IMPORTANT SAFETY INFORMATION

General Safety Warnings

WARNING Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

  1. Work area safety
    1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
    2. Do not operate the Compressor in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Compressor motors produce sparks which may ignite the dust or fumes.
    3. Keep children and bystanders away from an operating compressor.
  2. Electrical safety
    1. Compressor plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded compressors. Standard plugs and matching outlets will reduce risk of electric shock.
    2. Do not expose compressor to rain or wet conditions. Water entering a compressor will increase the risk of electric shock.
    3. Do not abuse the cord. Never use the cord for unplugging the compressor. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
  3. Personal safety
    1. Stay alert, watch what you are doing and use common sense when operating this compressor. Do not use this compressor while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating a compressor may result in serious personal injury.
    2. Use personal protective equipment. Always wear ANSI-approved eye protection during setup and use.
    3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source or moving the compressor.
  4. Compressor use and care
    1. Do not use the compressor if the switch does not turn it on and off. Any compressor that cannot be controlled with the switch is dangerous and must be repaired.
    2. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the compressor. Such preventive safety measures reduce the risk of starting the compressor accidentally.
    3. Store an idle compressor out of the reach of children and do not allow persons unfamiliar with the compressor or these instructions to operate it. A compressor is dangerous in the hands of untrained users.
    4. Maintain the compressor. Keep the compressor clean for better and safer performance. Follow instructions for lubricating and changing accessories. Keep dry, clean and free from oil and grease. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the compressor’s operation. If damaged, have the compressor repaired before use. Many accidents are caused by a poorly maintained compressor.
    5. Use the compressor in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the compressor for operations different from those intended could result in a hazardous situation.
  5. Service
    1. Have your compressor serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the compressor is maintained.

Operating Instructions

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

Compressor Area Set Up

1. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent injury.
2. Locate the Compressor on a flat level surface. Route the air hose along a safe route to reach the work area without creating a tripping hazard or exposing the air hose to possible damage. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.

General Operation

  1. Turn the On/Off Switch to the “OFF” position.
  2. Connect the coiled Air Hose to the Compressor Hose.
    1. Pull back on the collar of the Air Hose’s coupler.
    2. Firmly insert the Compressor Hose connector into the coupler.
    3. Release the collar, which will snap the connector into place.
    4. Pull lightly on both hoses to ensure a proper connection.
  3. Select the desired Nozzle accessory and attach it to the end of the Air Nozzle.
  4. Turn on the car engine.
  5. Attach the clamps on the Power Cord onto the 12V automotive battery (not included) power source.
    1. Connect the RED clamp of the Compressor to the positive (+) terminal of the battery.
    2. Connect the BLACK terminal of the Compressor to a good ground source on the engine block.
      WARNING! Do NOT connect it to the other battery terminal.
      Note: Connect to 12VDC power source only.
  6. Be sure the valve stem is clean and free of dirt.
  7. Turn the Compressor On/Off Switch to the “ON” position.
    Note: Turn the Compressor on before connecting to the tire valve to prevent blowing the fuse.
  8. Holding the Air Nozzle Grip, connect the Nozzle to the valve stem of the item to be inflated.
  9. Monitor the Pressure Gauge carefully to avoid over-inflating the item.
  10. Continue inflating until the recommended pressure is reached.
  11. Turn the compressor On/Off Switch to the “OFF” position.
  12. Remove the Nozzle from the object.
  13. Verify tire pressure with a tire pressure gauge (not included), then replace the valve cap where applicable.
  14. If the tire pressure is low, repeat the steps beginning with Step 7.
  15. When finished, remove the Clamps from the power source.
    CAUTION! The metal parts of the compressor and hoses will become hot during use. Do not touch them.
  16. Allow the Compressor to cool, then wipe down and replace into the included storage bag. Return the Nozzles to the small storage bag attached to the Compressor Hose.
  17. Store in a dry location.

Maintenance and Servicing

Procedures not specifically explained in this manual must be performed only by a qualified technician. TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Turn the Power Switch “OFF” and disconnect the Battery Clamps before performing any inspection, maintenance, or cleaning procedures. TO PREVENT SERIOUS INJURY FROM COMPRESSOR FAILURE: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.

Cleaning, Maintenance, and Lubrication

  1. BEFORE EACH USE, inspect the general condition of the air compressor. Check for:
    • loose hardware,
    • misalignment or binding of parts,
    • cracked or broken parts,
    • damaged electrical wiring, and
    • any other condition that may affect its safe operation.
