The key switch for the operator’s console
illustrated in
Figure 9
has three positions - OFF,
ON, and START.
Figure 9
OFF (key straight up and down)
(Figure 9, (1))
-
When you turn the key to this position the engine
shuts down. Electric current to the gauges and
indicators is shut off. You can insert and remove
the key in this position.
ON
(Figure 9, (2))
- This is the position the key
will be in when the engine is running. When the
engine is not running, use this position to
energize the gauges, indicators, electric fuel
pump and auxiliary devices.
START
(Figure 9, 3))
- Turn the key to this
position to start the engine. As soon as the
engine starts, release the key and it will
automatically return to the ON position. Some key
switches may be equipped with a feature that
prevents you from turning the key to the START
position while the engine is running. In these
configurations, you cannot turn the key to the
START position without first returning the key to
the OFF position.
The key switch for the operator’s console
illustrated in
Figure 10
has four positions - OFF,
ON, START, and HEAT.

CAUTION
0000008en
For maximum engine life, Yanmar
recommends that when shutting the
engine down, you allow the engine to
idle, without load, for 5 minutes. This
will allow the engine components that
operate at high temperatures, such as
the turbocharger (if equipped) and
exhaust system, to cool slightly before
the engine itself is shut down.
