‡ After completing operations, remove all water, snow, or mud stuck to the wiring harness, connector 1, switches, or sensors, and cover these parts. If the water freezes, it will cause malfunctions of the machine when it is next used, which may lead to unexpected accidents. ‡ If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power source.
