OPERATION
n
Throttle Lever
WARNING
An improperly functioning throttle lever may cause erratic
machine behavior and loss of control, which could result in
serious injury or death. If the throttle lever does not work properly,
DO NOT start the engine.
If the engine stops abruptly when the throttle lever is released:
1. Turn the ignition switch to OFF.
2. Visually inspect the throttle cable and throttle body to determine
what caused the safety switch to activate.
3. Test the throttle lever by compressing and releasing it several
times. The lever and cable must return to the idle position quickly
and completely.
4. If the throttle lever operates properly, turn the ignition switch on
and go through normal starting procedures.
5. If the engine doesn’t start, take the snowmobile to an authorized
Polaris dealer for service.
NOTE: Excessive freeplay in the throttle cable may cause the safety
switch to activate, preventing the engine from starting. If this
occurs, return the snowmobile to an authorized Polaris
dealer for service.
If an emergency exists and it’s necessary to start the engine, the throttle
safety switch and engine stop switch may be disconnected from the
wire harness. When these switches are disconnected, the ignition key
switch must be used to shut off the engine. DO NOT continue to
operate the snowmobile with the throttle safety switch disconnected.
Return the snowmobile to an authorized Polaris dealer for service as
soon as possible.
Turbo Noise (FST)
Under some conditions, when the throttle lever is released the boost
pressure dump valve will release pressure, and you may hear the sound
of escaping air. This is a normal occurrence on turbo-charged models.
