OPERATION
BEFORE OPERATING YOUR NEW AIR COMPRESSOR please read manual
carefully
.
1 Check that all nuts and bolts are secure.
2. Make sure oil has been properly added to compressor.
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 pressure above that required at the air service
connection. The air inlet filter openings must be kept clear of obstructions, which could reduce air delivery of the
compressor.
Installation and Location
Locate the compressor in a clean, dry and well ventilated area. The compressor should be located 12 to 18
inches from walls or any other obstruction, which would interfere with airflow. Compressor should be located in a
temperature controlled area between 32" and 95" fahrenheit. Place the compressor on a firm, level surface. The
compressor is designed with heat dissipation fins which allow for proper cooling. Keep the fins (and
911 other parts which collect dust or dirt) clean. A clean compressor runs cooler and provides longer service. Do
not place rags, containers or other material on top of the compressor.
Connecting to Power Source
This air compressor is designed to operate on a properly grounded 120 volt, 60Hz, single phase, alternating
current (AC) power source with a fused 20 amp time delayed fuse or circuit breaker. It is recommended that a
qualified electrician verify the ACTUAL VOLTAGE at the receptacle into which the unit will be plugged and
confirm that the receptacle is properly fused and grounded. The use of the proper circuit size can eliminate
nuisance circuit breaker tripping while operating your air compressor.
Extension Cords
For optimum Air Compressor performance an extension cord should not be used unless
absolutely necessary. If necessary, care must be taken in selecting an extension cord appropriate for use with
your specific Air Compressor. Select aproperly grounded extension cord which will mate directly with the power
source receptacle and the Air Compressor power cord without the use of adapters. Make certain that the
extension cord is properly wired and in good electrical condition. Maximum length of extension cord should be 50
feet. Minimum wire size of extension cord should be 12 gauge.
