Operating Instructions

Jump Starting a Vehicle

1. Turn the vehicle ignition OFF.
2. Connect the POSITIVE (RED) clamp to the POSITIVE battery post.
3. Connect the NEGATIVE (BLACK) clamp to the vehicle chassis or engine block, away from the battery.
4. Turn the unit switch to ON.
5. Crank the engine for no more than 8 seconds. If it fails to start, wait 2 minutes before trying again.
6. Once started, turn the switch to OFF and disconnect the clamps.

Using the Air Compressor

1. Ensure battery clips are secured.
2. Remove the air compressor hose from the storage cleats.
3. Thread the adapter onto the valve stem.
4. Turn the compressor switch ON and inflate to the desired pressure.
5. Turn the switch OFF and remove the connector.

Maintenance and Storage

After use, wipe the battery clips, cords, and case with a dry cloth to remove corrosion, dirt, or oil. Ensure all components are in good working condition. Store in a cool, dry place. Avoid storing the unit where battery acid leakage could cause damage.

Troubleshooting

If the unit fails to jump-start, check for poor connections, reversed clamps, or a discharged internal battery. If the 12V device won't power on, check the device, the battery charge, or the internal 20A fuse. If the compressor shuts off, it may be overheated; allow it to cool before retrying.
