OPERATION INSTRUCTIONS

CHECKING TIRE PRESSURE

1. Connect the inflater gauge to an air compres­sor using the quick-connect air fitting.

2. Turn the inflater gauge on by pressing the Power I Unit button. Press it again to select the unit you would like to measure in. Press the Air Bleed Valve / Reset button to ensure the gauge is set to zero.

3. Use the chuck to connect to the tyre valve by pressing the tyre’s valve stem into the mouth of the chuck. The twist-on chuck will screw into the threads of the tyre’s valve stem. For the locking chuck, press the trigger while placing it onto the valve stem and release it once there is a strong seal. It should lock into place.

4. Fill by pressing the valve trigger until the desired pressure is reached.
   NOTE: While filling the tire, the pressure reading will not indicate the exact pressure of the tyre. To check on the tire’s current pressure, release the valve trigger and the display will instantaneously show the tire’s pressure.

5. Release excess air by using the Air Bleed Valve / Reset button. If the tyre’s pressure is higher than the desired level. press the Air Bleed Valve to decrease the pressure. NOTE: While bleeding air from the tyre, the pressure reading will not indicate the exact pressure of the tyre. To check on the tyre’s current pressure, release the Air Bleed Valve and the display will instanta­neously show the tire’s pressure.

6. The gauge will automatically shut off 20- 60 seconds after use. The gauge can be manually turned off by holding the Power/ Unit button down for more than three seconds.

CHECKING TIRE PRESSURE

• The inflator gauge can be used to check tire pressure without connecting to an air compressor.
• Use one of the interchangeable air chucks to connect the inflator to the tire’s valve stem. Press the air chuck tight to prevent air leakage.
• Press the Power/Unit button to turn on the tire inflator gauge, press it again to choose the desired unit.

NOTE: What to do if air leaks through the chuck?

• Connect the chuck to the tire valve and press hard to get a good seal.
• Rotate the chuck clockwise 180°-360° to stop the air from leaking,

CHANGING THE BATTERY

1. Locate the battery compartment on the back of the tire pressure gauge and remove the back cover.
2. Locate the 2 x AAA batteries, remove them, and replace them with new batteries. Ensure the batteries are placed in the correct direction, matching polarity with the indicated diagrams.

TROUBLESHOOTING

Trouble: Air Leaking Solution

• It is normal for air to leak slightly when the chuck is connected and removed from the tire valve.
• Check if there is a strong seal between the chuck and tire valve.
• Adjust the angle between the air chuck and tire valve.
• Check all the connection points of the air compressor, inflator, quick-connect fitting, air chuck, and tire valve stem. All connections should not leak; threads may require Teflon tape for a complete seal.
• Contact us for help.

Trouble: Inaccurate Reading Solution

• Adjust the angle between the air chuck and the tire valve to ensure a strong seal.
• Small reading differences between gauges are normal. For large discrepancies, please contact us for help.

Trouble: Slow Inflation

• Solution: It takes approximately 2 minutes to inflate a normal car tire from Oto 35 PSI. If it takes longer to do so, please contact us.
• Trouble: Backlit Will Not Turn on
• Solution: Press the Backlit button. If it does not work, replace the battery.
