OPERATION

BEFORE OPERATING YOUR NEW AIR

COMPRESSOR please check the following points

carefully:

1 Check that all nuts and bolts are secure.

2. Make sure oil has been properly added to

compressor. (See Installing Oil and Oil Breather

Cap section.)

Initial Start-Up Procedure

1. Open the Air Tank Drain Valve to permit air to

escape, preventing air pressure buildup in the

air tank.

2. Run the compressor for a minimum of 20

minutes in this “no-load” position to lubricate the

piston and bearings.

3. Close Air Tank Drain Valve. Your compressor is

ready for use.

Depending on the CFM draw of the tools being

operated, your new Air Compressor can be used for

operating paint sprayers, air tools, grease guns,

airbrushes, caulking guns, abrasive blasters, tire &

plastic toy inflation, spraying weed killer and

insecticides, etc. Proper adjustment of the Air

Pressure Regulator is necessary for all of these

operations. Refer to the air pressure specifications

provided with the tool you are using.

General Overview

To compress air, the piston moves up and down in

the cylinder. On the down stroke air is drawn in

through the valve inlet. The discharge valve remains

closed. On the upstroke of the piston air is

compressed. The inlet valve closes and air is forced

out through the discharge valve, through the check

valve, and into the air tank. Working air is not

available until the compressor has raised the tank
