Operator Safety
Inadequate Snow Conditions
Do not drive for prolonged periods on blacktop, gravel, or ice. Doing so could
cause irreversible track damage and lead to serious injury.
Since snow provides the only lubrication for the power slide suspension
and, on liquid cooled models, cooling for the engine, adequate snow
cover is a requirement for operation of your snowmobile. Driving in too
little snow will result in excessive wear and damage to the slide rail,
track and/or engine.
When operating on icy surfaces or hard-packed snow, avoid overheating the
slide rail and track. Lack of lubrication and cooling will cause overheating of
the slide rail and track, resulting in premature wear and failure. If frequently
operating in low cooling conditions, see your dealer for an optional wheel kit
that will reduce the wear from overheating.
Operating in Deep Snow
If the snowmobile becomes stuck in snow, clear the running board area
of snow, then step down the snow in front of the snowmobile so that
when the throttle is opened, the snowmobile will be able to climb up and
over the snow.
