3. Setup
The ETENWOLF G100 tire pressure gauge is ready to use out of the box. No assembly or batteries are required.
- Remove the gauge from its protective storage case.
- Ensure the tire valve stem is clean and free from dirt or debris.
- Remove the existing valve cap from the tire.
4. Operating Instructions
4.1 Checking Tire Pressure
- With the tire cold (driven less than a mile), firmly press the chuck of the gauge onto the tire valve stem. You should hear a brief hiss of air as the gauge connects.
- Maintain a firm, straight push to ensure a good seal and prevent air leakage.
- The pressure reading will be displayed on the gauge's scale. The inner bar will extend to indicate the pressure.
- Remove the gauge from the valve stem to lock the reading.
- Read the pressure indicated by the edge of the inner bar.
- Compare this reading to the recommended tire pressure for your vehicle (usually found on a sticker inside the driver's side door jamb, glove compartment, or owner's manual).

4.2 Deflating Function
If your tire pressure is too high, the ETENWOLF G100 gauge can be used to release air:
- After taking a pressure reading, if the pressure is above the recommended level, gently press the small button or pin on the side of the gauge (if present, or slightly depress the chuck) while it is still on the valve stem.
- Air will be released from the tire.
- Re-check the pressure periodically until the desired PSI is reached.

4.3 Replacing Tire Caps
After checking or adjusting tire pressure, always replace the valve cap to prevent dirt and moisture from entering the valve stem.
- Screw one of the provided universal tire caps onto the valve stem until snug. Do not overtighten.
5. Maintenance
- Keep the gauge clean and free from dirt, grease, and moisture. Wipe with a soft, dry cloth after each use.
- Store the gauge in its protective case when not in use to prevent damage and maintain accuracy.
- Avoid dropping the gauge or subjecting it to harsh impacts, as this can affect its calibration.
- Do not attempt to disassemble the gauge. Internal components are factory calibrated and not user-serviceable.
6. Troubleshooting
6.1 Inaccurate Readings
- Issue: Gauge consistently shows incorrect pressure.
- Solution:
- Ensure the gauge is pressed firmly and squarely onto the valve stem to prevent air leakage during measurement.
- Verify that the tire is cold before taking a reading.
- Compare the reading with another known accurate gauge. If discrepancies persist, the gauge may require professional calibration or replacement.
6.2 Air Leakage During Measurement
- Issue: Air hisses continuously when attaching the gauge.
- Solution:
- Press the gauge chuck more firmly and directly onto the valve stem.
- Check the valve stem for damage or debris that might prevent a proper seal.
- The ETENWOLF G100 features a deeper socket to minimize leakage, but a poor connection can still occur.

8. User Tips
- Check Regularly: It is recommended to check your tire pressure at least once a week, especially before long trips, to ensure safety and optimal fuel efficiency.
- Cold Tires: Always measure tire pressure when tires are cold. Driving heats up tires and increases pressure, leading to inaccurate readings.
- Proper Sealing: A quick, firm push onto the valve stem is key to getting an accurate reading without significant air loss.
- Valve Caps: Always replace valve caps after checking pressure to protect the valve stem from dirt and moisture.
- Multiple Vehicles: The ETENWOLF G100 is versatile and can be used for various vehicles including cars, trucks, SUVs, motorcycles, and bicycles.
