OPERATION

STARTING ENGINE

Start the engine only after sitting down in the operator's seat.
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.
Check that there are no persons or obstacles in the surrounding area, then sound the horn and start the engine.
Never use starting aid fluids as they may cause explosions.
Exhaust gas is toxic. When starting the engine in confined spaces, be particularly careful to ensure good ventilation.
NOTICE
Do not accelerate the engine sharply until it is warmed up.
Do not operate the starting motor continuously for more than 20 seconds.
If the engine fails to start, wait for 2 minutes or so, and then try to start again.
When starting the engine, do not depress the accelerator pedal. Even if the accelerator pedal is depressed just after the engine
is started, the engine speed is limited by the turbo protect function. After the turbo protect time, however, the engine speed
rises sharply and the turbocharger may be damaged.
