- Set Target Pressure: Use the '+' and '-' buttons to set your desired target pressure. The display will show the set value.
- Connect to Item: Remove the valve cap from the item you wish to inflate. Securely attach the air hose nozzle to the valve stem. For different items (bicycles, balls), use the appropriate nozzle adaptor.
- Start Inflation: Press the inflation button (▶) to begin inflation. The compressor will automatically stop once the preset pressure is reached.
- Monitor Pressure: The digital display will show the current pressure during inflation.
- Disconnect: Once inflation is complete, quickly disconnect the nozzle from the valve stem and replace the valve cap.
- Power Off: Press the power button (⏻) to turn off the inflator.

Inflation for Specific Items:
- Car Tyres:
Connect the air hose directly to the car tyre valve. Set the pressure according to your vehicle's manufacturer recommendations (usually found on a sticker inside the driver's door jamb or in the owner's manual). Inflation time for a standard 195 tyre from 0 to 36 PSI is approximately 5-6 minutes.

- Motorcycle Tyres:
Use the standard nozzle or a suitable adaptor if required. Refer to your motorcycle's manual for recommended tyre pressures.
- Bicycle Tyres:
Select the appropriate nozzle adaptor for your bicycle valve type (Presta or Schrader). Inflate to the pressure indicated on the tyre sidewall.
- Balls and Other Inflatables:
Attach the needle adaptor for sports balls or the cone adaptor for other inflatables (e.g., swimming rings). Inflate until firm, avoiding over-inflation.

Maintenance
- Cleaning: Wipe the exterior of the inflator with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
