Key Switch
Key switch (a) is used to activate the following functions:

OFF - This position allows you to insert and
remove the key. The engine is shut down (or
remains off) and there is no electrical current to any
of the electrical system switches (except for work
lamps).
•
HEAT - Hold the key at this position to preheat the
engine for cold-weather starting as required. The
key returns to the OFF position when released.
•
ON - This position allows the engine to remain
running (if already started) and also allows
electrical current to all of the various electrical
system switches.
•
START - Hold the key at this position to start the engine, then immediately release it after the engine has
started. The key returns to the ON position when released.

and counterclockwise to decrease speed.
•
