Hard-packed snow

It can be more difficult to negotiate on
hard-packed snow as both the skis and
drive track do not have as much traction as
when the snowmobile is operated on fresh
snow. Avoid rapid acceleration, turning,
and braking.

Operation on surfaces other than
snow or ice

Operation of your snowmobile on surfaces
other than snow or ice should be avoided.
Operation under such conditions will dam-
age or result in rapid wear of the ski run-
ners, drive track, slide runners, and drive
sprockets. Operation of the snowmobile on
the following surfaces should be avoided at
all times:

1. Dirt 
2. Sand 
3. Rocks 
4. Grass 
5. Bare pavement

Other surfaces that should be avoided for
the sake of drive track and slide runner life
are:

1. Glare ice surfaces 
2. Snow mixed with a lot of dirt and sand

All of the above surfaces have one thing in
common in regard to drive track and slide
runners; little or no lubricating ability. Drive
track and all slide rail systems require
lubrication (snow or water) between the
slide runners and the slide metal. In the
absence of lubrication, the slide runners
will rapidly wear and in severe cases, liter-
ally melt away, and the drive track will be
subject to damage or failure.
Also traction aids such as studs, cleats,
etc., may cause further track damage or
failure.

WARNING

Drive track damage or failure could
result in loss of braking ability and
snowmobile control, which could cause
an accident. 

Always check the drive track for
damage or maladjustment before
operating the snowmobile. 

Do not operate the snowmobile if
you find damage to the drive track. 

@

CAUTION:

Ride on fresh snow frequently. Operat-
ing on ice or hard-packed snow will rap-
idly wear the slide runners.
