If the engine doesn't start, take the snowmobile to an authorized Polaris dealer for service. Tip: 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. Turbo Noise 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. 81

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 speed limits at 2400 RPM 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.
Tip:
Excessive freeplay in the throttle cable may cause the safety switch to acti-
vate, preventing the engine from starting. If this occurs, return the snowmo-
bile to an authorized Polaris dealer for service.
Turbo Noise
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.
