OPERATION
STARTING SWITCH
This switch (1) is used to start the engine.
OFF position:
At this position, the starting switch key can be inserted and
removed. When the switch is turned to this position, all the
electric circuits are turned off and the engine stops.
ON position:
In this position, electric current flows in the charging and lamp
circuits.
Keep the starting switch key at the ON position while the
engine is running.
START position:
This is the position to start the engine. Hold the key at this position while cranking. Release the key immediately
after the engine has been started. The key will return to ON position when released.
HEAT position (Gauge panel specification)
Turn the starting switch key to the HEAT position when starting
in cold weather.
If the key is held at the HEAT position, the electrical heater is
heated and the glow signal lights up or glows red. If the glow
signal flashes or glows red, release the key immediately.
When the key is released, it will return to OFF, so turn it imme-
diately to the START position to start the engine.
GLOW SWITCH
This switch (2) actuates the electrical heater to warm up the
engine intake air.
OFF position: The preheating is not actuated.
AUTO position: AUTO preheating is actuated. The length of
the preheating time varies according to the
ambient temperature when the ambient tem-
perature is below approx. -5ºC.
I position: This is used when AUTO preheating is not
enough to start the engine in cold weather sim-
ply with the glows witch at the AUTO position.
When the switch is released, it will return to the
AUTO position.
II position: This is used when carrying out preheating manually without using AUTO preheating.
When the switch is released, it will return to the OFF position.
