Remove all dirt from the surface of the lens of the headlamps and working lamps, and check that they light

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 any pedals, and check that
the pedals work properly.
Adjust the operator's seat to a position for easier operation. Check that there is no damage or wear to the
seat belt or mounting clamps.
Check that the gauges work properly, check the angle of the mirror, and check that the control levers are all
at NEUTRAL position.
Before starting the engine, check that lock lever (1) is in
LOCK position (L).
Adjust the mirrors to have a good rear view from the oper-
ator's seat.

PRECAUTIONS WHEN STARTING ENGINE

The machine may suddenly move off and this may lead to serious personal injury or death. Always observe the
following.
Start the engine only while sitting down in the operator's seat.
When starting the engine, sound the horn as a warning.
Prohibit anyone other than the operator to get on the machine.
Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause fire, serious
personal injury or death.

IN COLD WEATHER

If the warm-up operation is not performed thoroughly, and the work equipment is operated, the reaction of
the work equipment to the operation of the control levers and pedals will be slow and the movement of it
may not be what the operator intended. Be sure to perform the warm-up operation. Particularly in a cold
weather, be sure the warming-up operation is completed.
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.
