PRECAUTIONS FOR OPERATION
SAFETY
2-22
q
When starting the engine, sound the horn as a warning.
q
Do not allow anyone apart from the operator to ride on the machine.
q
For machines equipped with a back-up alarm, check that the alarm works properly.
PRECAUTIONS IN COLD AREAS
q
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.
q
If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power source.
There is a hazard that this will ignite the battery.
Before charging or starting the engine with a different power source, melt the battery electrolyte and check for
frost and leakage of battery electrolyte before starting.
