- 1.5-inch Glow-in-the-Dark Dial: Large, easy-to-read display with dual scales (PSI and Bar) that illuminates for visibility in low light.
- 360° Swiveling Brass Chuck: Allows for easy connection to tire valves from any angle, ensuring a secure seal and accurate reading.
- Pressure Hold Feature: The gauge holds the pressure reading until the release button is pressed, allowing for convenient viewing.
- Enlarged Release Button: Designed for comfortable and easy pressure release.
- Dual-Layer Rubber Protective Cover: Provides enhanced protection against impacts and offers a comfortable, non-slip grip.
- Robust Brass Construction: Ensures durability and long-term reliability.
Setup
The ATsafepro Mechanical Tyre Pressure Gauge requires no batteries or complex setup. It is ready for use right out of the box.
- Unpack the tyre pressure gauge from its packaging.
- Ensure the protective rubber cover is securely fitted around the gauge dial.
- Familiarize yourself with the chuck and the pressure release button.
Operating Instructions
Follow these steps to accurately measure your tire pressure:
- Prepare the Tire: Ensure the tire is cool. Remove the valve cap from the tire stem.
- Attach the Gauge: Firmly press the chuck of the ATsafepro gauge onto the tire valve stem. You may hear a slight hiss of air; this is normal. Ensure a tight seal to get an accurate reading. The 360° swiveling chuck allows for easy attachment from various angles.
- Read the Pressure: Once the gauge is securely attached, the needle on the dial will move to indicate the tire pressure. The gauge will hold this reading even after it is removed from the valve stem.
- Record the Reading: Note the pressure reading from the dial. The gauge displays pressure in both PSI (pounds per square inch) and Bar.
- Release Pressure (if needed): If the tire pressure is too high, press the enlarged release button on the side of the gauge to slowly release air until the desired pressure is reached. Re-check the pressure after releasing air.
- Remove and Replace: Remove the gauge from the valve stem and replace the valve cap securely.
- Reset Gauge: Press the release button to reset the gauge needle to zero before the next measurement.

Maintenance
To ensure the longevity and accuracy of your ATsafepro Tyre Pressure Gauge, follow these simple maintenance tips:
- Cleaning: Wipe the gauge with a soft, dry cloth after each use to remove dirt and grime. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the gauge in a clean, dry place, away from direct sunlight and extreme temperatures. The protective rubber cover helps guard against accidental damage.
- Avoid Drops: While designed with a shock guard, repeated drops can affect the gauge's calibration. Handle with care.
- Check for Damage: Periodically inspect the chuck and the gauge body for any signs of wear or damage. If the chuck appears worn or leaks air, it may affect accuracy.
Troubleshooting
If you encounter issues with your ATsafepro Tyre Pressure Gauge, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Reading | Improper seal with valve stem; gauge is dirty; gauge has been dropped/damaged. | Ensure chuck is firmly pressed onto valve stem; clean the gauge; if damaged, consider replacement. |
| Air Hissing During Measurement | Chuck not fully seated on valve stem; worn valve stem or chuck seal. | Press the chuck more firmly; inspect valve stem for damage; if issue persists, the chuck may be worn. |
| Needle Does Not Return to Zero | Pressure release button not fully pressed; internal mechanism issue. | Ensure the release button is fully depressed; if it remains stuck, contact customer support. |
