5. Operating Instructions
5.1 Jump Starting a Vehicle
The LOKITHOR J1500 offers two jump-starting modes: Normal Start and Force Start.
Image: Visual guide showing the three steps for both Normal Start and Force Start procedures for the LOKITHOR J1500 jump starter.
Normal Start (Battery Voltage > 8V)
- Connect Clamps: Insert the LO-CLAMP-Pro jumper cable harness into the jump starter. Connect the red positive (+) clamp to the vehicle's positive (+) battery terminal and the black negative (-) clamp to the vehicle's negative (-) battery terminal.
- Wait for Green Light: The jump starter's display will show a flashing green light, indicating it is ready to start.
- Start Vehicle: Start your vehicle. Once the vehicle starts, immediately disconnect the clamps from the battery, then disconnect the jumper cable harness from the jump starter.
Force Start (Battery Voltage < 8V or completely dead)
Use this mode only if the Normal Start procedure fails. This mode bypasses some safety checks, so exercise caution.
- Connect Clamps: Insert the LO-CLAMP-Pro jumper cable harness into the jump starter. Connect the red positive (+) clamp to the vehicle's positive (+) battery terminal and the black negative (-) clamp to the vehicle's negative (-) battery terminal.
- Activate Force Start: Long press the Power Button and the LED Button simultaneously on the jump starter. The display will indicate Force Start mode.
- Start Vehicle: Start your vehicle. Once the vehicle starts, immediately disconnect the clamps from the battery, then disconnect the jumper cable harness from the jump starter.
