for this fan
to blow air through the vent holes
in large amounts. You know that the
cooling system is working when air is
being expelled.
Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the
air outlet.
Check Valve: When the air
compressor is operating, the check
valve is "open", allowing compressed
air to enter the air tank. When the
air compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure to remain inside
the air tank.
How to Use Your Unit
Before Starting
Break-in Procedure
_Risk of Unsafe
Operation. Serious
damage may result if the following
break-in instructions are not
closely followed.
This procedure is required before the
