Operating Instructions

1. Checking Tire Pressure:

1. Ensure the inflator is powered on and the correct pressure unit is selected.
2. Remove the valve cap from the tire.
3. Press the dual chuck firmly onto the tire valve stem. For Schrader valves, push straight on. For Presta valves, ensure the Presta side of the chuck is used. The gauge will display the current tire pressure.
4. Read the pressure displayed on the LCD screen.
5. Remove the chuck from the valve stem and replace the valve cap.

2. Inflating Tires:

1. Follow steps 1-3 from "Checking Tire Pressure" to attach the inflator to the tire valve.
2. Ensure your air compressor is turned on and supplying air.
3. Press and hold the trigger on the inflator handle to begin inflation. The digital gauge will show the pressure increasing in real-time.
4. Release the trigger once the desired pressure is reached.
5. Remove the chuck from the valve stem and replace the valve cap.

3. Deflating Tires:

1. Attach the inflator to the tire valve as described in "Checking Tire Pressure". The current pressure will be displayed.
2. Press the air bleeder valve (small button or lever near the chuck) to release air from the tire.
3. Monitor the digital display until the desired lower pressure is achieved.
4. Release the air bleeder valve, then remove the chuck and replace the valve cap.

4. Using Lock-On Feature (for Presta/Schrader):

The chuck features a lever to secure it onto the valve stem for hands-free operation during inflation.

1. Push the chuck onto the valve stem.
2. Push the lever down to lock the chuck onto the valve stem.
3. To unlock, pull the lever up.

Maintenance

• Cleaning: Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
• Storage: Store the inflator in a dry, cool place away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries when the low battery indicator appears on the LCD screen. Ensure proper battery disposal.
• Hose and Chuck Inspection: Regularly inspect the hose and chuck for any signs of wear, cracks, or damage. Replace if necessary to maintain air-tight seals.
