STARTING SWITCH
Starting switch is used to start or stop the engine.
(A): OFF position
The key can be removed from the starting switch, the electrical
current to the electrical system is cut, and the engine stops. In
addition, the parking brake is applied automatically.
(B): ON position
Electric current flows through the charging and lamp circuits.
Keep the switch at this position while the engine is running.
When the ambient temperature is low during engine startup,
the engine preheating pilot lamp lights up and engine preheat-
ing starts automatically.
This preheating time depends on the ambient temperature during engine startup.
When the engine preheating pilot lamp lights up, wait for a while. When it goes out, then turn the starting key to
the START position.
(C): START position
This is the position to start the engine. Hold the key at this position while cranking the engine. Release your
hand off the key immediately after the engine has been started. The key returns to ON position (B).
(D): Manual preheat position
In cold weather, you can increase the engine preheating time longer than the automatic preheating time. To in-
crease it, turn the starting switch key to this position.
When you release your hand, the switch returns to position (A). Immediately turn the key to position (C) and
start the engine.
