WARNING
• Start the engine only while sitting on the operator's seat.
• Do not attempt to start the engine by short-circuiting the engine starting circuit. This may cause
fire, serious personal injury or death.
• Check that there is no person or obstacle in the area around the machine, then sound the horn and
start the engine.
• Exhaust gas is toxic. When starting the engine in confined spaces, be particularly careful to ensure
good ventilation.
• Do not approach the exhaust pipe outlet of the engine while the engine is running or just after it is
stopped.
Also, keep the combustible materials away from the exhaust pipe outlet.
NOTICE
• Do not turn the starting motor continuously for more
than 60 seconds in any case. If the engine does not
start, wait for approximately 2 minutes, then repeat the
procedure from step 2.
• When starting the engine, if the fuel control dial is at
High idle (MAX) position, the engine will accelerate
suddenly and cause damage to the engine parts.
Before starting the engine, check that the fuel control
dial (1) is at Low idle (MIN) position.
• This machine is equipped with the automatic warm-up
function to heat the coolant more quickly and the tur-
bo protect function to protect the turbocharger. In a
cold weather startup, the engine revolution may not
change for several seconds immediately after the
startup even if the fuel control dial (1) is operated.
• Even if the engine is started with fuel control dial (1) in
a position other than Low idle (MIN) position, the en-
gine speed is set to low idle.
You can change the engine speed by turning the fuel
control dial (1) to Low idle (MIN) position and then
turning it toward High idle (MAX) position.
1.
Turn the fuel control dial (1) to Low idle (MIN) position.
When the dial is in High idle (MAX) position, be sure to set
it to Low idle (MIN) position.
