Throttle override system
(T.O.R.S.)
EWS00041
WARNING
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
83 for the clutch engagement speed.)
