Air Compressor Components Details

  • On/Off Switch – Rotate the On/Off Switch lever from “Off” to “Auto” to send automatic power to the compressor motor. As long as this switch is in the “Auto” position, the air compressor will automatically refill when the tank pressure drops below a certain limit. Rotate the On/Off Switch lever from “Auto” to “Off” after each use.
  • Safety Valve –The safety valve must be checked for functionality before each use. Simply pull on the ring with your finger to ensure the valve moves freely. The safety valve will automatically let air out of the tank if the tank pressure exceeds cut-off pressure (120PSI).
  • Check Valve – The check will automatically close if the compressor continues to run after cut-off pressure is reached. The check valve functions to prevent dangerous over-pressurization of the tank that could lead to equipment failure, serious injury, death, or property damage.
  • Air Filter / Moisture Separator – Because this compressor is optimized for use with plasma cutting equipment, an in-line air filter / moisture separator is present on the front of the unit. Plasma cutters require clean, dry air that is oil free.
  • Tank Pressure Gauge – This gauge displays the pressure [PSI] inside of the air tank.
  • Output Pressure Regulator – The output regulator allows the user to adjust the pressure of the air flowing out of the tank. This pressure can be less than or equal to the tank pressure.
  • Telescoping Luggage Handle (4.5CFM Unit Only) – The 4.5CFM air compressor model includes a telescoping luggage handle for easy transportation. This handle can be used in the extended or collapsed positions.
  • Output Pressure Gauge – This gauge displays the pressure [PSI] of the air flowing out of the air tank.
  • Air Output Quick Connect Ports – This compressor is equipped with two ¼” quick connect air hose ports.
  • Compressor – This is the electrically driven mechanical component that pressurizes the air tank.
  • 4-Gallon Air Tank – This compressor is equipped with a 4-gallon air tank that was designed and may be UM coded according to ASME Section VIII, Div. 1 rules. All pressure vessels including compressed air tanks should be inspected once every two years. To find your state pressure vessels inspector, search for the Division of Labor and Industries on the internet or in the government section of your local phone book.
  • Plasma Cutter Rack (4.5CFM Unit Only) – The 4.5CFM air compressor is equipped with a plasma cutter rack. Mounting brackets for your Forney Plasma Cutter are sold separately. To determine which mounting brackets you need based on your plasma cutter model, please visit www.forneyind.com.
  • Compressor Cart Interface Pegs – This air compressor was specifically designed to be mounted on a cart for customer convenience. The Compressor Cart Interface Pegs (M) and the Rubber Feet (O) are interchangeable based on the configuration that matches your needs. For normal use, the Rubber Feet should be installed. For use with the Forney Compressor Cart, remove the Rubber Feet and replace them with the Cart Interface Pegs (SEE IMAGES ON NEXT PAGE). For more information on the Forney Compressor Cart, please visit www.forneyind.com.
  • Power Cable Wrap – This air compressor has a built-in cable wrap located beneath the control panel for your convenience.
  • Rubber Feet – 4 rubber feet are supplied with your air compressor. These should be installed on the bottom of the compressor and act to prevent the frame of the compressor from contacting the ground. These also act as vibration dampers during compressor operation.

  • Air Tank Drain Valve – The air tank drain valve allows you to drain the air tank after each use. This valve is located on the bottom of the air tank. During normal use and operation of your air compressor, water will condense in the air tank. If this water is not drained from the tank after each use, rust may build up inside of the tank weakening its structural integrity. Turning the head of the valve counterclockwise will open the tank valve, and turning it clockwise will close the tank valve.
  • Front Carry Handle (2.5CFM Unit Only) – Because the 2.5CFM air compressor is relatively light, it can be safely lifted if proper lifting techniques are used. For this reason, the air compressor has a front and rear carry handle for your convenience.
  • Rear Carry Handle (2.5CFM Unit Only) – Because the 2.5CFM air compressor is relatively light, it can be safely if proper lifting techniques are used. For this reason, the air compressor has a front and rear carry handle for your convenience.
  • Wheels (4.5CFM Unit Only) – Because the 4.5CFM air compressor is too heavy to lift by yourself, dolly wheels are included for your convenience. The air compressor can easily be moved from location to location when using the dolly wheels in conjunction with the telescoping luggage handle (G).

Operation

The following procedure explains in detail how to operate your air compressor. These instructions are identical for both the 2.5CFM and 4.5CFM compressor units.

