AIR COMPRESSOR

test run

before using the air compressor for the first time, complete a test

run as follows:

1.

Turn the power switch to the OFF position. Plug the power

supply cord into a power supply socket. Start the air

compressor by turning the power switch to the ON position.

The pressure gauge reading will slowly rise as pressure

increases inside the air tank. When the gauge reading reaches

120 -125 PSI, the pressure switch will automatically turn the

power off. This indicates the compressor is working normally. 

2.

daily operation

Starting the compressor:

1.

Turn the power switch to the OFF position.

2.

Attach the air hose to the 1/4” (universal / Industrial) coupler.

3.

Close the drain valve. 

4.

Plug the power supply cord into a power supply socket.

5.

Turn the power switch to the ON position.

6.

Let the motor run and tank fill until motor turns off.

7.  

Operate air tool normally. 

8.

To regulate the air to the air hose. have the air compressor 

and air tool both turned on and running. Turn the regulator 
knob to the right to increase the pressure and to left to 
decrease the air pressure to the hose and air tool..

Shutting down the compressor:

1.

Turn the power switch to the OFF position.

2.

unplug the power supply cord.

3.

Reduce the pressure in the air tank through the air supply

hose.

Air compressor surfaces become hot during 
operation.

DO NOT touch hot surfaces, because they can cause 
severe burns.

Do not touch the air compressor’s cylinder head. 
During operation, the cooling fins of the cylinder 
head and delivery pipe become hot.

Allow the air compressor to cool before touching it.

DO NOT place a storage cover on the unit during 
operation. Only place a cover on the air compressor 
after it has thoroughly cooled down.

FIRE

HOT SURFACE

WARNING

Flying objects can cause injury to the eyes, head and 
other parts of the body.

Air-powered equipment and power tools are capable 
of propelling items (metal chips, fasteners and 
particulates) at high speed into the air and could 
result in injury.

Always wear approved head and eye protection.

Never point the air stream at any part of your body, 
or at another person or animal.

When operating the air compressor, make sure all 
other people and animals maintain a safe distance.

Do not move the air compressor when the air tank is 
under pressure. 

Never use the air hoses to pull or move the air 
compressor.

Keep the air compressor on a flat surface.

WARNING

FLYING OBJECTS

note: 

If the Air Compressor is not working properly, the

pressure gauge will indicate that there is a decrease in

pressure in the air tank. If there is an air leak from the

compressor the pressure in the air tank decreases, the

pressure switch resets and the motor automatically turns

back on.
If you detect an air leakage, turn the power switch to the

Off position, release the air from the tank by pulling on

the safety valve. unplug the power supply cord and contact

Customer Support for Assistance.

Turn the power switch to the Off position, unplug the power

supply cord and release the air from the drain valve.

At this point proceed to the next step (daily operations)

starting the air compressor to continue to use.
