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.
TIP
The engine can be started after it stops.
ESU10332
Throttle override system
(T.O.R.S.)
WARNING
EWS00041
If the T.O.R.S. is activated, make sure that
the cause of the malfunction has been cor-
rected and that the engine can be operated
without a problem before restarting the
engine. Continuing to operate with a mal-
function could cause loss of control or
damage.
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.)
