OPERATION
STARTING IN COLD WEATHER
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 crank the starting motor continuously for more than 20 seconds.
If the engine does not start, wait for at least 2 minutes, then repeat the
procedure from Step 2.
Before starting the engine, check that the fuel control dial is in the low
idling (MIN) position.
On this machine, to protect the turbocharger, a turbo protect function is
provided. In cold weather, even if fuel control dial (1) is moved
immediately after starting the engine, the engine speed may not change
for several seconds.
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) a little toward you from the MIN
position.
2. Insert the key into starting switch (2) and turn the key to the ON
position (B).
