4.2 Connecting to an Air Compressor

1. Ensure your air compressor is off and its air tank is depressurized.
2. Connect the 1/4" NPT Quick-connect male fitting of the inflator to the female coupler of your air compressor hose.
3. Verify the connection is secure to prevent air leaks.

5. Operation

5.1 Powering On and Unit Selection

• Press the ON/OFF button to turn on the digital gauge. The display will illuminate.
• Press the FUNC button repeatedly to cycle through the available pressure units: PSI, BAR, KPA, and KG/CM². Select your desired unit. The device features smart unit memory, retaining your last selection.

5.2 Measuring Tire Pressure

1. Ensure the inflator is connected to an air compressor (even if not inflating, for proper gauge function).
2. Press the ON/OFF button to activate the gauge.
3. Firmly press the air chuck onto the tire valve stem. The clip design allows for hands-free attachment.
4. The current tire pressure will be displayed on the LCD screen.

5.3 Inflating Tires

1. Connect the air chuck to the tire valve stem as described in Section 5.2.
2. Ensure the air compressor is turned on and supplying air.
3. Squeeze the trigger handle of the inflator to begin inflating the tire. The digital display will show the increasing pressure.
4. Release the trigger once the desired pressure is reached.
5. Remove the air chuck from the tire valve.

5.4 Deflating Tires (Bleed Function)

If the tire pressure is too high, use the built-in bleed button:

• With the air chuck connected to the tire valve and the gauge displaying pressure, press the bleed button (often located near the gauge or handle).
• Air will be released from the tire, and the digital display will show the decreasing pressure.
• Release the bleed button when the desired pressure is achieved.

6. Maintenance

• Cleaning: Wipe the inflator with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the device in a dry, dust-free environment. Avoid direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries when the display becomes dim or the device fails to power on. Refer to Section 4.1 for battery installation.
• Hose and Fittings: Regularly check the rubber hose and quick-connect fittings for wear, cracks, or damage. Replace if necessary to ensure proper sealing and safety.
