Operating Instructions

The GERCHWAY Digital Tire Pressure Gauge offers three primary functions: inflating, checking pressure, and deflating.

1. Turn On: Press the power button to activate the digital display.
2. Select Unit: Press the "UNIT" button to cycle through available pressure units: PSI, BAR, KPA, and KG/CM². Select your preferred unit.
3. Attach to Tire Valve: Firmly press the swivel air chuck onto the tire's valve stem. The 360° swivel design allows for easy attachment from any angle. A secure connection will prevent air leakage and allow for accurate readings.
4. Check Pressure: Once attached, the current tire pressure will be displayed on the screen.
5. Inflate Tire: Squeeze the trigger handle to begin inflating the tire. The display will show the pressure increasing in real-time. Release the trigger when the desired pressure is reached.
6. Deflate Tire: If you over-inflate, press the built-in air bleeder valve (usually a small button or lever near the trigger) to release air until the desired pressure is achieved.
7. Remove Gauge: Once the desired pressure is set, carefully remove the air chuck from the tire valve.
8. Power Off: The device will automatically shut off after 60 seconds of inactivity to save battery. You can also manually turn it off by pressing and holding the power button.

Maintenance

• Cleaning: Wipe the gauge and hose with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
• Storage: Store the gauge in a clean, dry place away from extreme temperatures and direct sunlight.
• Battery Replacement: If the display becomes dim or the unit does not power on, replace the 2 AAA batteries. Ensure correct polarity.
• Check Connections: Periodically inspect the hose and air chuck for any signs of wear, cracks, or damage. Ensure all connections remain tight.
