Northern Industrial Tools 2 HP / 4 GALLON AIR COMPRESSOR instruction

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. 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 all 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 a properly 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.

Attaching an Air Hose

Your Air Compressor is supplied with a 1/4" Quick Disconnect Air Chuck. Once you have correctly installed the Air Chuck (See Installing the Air Chuck on p.4) your compressor will be ready to accept air hoses equipped with 1/4" male air couplers.

Note: Use only air hoses rated for use with 115psi air pressure or higher.

To install an air hose, equipped with a 1/4" male coupler:

1. Pull back on Air Chuck outer sleeve to allow coupler to be fully inserted into Air Chuck.

2. Insert coupler into Air Chuck.

3. Release outer sleeve of Air Chuck.

4. Verify that air hose is securely connected to Air Chuck by pulling lightly on air hose.

(See Figure 5)

Adjusting the Air Pressure

Your Air Compressor is supplied with an Air Pressure Regulator. This Regulator adjusts the air pressure.

To increase air pressure, turn Air Regulator clockwise.

To decrease air pressure, turn Air Regulator counterclockwise.

(See FigureFigure6) 6. Adjusting the Air Pressure

Cold Weather Starting

Temperatures below freezing (32°F) cause the metal parts of your Air Compressor to contract and that makes starting more difficult. To assist the Air Compressor in starting in cold weather, follow
