6. Operating Instructions
6.1. Jump Starting a Vehicle
Ensure the jump starter is at least 50% charged before attempting to jump start a vehicle.
- Turn off the vehicle's ignition and all accessories.
- Connect the smart jumper cables to the jump start port on the KOPUO R66 unit. Ensure a secure connection.
- Connect the RED positive (+) clamp to the vehicle's positive (+) battery terminal.
- Connect the BLACK negative (-) clamp to the vehicle's negative (-) battery terminal or a solid, unpainted metal part of the engine block/chassis.
- Once connected, the smart cable indicator light will show its status (e.g., solid green for ready).
- Start the vehicle's engine. If it doesn't start immediately, wait 30 seconds and try again. Do not crank for more than 3 seconds per attempt.
- Once the vehicle starts, immediately disconnect the BLACK negative (-) clamp first, then the RED positive (+) clamp.
- Disconnect the smart jumper cables from the KOPUO R66 unit.
CAUTION: Do not touch the red and black clamps together once connected to the jump starter. Do not attempt to jump start a vehicle with a severely damaged or frozen battery.
6.2. Using the Air Compressor
The integrated air compressor can inflate tires and other inflatables up to 150 PSI.
- Connect the air hose to the air hose port on the KOPUO R66 unit.
- Attach the appropriate valve adapter to the air hose, if necessary, and then securely connect it to the item you wish to inflate (e.g., tire valve stem).
- Turn on the KOPUO R66 unit. The digital display will show the current pressure.
- Press the M (Mode) button to cycle through pressure units (PSI, BAR, KPA) or select a preset inflation mode (car, motorcycle, bicycle, ball).
- Use the + and - buttons to set your desired target pressure.
- Press the S (Start/Stop) button to begin inflation. The compressor will automatically stop once the preset pressure is reached.
- Disconnect the air hose from the item and the KOPUO R66 unit.
