Attention! When working on electrical equipment, certain safety precautions should always be observed:
- It is unacceptable to leave the ignition on for a long time with the engine off.
- Under no circumstances should the wires be disconnected from the battery while the engine is running.
- When connecting wires from an auxiliary power source for emergency starting of the engine, 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 while loosening/tightening the positive terminal clamp.
