INSPECTION AND MAINTENANCE BEFORE STARTING ENGINE
Carry out the following checks before starting the engine at the beginning of the day's work to ensure that there is
no problem with the operation of the machine. If this inspection is not carried out properly problems may occur
with the operation of the machine, and there is danger that this may lead to serious personal injury or death.
q
Remove all dirt from the surface of the window glass to ensure a good view.
q
Carry out the “Walk-around Checks (3-158)“.
q
Remove all dirt from the surface of the lens of the front lamps and working lamps, and check that they light up
correctly.
q
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.
q
Check that there is no mud or dust accumulated around the movable parts of any pedals, and check that the
pedals work properly.
q
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.
q
Check that the gauges work properly, check the angle of the mirror, and check that the control levers are all at
the Neutral position.
q
Before starting the engine, check that lock lever (1) is in
LOCK position (L).
q
Adjust the mirrors so that the rear of the machine can be
seen clearly from the operator's seat.
When adjusting, see “Rearview Mirrors (3-182)“.
q
Check that there are no persons or obstacles above,
below, or in the area around the machine.
PRECAUTIONS WHEN STARTING ENGINE
q
Start and operate the machine only while seated.
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
Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause fire, serious
personal injury or death.
PRECAUTIONS IN COLD AREAS
q
Carry out the warming-up operation thoroughly. If the machine is not thoroughly warmed up before the control
levers or control pedals are operated, the reaction of the machine will be slow or the machine may move in a
way not expected by the operator. Particularly in cold weather, be sure to carry out the warming-up operation
thoroughly.
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 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.
