Safety Instructions

  • Always operate the compressor in a well-ventilated area.
  • Ensure the vehicle engine is running before connecting the compressor to the battery to prevent battery drain.
  • Wear appropriate eye protection during operation.
  • Do not touch hot parts of the compressor during or immediately after use. The unit can become very hot.
  • Keep children and pets away from the compressor during operation.
  • Do not exceed the maximum PSI rating of the tire or the compressor.
  • The compressor features an auto-thermal cut-off switch and overheating protection. If the unit stops, allow it to cool down before resuming use.

Setup

  1. Prepare the Compressor: Place the compressor on a stable, flat surface near the tire to be inflated. Ensure the vehicle engine is running.
  2. Connect to Vehicle Battery: Connect the red clamp of the power cord to the positive (+) terminal of your vehicle's 12V battery and the black clamp to the negative (-) terminal.
  3. Connect Air Hose: Connect the quick-connect fitting of the 26ft rubber air hose to the compressor's air outlet.
  4. Attach to Tire Valve: Securely attach the thumb lock adapter of the air hose to the tire's valve stem. Ensure a tight seal to prevent air leakage.

Operating Instructions

  1. Turn On: Locate the power switch on the compressor and turn it to the 'ON' position. The compressor will begin to inflate the tire.
  2. Monitor Pressure: Observe the integrated pressure gauge on the air hose to monitor the tire pressure.
  3. Reach Desired PSI: Once the desired tire pressure is reached, turn the compressor off.
  4. Release Excess Air (if needed): If the tire is over-inflated, press the button on the back of the pressure gauge to release excess air until the correct PSI is achieved.
  5. Disconnect: Disconnect the thumb lock adapter from the tire valve stem and then disconnect the air hose from the compressor. Finally, disconnect the battery clamps from the vehicle battery.
