Setup
The ATsafepro Pencil Tire Pressure Gauge requires no assembly or batteries. It is ready for immediate use upon removal from its packaging.
- Ensure the tire valve stem is clean and free from dirt or debris.
- Remove the valve cap from the tire valve.
Operating Instructions
Follow these steps to accurately measure your tire pressure:
- Prepare the Tire: Ensure the tire is cold (driven less than a mile) for the most accurate reading.
- Remove Valve Cap: Unscrew the valve cap from the tire's valve stem.
- Attach Gauge: Firmly press the chuck (nozzle) of the tire pressure gauge straight onto the tire valve stem. You should hear a brief hiss of air as the gauge makes a seal. Maintain a tight seal to prevent air leakage.
- Read Pressure: The scale bar will slide out from the gauge body, indicating the tire pressure. Read the measurement directly from the scale bar.
- Remove Gauge: Once the reading is taken, remove the gauge from the valve stem. The scale bar will remain extended, holding the reading until manually reset.
- Reset Gauge: Push the extended scale bar back into the gauge body to reset it for the next measurement.
- Replace Valve Cap: Screw the valve cap back onto the tire valve stem to protect it from dirt and moisture.

Important Note: Do not exceed the maximum pressure rating of the gauge (50 PSI or 75 PSI, depending on the model). Exceeding this limit can permanently damage the device and compromise its accuracy.
Maintenance
To ensure the longevity and accuracy of your ATsafepro Pencil Tire Pressure Gauge, follow these maintenance guidelines:
- Cleaning: Wipe the gauge with a soft, dry cloth after each use to remove dirt, dust, or moisture. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the gauge in a clean, dry place, away from extreme temperatures and direct sunlight. The integrated pocket clip allows for convenient storage in a tool belt, workbench, or pocket.
- Inspection: Periodically inspect the nozzle and body for any signs of damage or wear. Ensure the scale bar moves smoothly.
- Avoid Drops: While durable, dropping the gauge on hard surfaces can affect its calibration and accuracy. Handle with care.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Reading | Gauge not fully seated on valve; tire not cold; gauge damaged. | Ensure a tight seal on the valve. Measure when tires are cold. If consistently inaccurate, the gauge may need replacement. |
| Air Leakage During Measurement | Gauge not pressed firmly enough; valve stem bent or damaged. | Press the gauge more firmly and straight onto the valve. Inspect the valve stem for damage. |
| Scale Bar Does Not Extend | No pressure in tire; gauge mechanism stuck. | Check if the tire is completely flat. Gently tap the gauge to free the mechanism. If still stuck, the gauge may be faulty. |
