Throttle Lever

WARNING
An improperly functioning throttle lever may cause erratic snowmobile 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 carburetor/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, your authorized POLARIS dealer can perform this service.
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.
