- A POTENTIAL HAZARD THAT WILL CAUSE SERIOUS INJURY OR LOSS OF LIFE.
DANGER:
- A POTENTIAL HAZARD THAT COULD CAUSE SERIOUS INJURY OR LOSS OF LIFE.
WARNING:
- A POTENTIAL HAZARD THAT MAY CAUSE MODERATE INJURY OR DAMAGE TO EQUIPMENT.
CAUTION:
WARNING:
1. RISK OF FIRE OR EXPLOSION. Never spray
flammable liquids in a confined area. It is normal for
the motor and pressure switch to produce sparks while
operating. If sparks come into contact with vapors from
gasoline or other solvents, they may ignite, causing
fire or explosion. Always operate the compressor in a
well-ventilated area. Do not smoke while spraying. Do
not spray where sparks or flame are present. Keep
compressor as far from spray area as possible.
2. RISK OF BURSTING. Rust can weaken the tank. Drain
the condensed water from the tank after each use to
reduce rusting. If a leak is detected in the tank, replace
the tank immediately. Do not weld, drill or modify the
air tank of this compressor. Welding or modifications
on the air compressor tank can severely impair tank
strength and cause an extremely hazardous condition.
Welding or modifying the tank in any manner will void
the warranty.
3. RISK OF ELECTRICAL SHOCK. A licensed electrician
in accordance with all local and national codes must

12. RISK TO BREATHING. Never directly inhale the
compressed air produced by a compressor. It is not
suitable for breathing purposes.
13. The power cord on this product contains lead, a
chemical known to the State of California to cause
cancer, and birth defects or other reproductive harm.
Wash hands after handling.
5. Protect the air hose and electric cord from damage and
puncture. Inspect them weekly for weak or worn spots,
and replace if necessary.
6. To reduce the risk of electric shock, do not expose to
rain. Store indoors.

ELECTRICAL POWER REQUIREMENTS
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding
plugs and 3-pole receptacles that accept the air compressor’s plug.
When using the air compressor at a considerable distance from
the power source, use an extension cord heavy enough to carry
the current that the compressor will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of power
and causing the motor to overheat. Use the chart provided below
to determine the minimum wire size required in an extension cord.
Only round jacketed cords listed by Underwriter’s Laboratories (UL)
should be used.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the air compressor outdoors, use an
extension cord that is designed for outside use. This is indicated by
the letters “W-A” on the cord’s jacket.
Before using an extension cord, inspect it for loose or exposed
wires and cut or worn insulation.
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk of
electric shock. This air compressor is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug.
The plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician. Improper
connection of the equipment-grounding conductor can result in a
risk of electric shock. The conductor with insulation having an outer
surface that is green with or without yellow stripes is the equipmentgrounding conductor. If repair or replacement of the electric cord
or plug is necessary, do not connect the equipment-grounding
conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in doubt
as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This air compressor is intended for use on a circuit that has an
outlet like the one shown in Figure 1. It also has a grounding pin
like the one shown.
This product must be grounded.
WARNING:
Keep the extension cord clear of the
working area. Position the cord so that it will not get caught on
lumber, tools, or other obstructions while you are working with
a power tool. Failure to do so can result in serious personal
injury.
WARNING:
Check extension cords before each use. If
damaged, replace immediately. Never use air compressor with
a damaged cord since touching the damaged area could cause
electrical shock resulting in serious injury.
NOTE: Use longer air hoses instead of long extension cords.
Your air compressor will run better and last longer.
ELECTRICAL CONNECTION
This air compressor is powered by a precision built electric
motor. It should be connected to a power supply that is 120 volts,
60 Hz, AC only (normal household current). Do not operate this
tool on direct current (DC). A substantial voltage drop will cause
a loss of power and the motor will overheat. If the air compressor
does not operate when plugged into an outlet, double check the
power supply.
SPEED AND WIRING
The no-load speed of this air compressor is approximately
26,000 rpm. This speed is not constant and decreases under a
load or with lower voltage. For voltage, the wiring in a shop is as
important as the motor’s horsepower rating. A line intended only for
lights cannot properly carry a power tool motor. Wire that is heavy
enough for a short distance will be too light for a greater distance. A
line that can support one power tool may not be able to support two
or three tools.

OVERVIEW
BASIC AIR COMPRESSOR COMPONENTS
Oilless air compressors are factory lubricated for life and do
not require any oil.
The basic components of the air compressor are the electric
motor, pump, control panel and tank.
The electric motor powers the pump. The electric motor is
equipped with an overload protector and an automatic reset. If the
motor becomes overheated, the overload protector will shut it down
to prevent damage to the motor. When the motor sufficiently cools,
it will automatically restart.
The pump compresses the air and discharges it into the tank.
The tank stores the compressed air.
The control panel of the compressor consists of the ON/OFF
button (A) and of the pressure regulator knob (B)
As compressed air is used and the pressure level in the
tank drops to the cut-in pressure, the control board restarts the
motor automatically, without warning, and the pump resumes
compressing air. The pressure regulator shuts down the motor
when the air pressure in the tank reaches the cut-out pressure.
