STARTING ENGINE
• When the starter switch (2) is shifted to the
ON position, the engine stop solenoid (4)
drives the governor stop lever to the OPERA-
TION position. Should an error develop in the
electric system, this arrangement stops the
engine operation that functions as a fail-safe
mechanism.
• If the starter switch (2) is shifted to the START
position with the safety lock lever (5) at the
LOCK position, the starting signal flows in the
starter (9) and the engine starts. If the safety
lock lever (5) is at the FREE position, the start-
ing signal to the starter (9) is cut off and the
engine cannot start.
• Since the fuel adjust lever (11) is linked with
the fuel adjust motor (12), the engine is
driven at the speed set on the fuel adjust lever
(11).
ENGINE STOP
• If you shift the starter switch (2) to the OFF
position, the engine stop solenoid (4) drives
the governor stop lever to the STOP position
to stop the engine.
