THROTTLE LEVER

Once the engine is running cleanly, squeezing 2 of the
throttle lever 1 will increase the engine speed and cause
engagement of the drive system. Regulate the speed of the
machine by varying the throttle position. Because the
throttle is spring-loaded, the machine will decelerate, and

the engine will return to an idle when the thumb is released
3.
WARNING
Check throttle, brake, and steering for proper opera-
tion before starting engine.

THROTTLE OVERRIDE SYSTEM (T.O.R.S.)

If the carburetor or throttle cable should malfunction during
operation, release the throttle lever. The T.O.R.S. is de-
signed to interrupt the ignition and stop the engine if the
carburetor fails to return to idle when the lever is released.
WARNING
If T.O.R.S. stops the engine, 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.
