Polaris 120 XC Rider's Safety Manual And Owner's Operation And Maintenance Manual page 45

The throttle safety switch is designed to stop the engine whenever all pressure is
removed from the throttle lever and the throttle cable or valves do not return to the
normal closed position.
WARNING
If the throttle lever does not work properly, do not start the engine.
4. If the throttle lever operates properly, turn the ignition switch on and go through
normal starting procedures.
5. If the engine does not start, take the snowmobile to an authorized Polaris
dealer for service.
If excessive play develops in the
throttle cable, the safety switch
may be activated, preventing
the engine from starting. Con-
tact your dealer.
If the engine does not start, and
throttle safety switch malfunc-
tion is suspected, return the ma-
chine to an authorized Polaris
dealer for service. If an emer-
gency exists and it is necessary to start the engine, the throttle safety switch and
engine stop switch may be disconnected from the wire harness.
WARNING
With the throttle safety switch and engine stop switch disconnected, the
ignition key switch must be used to shut off the engine. Do not continue to
operate the machine with the throttle safety switch disconnected. Return
the machine to an authorized Polaris dealer for service as soon as possible.
