6. Operating Instructions
6.1. Jump Starting a Vehicle
The LOKITHOR JC400 can jump start 12V vehicles with up to 8.5L gas or 6.5L diesel engines. It features a robust 2500A peak current and automatically detects voltage.
Image: Step-by-step guide for jump starting a vehicle with the LOKITHOR JC400, showing clamp attachment, device activation, mode selection, vehicle start, and power off.
- Attach Jumper Clamps: Connect the red positive (+) clamp to the positive battery terminal and the black negative (-) clamp to the negative battery terminal. Ensure a secure connection.
- Turn On Device: Press the Power Button on the JC400 to turn it on.
- Select Mode: Short press the Mode Switch Button to ensure it is in the correct 12V jump start mode. The device will automatically detect the battery voltage.
- Start Vehicle: Once the display indicates readiness, start your vehicle's engine.
- Power Off: After the vehicle starts, disconnect the clamps from the battery terminals (negative first, then positive) and power off the JC400.
ConnectMax Technology: The JC400 features exclusive ConnectMax technology, which automatically detects impedance between the clamp and the battery. This optimizes starting performance by up to 30%, especially useful when battery terminals have accumulated contaminants (oxidation, rust, oil, dust) that can lead to poor contact.
BOOST Start Function: For completely exhausted batteries (as low as 0V), the JC400 is equipped with a BOOST start function. Refer to the display for instructions on activating this mode if needed.
6.2. Charging an External Battery (Charger, Maintainer, Desulfator)
The JC400 functions as a smart battery charger, maintainer, and desulfator for 6V/12V regular, 12V AGM, and 12V lithium batteries. It offers three optional output currents: 0.75A, 1A, and 2A.
