Repairs to the cord set or plug
MUST be made by a qualified

electrician.

11_ ENG D27312

Extension Cords

Using extension cords is not
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

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
12 gauge (AWG) or larger. (Wire

size increases as gauge number
decreases. 10 AWG and 8 AWG

may also be used. DO NOT USE
14 OR 16 AWG.)

Voltage and Circuit Protection

Refer to the Parts Manual for the

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.

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 TankPressure Gauge Outlet

Switch Pressure

On/Auto/Off

Switch

Safety Valve

Description of Operation

Become familiar with these controls
before operating the unit.

On/Auto/Off Switch: Turn this switch
ON 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).
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.

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.

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.

13_ ENG

Gauge

D27312

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.

Pressure Release Valve: The
pressure release valve located on the

side of the pressure switch, is
designed to automatically release
compressed air from the compressor

head and the outlet tube when the air
compressor reaches "cut-out"

pressure or is shut off. The pressure
release valve allows the motor to

restar_ freely. When the motor stops
running, air will be heard escaping

from this valve for a few seconds.
No air should be heard leaking when

the motor is running or after the unit
reaches "cut-out" pressure.

Motor Overload Protector: The
motor has an automatic reset thermal

overload protector. If the motor
overheats for any reason, the
overload protector will shut off the

motor. The motor must be allowed to
cool down before restarting. The

compressor will automatically restart
after the motor cools.

How to Use Your Unit

How to Stop:

1. Set the On/Auto/Off leverto
"OFF".

Before First Start-up

Risk of Unsafe
Operation. Serious

damage may result if the following
break-in instructions are not
