Checks before starting engine 0.
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, working lamps, and rear combination lamp, 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.
Check that there is no mud or dust accumulated around the movable parts of the accelerator pedal or brake
pedal, and check that the pedals work properly.
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. See “Adjust rear
view mirror on page 3-65“.
Check that there are no persons or obstacles above, below, or in the area around the machine.
Precautions when starting 0.
Only start and operate the machine from the seat. Never try to start the engine by hot-wiring the ignition. This
can cause fire, grave injuries or death.
When starting the engine, sound the horn as a warning.
Do not allow anyone apart from the operator to ride on the machine.
For machines equipped with a back-up alarm, check that the alarm works properly.
Precautions in cold areas 0.
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.
