4. Setup
- Initial Charge: Before first use, fully charge the inflator using the provided USB-C cable. Connect the cable to the USB-C port on top of the device and plug the other end into a compatible USB power source (e.g., computer, wall adapter). The display will indicate charging status.
- Connect to Air Source: Attach the inflator's male quick-connect fitting to your compressed air system's female quick-connect coupler. Ensure a secure connection.
- Prepare for Use: The inflator is now ready to be connected to a tire valve.
5. Operating Instructions
- Power On/Off: Press the "ON/UNIT" button located below the display to power on the device. The display will illuminate and show the current pressure unit. To power off, press and hold the "ON/UNIT" button for a few seconds, or the device will automatically shut off after a period of inactivity to conserve battery.
- Select Pressure Unit: While the device is on, short press the "ON/UNIT" button to cycle through available pressure units (e.g., PSI, BAR, KPA).
- Attach to Tire Valve: Firmly press the locking brass tire chuck onto the tire's valve stem until it locks securely. You may hear a slight hiss as air fills the hose.
- Read Pressure: Once attached, the digital display will show the current tire pressure. The 3-position lever throttle should be in the neutral (middle) position for reading.
- Inflate Tire: To inflate, push the 3-position lever throttle forward (towards the hose). Air will flow into the tire, and the display will show the increasing pressure. Release the lever to stop inflation.
- Deflate Tire: To deflate, pull the 3-position lever throttle backward (towards the handle). Air will be released from the tire, and the display will show the decreasing pressure. Release the lever to stop deflation.
- Remove from Valve: Once the desired pressure is reached, pull the locking brass tire chuck off the valve stem.
6. Maintenance
- Cleaning: Wipe the device with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no moisture enters the USB-C port or display.
- Storage: Store the inflator in a cool, dry place. Avoid extreme temperatures and direct sunlight.
- Battery Care: Recharge the battery regularly, even if not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Hose and Chuck Inspection: Periodically inspect the stainless-steel hose and brass chuck for any signs of wear, cracks, or damage. Replace if necessary.
