Jump-Starting Procedure

Follow these steps carefully.

1. Ensure jump starter is fully charged and turned OFF.
2. Turn OFF the vehicle's ignition and all accessories (radio, lights).
3. Connect RED positive clamp (+) to the positive terminal of the dead battery.
4. Connect BLACK negative clamp (-) to a clean, unpainted metal part of the engine block or vehicle chassis, away from the battery and fuel lines.
5. Turn ON the jump starter unit (press POWER button).
6. Enter the vehicle and attempt to start the engine. Crank for no more than 5 seconds.
7. If engine does not start, wait 3 minutes before attempting again.
8. Once engine starts, turn OFF the jump starter unit.
9. Disconnect clamps in REVERSE order: Remove BLACK negative clamp first, then RED positive clamp.
10. Recharge the jump starter as soon as possible after use.

Tip: If engine fails to start after 3 attempts, the battery may be beyond recovery or there may be another mechanical issue.

Using the Air Compressor

For inflating tires, air mattresses, sports balls, etc.

1. Ensure the unit is turned ON and has sufficient charge.
2. Screw the compressor hose nozzle securely onto the item's valve stem.
3. Press the Compressor Power button to start inflation.
4. Monitor the pressure using your own gauge (unit does not have a built-in pressure gauge).
5. Press the Compressor button again to stop.
6. Unscrew the nozzle and replace valve cap.

WARNING! Do not run the compressor continuously for more than 10 minutes. Allow to cool for 20 minutes between uses. Do not use to inflate persons in rafts or life jackets.
