[ECS00021]
TIP
The headlights and taillight come on after the
engine is started.
ESU10312
Throttle lever
Once the engine is running cleanly, squeez-
ing the throttle lever will increase the engine
speed and cause engagement of the drive
train. Regulate the speed of the snowmobile
by varying the throttle position. Because the
throttle is spring-loaded, the snowmobile will
decelerate, and the engine will return to idle
when it is released.
ESU10346
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 throttle valves or throttle cable malfunc-
tions during operation, the T.O.R.S. will be ac-
tivated when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection and limit the engine speed to less
than the clutch engagement speed if the throt-
tle valves fail to return to the idle position
when the throttle lever is released. (See page
81 for the clutch engagement speed.)
