2. Connect Air Hose: The compressor features both high-pressure and low-pressure inflation/deflation ports. For high-pressure tasks like tires, connect the appropriate chuck to the high-pressure outlet. For low-pressure tasks like inflatables, attach the large diameter hose to the low-pressure port.

3. Power On: Press the power button on the control panel to turn on the compressor. The digital display will illuminate.

Operating Instructions

General Operation

The control panel features a digital display, mode selection, and +/- buttons for adjusting pressure settings. The compressor has an automatic shut-off feature once the set pressure is reached.

High-Pressure Inflation (Tires)

1. Set Desired Pressure: Use the +/- buttons on the control panel to set the target PSI (Pounds per Square Inch) for your tire. Refer to your vehicle's owner's manual or tire sidewall for recommended pressure.
2. Connect Chuck: Securely attach the high-pressure chuck to the tire valve stem. Ensure a tight seal to prevent air leakage.
3. Start Inflation: Press the START/STOP button to begin inflation. The compressor will automatically stop once the preset PSI is reached.
4. Disconnect: Once inflation is complete, disconnect the chuck from the valve stem.

Low-Pressure Inflation/Deflation (Inflatables)

1. Attach Large Hose: Connect the large diameter hose to the low-pressure inflation/deflation port. Select the appropriate nozzle for your inflatable item.
2. Inflate/Deflate: For inflation, connect the hose to the item and press the START/STOP button. For deflation, connect the hose to the item and select the deflation mode (if available, or reverse the hose connection if applicable to the specific model).
3. Monitor: Monitor the inflation/deflation process visually. This mode does not have an automatic shut-off based on pressure.

Maintenance

• Drain Air Tank: Regularly drain moisture from the air tank using the 1/4 turn tank drain valve located at the bottom of the tank. This prevents rust and extends the life of the compressor.
• Clean Air Filter: Periodically inspect and clean the air filter to ensure optimal performance. Refer to the manual for specific cleaning instructions.
• Store Properly: Store the compressor in a clean, dry area away from extreme temperatures. Disconnect the battery when not in use for extended periods.
