SAFETY MACHINE OPERATION

SAFETY MACHINE OPERATION

STARTING ENGINE

If there is a warning tag hanging from the work equipment con-
trol lever, do not start the engine or touch the levers (1).
DANGER - Do NOT operate
When this tag is not being used, keep it in the storage com-
partment.

CHECKS BEFORE STARTING ENGINE

Carry out the following checks before starting the engine at the beginning of the day's work.
Remove all dirt from the surface of the window glass to ensure a good view.
Remove all dirt from the surface of the lens of the front lamps and working lamps, and check that they light up
correctly.
Check the coolant level, fuel level, and oil level in engine oil pan, check for clogging of the air cleaner, and
check for damage to the electric wiring.
Adjust the operator's seat to a position where it is easy to carry out operations, and check that there is no dam-
age or wear to the seat belt or mounting clamps.
Check that the gauges work properly, check the angle of the lights and working lamps, and check that the con-
trol levers are all at the neutral position.
Before starting the engine, make sure that the safety lock lever is in the LOCK position.
Adjust the mirrors so that the rear of the machine can be seen clearly from the operator's seat.
When adjusting, see "Rear view Mirrors ( 3-72 )".
Check that there are no persons or obstacles above, below, or in the area around the machine.

SAFETY RULES FOR STARTING ENGINE

When starting the engine, sound the horn as a warning.
Start and operate the machine only while seated.
Do not allow anyone apart from the operator to ride on the machine.
Do not attempt to start the engine by short-circuiting the engine starting circuit. Such an act may cause a seri-
ous bodily injury or fire.

STARTING ENGINE IN COLD WEATHER

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.
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 and cause the battery to explode.
Before charging or starting the engine with a different power source, melt the battery electrolyte and check that
there is no leakage of electrolyte before starting.
