PRODUCT OVERVIEW

Indicators

Battery - (Figure 5, (1)) - Your driven machine
may have a battery indicator that comes on if
there is a problem in the charging system. This
indicator does not indicate whether the battery is
discharged. See Troubleshooting Chart on
page 79.
Heat - If your engine has an inlet air heater, it may
have a heat indicator that lights when the inlet air
heater is activated. Follow the instructions
provided by the driven machine manufacturer for
the operation of this indicator.

Controls

Key Switch
If your engine is equipped with electric start it
may have a three position key switch - OFF, ON,
and START. See Figure 5 for an illustration of a
typical key switch.
CAUTION
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
exhaust system, to cool slightly before
the engine itself is shut down.

will be in when the engine is running. When the
engine is not running, use this position to
energize the optional devices such as indicators
or electric fuel pump.

configurations, you cannot turn the key to the
START position without first returning the key to
the OFF position.
