Powder Snow Operation
Moveable hood closures are included on some Polaris snowmobiles.
They are normally left open and are located on the front upper and
lower hood openings. If operating in deep snow or in extreme cold
conditions (below -20_F), Polaris recommends closing the upper hood
closure.
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 machine.
Driving in too little snow will result in excessive wear and damage to
the slide rail, track and/or engine.
If the machine becomes stuck in snow, clear the running board area of
snow, then step down the snow in front of the machine so that when
the throttle is opened, the snowmobile will be able to climb up and
over. You may then mount the machine and continue riding.
Do not drive for prolonged periods on blacktop, gravel, or ice.
Doing so could cause irreversible track damage and lead to serious
personal injury.
WARNING
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.
