Warnings
- Read instructions first.
- This digital inflator is only intended for measuring, inflation, and deflation of vehicle tires with air. Any other use of this product is considered improper.
- Use only compressed, filtered, oil-free air.
- Do not exceed the inflators maximum pressure rating.
- Do not drop the device. It may influence the functionality and the calibrated accuracy.
- Warranty not applicable for devices that have been used improperly, taken apart, modified or with missing or broken parts or with traces of internal clogging caused by anti-puncture products, anti-corrosive fluids or ballast water. Must only be repaired by authorized personnel. Do not break the seals to maintain warranty and calibration.
- Best practice is short fill intervals followed by pressure reading.
- The pressure value may fluctuate for a few seconds after inflation/deflation and will then stabilize due to a natural thermodynamic phenomenon.
- Do not lock the trigger in inflation position unattended—risk of explosion!
- Do not inflate tires filled with water for ballast, anti-puncture products or anti-corrosive agents.
- Keep safe distance from tires during inflation. Stand outside the trajectory of any potential explosion.
- Adjust the tire pressure according to the tire and vehicle manufacturer’s recommendations
- Weather, temperature, altitude, and heat friction (from driving) affects the tire pressure. A rule of thumb is that an increase of 10 °C in ambient temperature will increase the tire pressure by 1.5 psi. For maximum accuracy carry out the inflation in the temperature range from 15° to 25 °C.
- The device recalibrates automatically to zero when connected to atmospheric pressure at the shutdown to improve accuracy. Carry out an initial inflation sequence and let the device shutdown if the device has changed environment (location/temperature) or not has been used for a long period. When calibrating the device must not be connected to a pressure source (e.g., tire). If so “Er.C” is written in display upon shutdown.
- Do not direct air at yourself or bystanders. Wear safety glasses and hearing protection (users and bystanders). Do not inflate when not connected to a tire. The hose can be tossed uncontrollably around.
- This product contains a button battery when put into use. If swallowed, a lithium button battery can cause severe or fatal injuries within two hours. Keep batteries out of reach of children. If you think batteries may have been swallowed or placed inside any part of the body, seek immediate medical attention.

To Calibrate
If the device has changed environment (location/temperature) or not has been used for a long period, carry out an inflation sequence and let the device shutdown to calibrate. The device recalibrates automatically to zero (at atmospheric pressure) at the shutdown to improve accuracy. When calibrating, the device must not be connected to a pressure source (e.g., tire).
Troubleshooting P.HI/P.LO
If maximum pressure was exceeded, P.HI will appear on the screen. Disconnect the unit from the tire (image 1).
If the pressure falls below minimum pressure, P.LO will appear on the screen. Disconnect the unit from the tire (image 1A).
To clear P.HI or P.LO error messages, remove and reinsert the battery (images 2 and 3).
Calibration Error
If unit is turned off while connected to a pressure source (tire), Er.C will appear on the screen. Carry out an inflation sequence and let the device shutdown clear the Er.C error message.
