Operator Safety
Stay Away From Moving Parts
Be alert when riding, and remain properly seated to stay clear of the
track. Your snowmobile is propelled by a revolving track that must be
partially exposed for proper operation. Serious injuries may result if
hands, feet, or clothing become entangled in the track.
If fingers or clothing contact the moving parts of an engine,
serious injury can result. Always stop the engine before
attempting adjustments.
Never attempt adjustments with the engine running. Turn off the
ignition, raise the hood, make the adjustment, secure shields and
guards, secure the hood, and then restart the engine to check its
operation.
10
Never hold the snowmobile up or stand
behind it while warming up the track. A
loose track or flying debris could cause
serious personal injury or death.
We recommend having your dealer perform
track service and alignment procedures.
