6. Operating Instructions

6.1 Inflating Tires

Connect Air Hose: Unscrew the valve cap from the tire. Securely screw the inflator's air hose connector onto the tire valve stem. For optimal connection, ensure it is threaded tightly.
Check Current Pressure: Once connected, the digital display will show the current pressure of the tire.
Select Mode (Optional): Press the 'M' button to cycle through different inflation modes (e.g., car, motorcycle, bicycle, ball, custom). Each mode has a default preset pressure, but you can adjust it.
Set Target Pressure: Use the '+' and '-' buttons to set your desired target pressure (PSI, BAR, KPA, or kg/cm²). Refer to your vehicle's door jamb sticker or owner's manual for recommended tire pressure.
Start Inflation: Press the Play/Pause button (►►) to begin inflation. The inflator will automatically stop once the preset target pressure is reached.
Disconnect: After inflation, wait approximately 2 minutes for the hose to cool down before unscrewing it from the tire valve to avoid burns. Replace the valve cap.

Cleaning: Wipe the inflator with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
Storage: Store the inflator in its provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the power cord and air hose are properly coiled and secured in their designated storage slots on the unit's back.
Fuse Replacement: If the inflator does not power on, check the fuse located in the 12V DC power plug. Replace it with the spare fuse provided if necessary.

8. Troubleshooting

Problem	Possible Cause	Solution
Inflator does not turn on.	No power from 12V DC socket; Blown fuse in plug.	Ensure vehicle engine is running and socket is functional. Check and replace fuse in the 12V DC plug.
Inflator stops before reaching target pressure.	Target pressure set too low; Overheating protection activated.	Verify target pressure setting. Allow unit to cool down for 15-20 minutes before resuming operation.
Pressure reading is inaccurate.	Loose connection to tire valve; Sensor calibration.	Ensure the air hose is securely threaded onto the tire valve. Use a separate, calibrated tire gauge to verify pressure if accuracy is critical.
Slow inflation.	Low vehicle battery voltage; Air leak in connection.	Ensure vehicle engine is running. Check for air leaks at the connection point and tighten if necessary.