  1. Choose a suitable location for your air compressor. The air compressor should be placed on a flat surface at ground level away from any and all flammable materials, liquids, vapors, or gases. If compressed air is needed above ground level (i.e. on a roof), use longer air hoses. DO NOT use your air compressor in a damp environment or outside while it is raining. The air compressor should have at least 12 inches of open space on all sides to allow for adequate cooling air flow. If spraying flammable materials, locate the compressor at least 25 feet away from the spray area.

  2. Plug in your air compressor. Your compressor should be plugged into a standard 110-120 Volt wall outlet on an independent 15-20 Amp circuit leg that is properly grounded. DO NOT remove the ground pin from the electrical plug on the compressor.

    • If using an extension cord:
    • The extension cord must have a 3-blade grounding plug and a 3-slot receptacle that will accept the air compressor plug.
    • The extension cord should be no longer than 25 feet. Using an extension cord that is longer than 25 feet will cause a voltage drop at the compressor and will limit compressor performance.
    • The extension cord should be at least 12 gauge (AWG) or larger. Note, wire sizes increase as the gauge number decreases. DO NOT USE 14, 16, or 18 AWG EXTENSION CORDS.
  3. Use appropriate safety equipment. ALWAYS use the following safety equipment when operating your air compressor:

    • Respirator that is in accordance with ANSI Z88.2.
    • Hearing protection that is in accordance with ANSI S12.6 (S3.19).
    • Eye protection that is in accordance with ANSI Z87.1.
  4. Ensure that the air tank drain valve is closed. Locate the air tank drain valve on the bottom of the air tank. Ensure that it is fully closed by turning it clockwise until it comes to a stop.

  5. Turn on your air compressor. Locate the On/Off switch and rotate the switch lever from “Off” to “Auto”. The compressor should kick on and the tank should start filling with compressed air. Once the tank pressure reaches 125 PSI, the compressor should turn off automatically. The compressor will automatically refill the tank when the tank pressure reaches approximately 90 PSI.

  6. Connect air hoses. Your compressor is equipped with quarter inch (1/4”) universal quick connect air couplers. To attach the air hose, slide back the collar on the quick connect port, insert the male end of the air hose into the quick connect port, and release the collar.

  7. Adjust the output pressure. Before making any adjustments, ensure the tank is fully pressurized and
    the compressor has stopped. Turning the knob clockwise will increase the output pressure and turning it counterclockwise will decrease the output pressure.

  8. Turn off the air compressor. When finished using the air compressor, turn it off by rotating the On/Off switch lever from the “Auto” position to the “Off” position.

  9. Drain the air tank. The air tank must be drained after each use. Locate the air tank drain valve and open it slowly by turning the valve head counterclockwise. Once air starts hissing out of the tank, continue to rotate the valve head counterclockwise by approximately half of a turn. It is normal for water to spray out of the tank during this process. Once completed, close the air tank valve.

  10. Storage. Store the air compressor in a clean, dry, non-freezing environment at ground level. DO NOT store the compressor on a table, workbench, shelf, etc. to avoid injury or property damage.

Motor Overload Protection

Your new air compressor is equipped with automatic thermal overload protection. If the compressor motor overheats for any reason, it will automatically shut down.
If your air compressor enters thermal protection mode, the motor must be allowed to cool for at least one hour. DO NOT attempt to use the air compressor during this cooling period.

Disconnecting Air Hoses

When finished using your air compressor, disconnect air hoses from the control manifold using the following steps:

  1. Ensure that the air tank is completely empty. The air tank pressure gauge must read 0 PSI.
  2. Slide back the quick connect collar on the air compressor to release the air hose.

Compressor Break-In Procedure

Before the first use of your air compressor (or if any major compressor components have been recently replaced), please follow the following break-in procedure to ensure optimum performance:

  1. After verifying the air compressor is unplugged and powered off, open the air tank drain valve by rotating the valve head counterclockwise.
  2. Plug the air compressor into an appropriate 110-120V wall outlet.
  3. Rotate the On/Off switch lever from the “Off” position to the “Auto” position. The compressor will start up automatically.
  4. Allow the air compressor to run continuously for 20 minutes.
  5. Rotate the On/Off switch lever from the “Auto” position to the “Off” position.
  6. Unplug the air compressor.
  7. Close the air tank drain valve by rotating the valve head clockwise until it comes to a stop.
