ESU10321
Engine overheating prevention
system
This model is equipped with a system, which
prevents overheating when the engine is
idling.
When the engine has been idling for 3 min-
utes or longer and the coolant temperature
has risen above 100 °C (212 °F), the engine
automatically stops to prevent overheating.
NOTE:
The engine can be started after it stops.
ESU10331
Throttle override system
(T.O.R.S.)
WARNING
EWS00040
●
If the T.O.R.S. is activated, make sure
that the cause of the malfunction has
been corrected and that the engine can
be operated without a problem before
restarting the engine.
●
Be sure to use the specified spark plug
and spark plug cap. Otherwise, the
T.O.R.S. will not work properly.
If the carburetors or throttle cable malfunc-
tions during operation, the T.O.R.S. will oper-
ate when the throttle lever is released.
The T.O.R.S. is designed to override the igni-
tion and limit the engine speed to less than the
clutch engagement speed if the carburetors
fail to return to the idle position when the throt-
tle lever is released. (See page 72 for the
clutch engagement speed.)
