RIDING THE VEHICLE
Before venturing on the trails, operate the snowmobile in a restricted
flat area until you are completely familiar with its operation and feel
comfortable that you can safely tackle a more demanding task. Have
an enjoyable and safe ride.
Principle of Operation
Propulsion
Depressing throttle lever increases engine RPM causing the drive
pulley to engage. Depending on models, engine RPM must be be-
tween 2500 and 4200 before drive pulley engagement will occur.
Outer sheave of drive pulley moves toward inner sheave, forcing the
drive belt to move upward on the drive pulley and simultaneously
forcing the sheaves apart on the driven pulley.
The driven pulley senses the load on the track and limits the belt
movement. The result is an optimized speed ratio between engine
RPM and the speed of the vehicle at any time.
WARNING
Never operate engine without belt guard securely installed or,
with hood or access/side panels open or removed.
Power is transferred to the track through the chaincase or gearbox
and drive axle.
WARNING
Always use a wide-base snowmobile mechanical stand to
properly support vehicle during any track verification. Slowly
accelerate engine in order to rotate track at very low speed
when it is not on ground.
Tu rnin g
Handlebar controls the steering of the vehicle. As the handlebar is
rotated to right or left, the skis are turned right or left to steer the
snowmobile.
