Introduction

Thank you for purchasing a California Air Tools, Inc. Air Compressor. This manual contains important instructions for operating this product. For your safety, and the safety of others, be sure to read this manual thoroughly before operating the product. Failure to properly follow all the instructions and precautions can cause you and others to be seriously hurt or killed.

Record the model and serial numbers indicated on your air compressor's nameplate:

This air compressor features a compact structure, stable performance, a high airflow rate, and easy operation and maintenance. Because the air compressor produces no oil in the airflow, it can be used as an independent air supply machine for situations in which oil in the airflow is an issue.

The motor directly drives the eccentric wheel-connecting bar system, making the piston move reciprocally. The piston is made from a high-temperature-resistant and abrasion-resistant nonmetallic material, and is able to function without lubrication for a long time.

Compressed air discharges in the air tank. A pressure gauge displays the pressure inside the tank. When the pressure inside the tank rises to 115-120 PSI, the power is automatically cut off by the pressure-control switch. When the pressure inside the tank lowers to 85-90 PSI, the power is turned back on by the pressure-control switch. This gradually raises the pressure in the air tank. This procedure happens repeatedly.

Package Contents & Assembly

Package Contents:

Assembly: Install the air filter

  1. Looking from the top down to the air compressor, attach the air filter to the back left side of the motor head. Screw the air filter into the threaded port, under the plastic heat shield located on the left motor head.
  2. Insert the 3 inch rubber tubing into the hole located on the cap of the air filter lid.

Inspect for Damage

Before using the air compressor, make sure the air tank is not damaged, inspect all parts for damage, and check that all pipes are firmly connected. Do not use the air compressor if any damage is found. If damaged, have an authorized service center inspect and test the air compressor to ensure that it is working properly.

Save Packaging

Save all outside packaging in case you ever need to return the product for service or repair.

Compressor Location

Use on Flat Surface

For proper operation, the air compressor must be placed on a flat surface with an incline no greater than 15 degrees.

Maintain a Clear Area

It is very important that the air compressor is positioned so that there is adequate airflow around the machine. There must be at least 2 feet of obstacle-free space surrounding and above the air compressor.

Use in Areas with Clean Air

For proper operation and to maximize the longevity of the air compressor, it is very important that the air drawn into the air compressor is clean. The air compressor should not be used in areas where dust or particulates are in the air. This will damage the motor and impair proper operation. IMPORTANT: Always use the air filter, properly installed.

Operating the Air Compressor

Electrical Power

Electrical Power Requirements

[DANGER] [⚡️ SHOCK] There is a danger of electric shock. Use only undamaged electrical cords. DO NOT touch bare wires or receptacles. DO NOT operate air compressor in wet weather or in wet conditions. DO NOT touch air compressor or cords if hands or feet are wet. Ensure that all cords are free of damage before connecting to the power supply. Ensure that you have a sufficient electrical supply for supporting the requirements of the motor.

Before using the air compressor, refer to the serial label for voltage and amperage requirements. Make sure you have a sufficient electrical supply for supporting the motor's requirements. Use a dedicated circuit for the best results. Low voltage and/or an overload circuit can cause the motor's overload protection system circuit breaker to trip.

Electrical Extension Cords

[CAUTION] Use caution when using extension cords. Use an extension cord which is no more than 25 feet long and at least 14 gauge. Using an excessively long or thin-wired extension cord will cause severe damage to the motor. Use only a 3-wire extension cord that has a 3-blade grounding plug. Inspect all electrical extension cords to ensure that they are free of damage. When using an extension cord, use a heavy-duty cord that is no more than 25 feet long and at least 14 gauge. Use only a 3-wire extension cord that has a 3-blade grounding plug.

Assembly

  1. Connect your air hose to the 1/4” quick connect coupling.
  2. Make sure the drainage valve is off and that the pressure switch is in the OFF position.
  3. Ensure that the power supply you are going to use is operating normally.
  4. Insert the power supply cord into the power supply socket.

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 115 - 120 PSI, the pressure switch will automatically turn the power off. This indicates the compressor is working normally.
  2. Turn the power switch to the Off position, unplug the power supply cord and release the air in the tank by pulling on the safety valve. At this point proceed to the next step (daily operations) starting the air compressor to continue to use.

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.

Daily Operation

Starting the compressor:

  1. Turn the power switch to the OFF position.
  2. Attach the air hose to the 1/4" quick connect coupler.
  3. Close the drainage valve.
  4. Turn the regulator knob completely to the left. This will turn down the pressure at the air hose before starting.
  5. Plug the power supply cord into a power supply socket.
  6. Turn the power switch to the ON position.
  7. Let the motor run and tank fill until motor turns off.
  8. Turn the regulator knob to the right increasing the pressure at the hose. Turn the pressure up until the desired pressure at the air hose is reached.
  9. Operate air tool normally.
  10. Only operate continuously for 1 hour maximum. Allow compressor to cool down before restarting.

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.

Maintenance

Draining the Air Tank

The frequency at which you should drain the air tank depends on the environmental conditions and the amount of operating time logged. The average draining frequency is every 2 to 3 days.

  1. Place the air compressor above a container capable of holding water.
  2. With compressed air in the air tank, slowly turn the drain valve knob to the right position to open the valve. The water in the air tank will drain out.
  3. After all of the accumulated water has drained out, turn the drain valve knob left or closed position in order to avoid leakage.

Changing the Air Filter

The air filter is designed to reduce noise and help prevent particulates in the air from entering and damaging the air compressor. After being used for a period of time, the air filter will become clogged. This will reduce the air intake capabilities of the air compressor, reducing performance. Therefore, the air filter must be replaced regularly.

  1. Open the lid on the air filter, then remove the old filter.
  2. Replace it with a new filter, then close the lid.

Testing for Leaks

Make sure all connections are tight. Do not overtighten. A small leak in any hose or pipe connection will reduce the air compressor's performance. To test for small leaks, spray a small amount of soapy water on the area suspected of leaking. If the soap bubbles, replace the broken part.

Cleaning

Clean items with a soft brush, or wipe with a moistened cloth using a biodegradable solvent. Do not use flammable liquids such as gasoline or alcohol. Always keep parts clean from dirt and dust for better performance.

Adjusting the Pressure Switch

The pressure switch is used to control the automatic stop-and-start function of the air compressor, ensuring the correct pressure of the compressed air in the air tank is maintained. If the pressure of the compressed air in the air tank is found not to be in the standard range set by the manufacturer, the pressure switch must be adjusted to correctly set the activation valve. (The pressure at which the air compressor will stop running is 8 bar, and the pressure at which the air compressor will start running again is 6 bar.)

Adjust the pressure switch as follows:

  1. Open the casing to access the pressure switch.
  2. Adjust the setting screw for the maximum pressure. Turning the setting screw clockwise makes the activation pressure higher, so the pressure at which the air compressor stops running will be higher.
  3. Adjust the setting screw for pressure difference. Turning the setting screw clockwise makes for a larger pressure difference, so the difference between the pressure at which the air compressor starts and the pressure at which the air compressor stops is larger.

Gradual adjustments should make the activation pressures within the range set by the manufacturer.

Storage

Before storing for a prolonged period of time:

  1. Turn off the power supply.
  2. Disconnect the power cord from the power supply.
  3. Pull the relief valve and release all the pressure from the air tank.
  4. Clean the air compressor to remove all dirt and dust.
  5. Cover the air compressor with a cover to protect the unit from dust and moisture.
  6. Do not stack or store any items on top of or around the air compressor. Damage could occur.

Troubleshooting

PROBLEMPOSSIBLE CAUSEPOSSIBLE SOLUTIONS
