WARNING
q
Start the engine only after sitting down in the operator's seat.
q
Do not attempt to start the engine by short-circuiting the engine starting circuit. Such an act may
cause a serious bodily injury or fire.
q
Check that there are no persons or obstacles in the surrounding area, then sound the horn and start
the engine.
q
Never use starting aid fluids as they may cause explosions.
q
Exhaust gas is toxic. When starting the engine in confined spaces, be particularly careful to ensure
good ventilation.
NOTICE
q
Do not continue to crank the starting motor continu-
ously for more than 60 seconds under any circum-
stances. If the engine does not start, wait for at least 2
minutes, then repeat the procedure from Step 2.
q
Before starting the engine, check that the fuel control
dial is at the low idle (MIN) position.
q
The machine is equipped with a function to automati-
cally warm up engine cooling water temperature more
quickly and another function to protect the turbo-
charger. In a cold weather startup, the engine revolu-
tion may not change for several seconds immediately
after the startup even if fuel control dial (1) is operated.
q
If the fuel control dial is in the FULL position, the
engine will accelerate suddenly and cause damage to
the engine parts, so set it to an intermediate or low
speed position.
1. Turn fuel control dial (1) to the center position between MIN
and MAX position.
