This manual contains information that relates to PROTECTING
PERSONAL SAFETY and PREVENTING EQUIPMENT PROBLEMS. It

is very important to read this manual carefully and understand
it thoroughly before using the product. The symbols listed
below are used to indicate this information.

DANGER!

Potential hazard that will result in serious injury or loss of life.

WARNING! Potential hazard that could result in serious injury or loss of life.

CAUTION!

Potential hazard that may result in moderate injury or damage to equipment.

IMPORTANT! Installation, operation or maintenance informa tion that is important but

not hazard related.

Safety Advice

DANGER!

1. RISK OF FIRE OR EXPLOSION. Do not spray a flammable or combustible liquid or

paint near sparks, flames, pilot lights or in a confined area. The spray area must be

well-ventilated. Keep compressor at least 20’ (6 m) away from spray area. Do not
carry and operate the compressor or any other electrical device near the spray area. Never smoke
when spraying. Use a minimum of 25’ (7.6 m) of hose to connect a spray gun to the compressor.

2.

RISK OF ELECTRIC SHOCK. Do not expose to rain. Store indoors. Hazardous voltage.

Disconnect from power source before servicing. Compressor must be grounded. Do

not use grounding adaptors.

3.

RISK OF BURSTING. Make sure the regulator is adjusted so that the compressor outlet

pressure is set lower than the maximum operating pressure of the spray gun or tool.

Before starting the compressor, pull the ring on the safety valve to make sure the valve

moves freely (see diagram on page 17). Drain water from tank after each use. Do not

weld or repair tank.

SAFETY GUIDELINES

4. RISK OF PERSONAL INJURY. Never spray compressed air or ma terial at self or others.

5. RISK OF BURSTING. Check the maximum pressure rating in the manual or

identification label. The compressor outlet pressure must be regulated so that it does
not exceed the maximum pressure rating. Relieve all pressure in the hose before
removing or attaching accessories.

6.

RISK OF BURSTING. Do not adjust the pressure switch or safety valve for any reason.
They have been preset at the factory for this compressor’s maximum pressure.
Tampering with the pressure switch or the safety valve may cause personal injury or
property damage.

7.

RISK OF BURNS. The pump and the manifold generate high temperatures. In order to
avoid burns or other injuries, do not touch the pump, the manifold or the transfer tube
while the compressor is running. Allow the parts to cool down before handling or
servicing. Keep children away from the compressor at all times.

8.

RISK TO BREATHING. Be certain to read all labels when you are spraying paints or
toxic materials, and follow all safety instructions. Use a respirator mask if there is a
chance of inhaling anything you are spraying. Also, NEVER directly inhale the air
produced by a compressor.

9. RISK OF EYE INJURY. Wear ANSI Z87.1 approved safety goggles when using an air

compressor. Do not point any nozzle or sprayer toward a person or any part of the
body. Serious injury may occur if the spray penetrates the skin.

WARNING!

1. Pull the pressure safety valve ring every day in order to ensure that

the valve is functioning properly.

2. The compressor must be located in a well-ventilated area for
cooling, and must be a minimum of 12” (31 cm) away from the
nearest wall.

3. Protect the air hose and the power cord from damage and puncture. Inspect them for weak or worn
spots every week, and replace them if necessary.

4. Always wear hearing protection when using an air compressor. Failure to do so may result in
hearing loss.

5. Do not carry the compressor while it is running.

SAFETY GUIDELINES

6. Do not operate the compressor if it is not in a stable position.

7. Do not operate the compressor on a rooftop or an elevated position that could allow the unit to fall

or be tipped over.

8. Always replace a damaged gauge before operating the unit again.

Extension cords

As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using
extension cords with inadequately sized wire causes a serious drip in voltage, resulting in loss of power
and possible product damage. Refer to the table here to determine the required minimum wire size.

* Based on limiting the line voltage drop to five volts at 150% of the rated amperes.

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a
14-gauge cord can carry a higher current than a 16-gauge cord. When using more than one extension
cord to make up the total length, be sure each cord contains at least the minimum wire size required.

Guidelines for using extension cords

•

•

• your

are

your

If you using an extension cord outdoors, be sure it is marked with the

"W-A" ("W" in

Canada) to indicate it is acceptable for outdoor use.

Ensure extension cord is properly wired and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a qualified technician before using it.

Protect extension cords from sharp objects, excess heat and damp or wet areas.

A. ELECTRIC MOTOR: The motor is used to power the pump. It is equipped with at thermal overload

protector. If the motor overheats for any reason, the thermal overload protector will shut it do wn in
order to prevent the motor from being damaged.

B. AIR COMPRESSOR PUMP: The pump compresses the air and discharges it into the tank via the

piston that moves up and down in the cylinder.

C. PRESSURE SWITCH: This switch turns the compressor on and off. It is operated manually and

when it is in the ON position, it allows the motor to start if the pressure in the air tank is below the
factory set cut-in pressure, and allows the motor to stop if the pressure in the air tank reaches the
factory set cut-out pressure. Be sure to set this switch to the OFF position when the compressor is
not being used and before unplugging the compressor.

D. SAFETY VALVE: This valve is used to prevent system failure by draining pressure from the system

when it reaches a preset level if the pressure switch has not shut down the motor. It will pop open
automatically, or it can be activated manually by pulling the ring on the valve.

E. AIR PRESSURE REGULATOR: The regulator is used to adjust the pressure inside the line to the

tool that is being used. Turn the knob clockwise to increase the pressure and counter-clockwise to
decrease the pressure.

[

WARNING! Do not exceed the tool’s maximum working pressure.

F. T ANK PRESSURE GAUGE: The gauge measures the pressure level of the air that is stored in the

tank. It cannot be adjusted by the operator and it does not indicate the pressure inside the line.

G. OUTLET PRESSURE GAUGE: The gauge measures the regulated outlet pressure.

H. AIR OUTLET: The outlet is connected to the 1/4” (6.4 mm) NPT air hose.

I. AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank after the

compressor is shut off.

[

WARNING! Do not attempt to open the drain valve when there is more than

10 PSI of air pressure in the tank.
