OPERATION
MACHINE OPERATIONS AND CONTROLS
STARTING ENGINE
Normal Starting
WARNING
Sit down in the operator's seat before starting the engine.
Do not attempt to start the engine by short-circuiting the engine starting
circuit. Such an act may cause 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.
Exhaust gas is toxic. When starting the engine in confined spaces, be
particularly careful to ensure good ventilation.
NOTICE
Before starting the engine, check that the fuel control dial is at the low idle (MIN) position.
If the fuel control dial is at the FULL position, the engine will accelerate suddenly and cause damage to the engine parts.
Do not crank the starting motor continuously for more than 20 seconds.
If the engine does not start, wait for at least 2 minutes before trying again.
REMARK
If the engine is stopped when it is not fully warmed up and it is started again a few minutes later, there may be a delay
in the engine rotation during cranking. This is caused by fuel gas remaining inside the cylinder; it does not indicate
any abnormality. In addition, even if this phenomenon occurs, there is no problem with the reliability or durability of
the engine or other parts.
1.
Check the lock lever (1) is in the LOCK position (L). If the lock
lever is in the FREE position (F), the engine does not start.
2. Set fuel control dial (2) at the low idle (MIN) position.
If it is at the high idle (MAX) position, always change it to the
low idle (MIN) position.
