Attention! When working with electrical equipment, certain safety precautions should always be observed:
- It is not permissible to leave the ignition on for a long time with the engine off.
- Under no circumstances should you disconnect the wires from the battery while the engine is running.
- When connecting wires from an auxiliary power source during emergency engine starting, polarity must be strictly observed.
- The negative cable should always be disconnected from the battery first and connected last to avoid a short circuit if the tool accidentally touches the ground when loosening/tightening the positive terminal clamp.
