3. Setup
The GODESON Dual Head Tire Pressure Gauge requires no assembly or batteries. It is ready for immediate use upon removal from its packaging.
- Inspect the gauge for any visible damage before first use.
- Ensure the gauge is clean and free of debris that could affect its accuracy.
4. Operating Instructions
Follow these steps to accurately measure your tire pressure:
- Remove Valve Cap: Unscrew the valve cap from the tire's valve stem.
- Select Chuck: Choose the appropriate chuck end for your tire valve. Use the straight foot air chuck for outer wheels or the 30-degree reverse chuck for inner wheels or hard-to-reach valves.
- Apply Gauge: Firmly push the selected chuck onto the tire valve stem. You will hear a brief hiss of air as the gauge connects. Maintain a tight seal to prevent air leakage.
- Read Pressure: The internal scale bar will slide out, indicating the tire pressure. Read the measurement directly from the scale. The gauge displays pressure in both PSI and Bar.
- Remove Gauge: Pull the gauge straight off the valve stem. The reading will remain displayed until the scale bar is manually pushed back in.
- Replace Valve Cap: Screw the valve cap back onto the tire valve stem to prevent dirt and moisture from entering.
It is recommended to check tire pressure when tires are cold for the most accurate reading.

5. Maintenance
Proper maintenance ensures the longevity and accuracy of your tire pressure gauge.
- Cleaning: Wipe the gauge with a soft, dry cloth after each use to remove dirt and grime. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the gauge in a clean, dry place, away from extreme temperatures and direct sunlight. The integrated hanging ring can be used for convenient storage.
- Inspection: Periodically check the gauge for any signs of wear or damage, especially to the chucks and the scale bar.
6. Troubleshooting
If you encounter issues with your tire pressure gauge, consider the following:
- Inaccurate Reading: Ensure the chuck is firmly seated on the valve stem without any air leaks during measurement. Check if the tire valve itself is damaged or leaking.
- Gauge Not Registering: Verify that the gauge is pushed far enough onto the valve stem to engage the internal pin.
- Stuck Scale Bar: Ensure the gauge is clean and free of debris. If the scale bar is stiff, gently try to push it back in. Avoid forcing it.
If problems persist, contact customer support for further assistance.
