7. PRECAUTIONS DURING OPERATION WARNING: Failure to follow these safety precautions may lead to a serious accident. PRECAUTIONS IN COLD AREAS 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, and this may lead to unexpected accidents. Carry out the warming-up operation thoroughly. If the machine is not thoroughly warmed up before the control levers are operated, the reaction of the machine will be slow, and this may lead to unexpected accidents.
Operate the control levers to relieve the hydraulic pressure (raise to above the set pressure for the hydraulic circuit and release the oil to the hydraulic tank) to warm up the oil in the hydraulic circuit. This ensures good response from the machine and prevents malfunctions. If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power source. There is danger that this will ignite the battery. When charging or starting the engine with a different power source, melt the battery electrolyte and check for leakage of battery electrolyte before starting. Battery charge rate © See “14.
