OPERATING INSTRUCTIONS
Propulsion
Depressing throttle lever increases
engine RPM causing the drive pulley
to engage. Depending on models en-
gine RPM must be between 2500 and
4200 before drive pulley engagement
will occur.
Outer sheave of drive pulley moves
toward inner sheave, forcing 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 move-
ment.
The result is an optimized
speed ratio between engine RPM and
the speed of the vehicle at any time.
Power is transferred to the track
through the chaincase or gearbox
and drive axle.
Turning
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.
Stopping
Before riding your snowmobile, you
should understand how to stop it.
This is done by releasing the throttle
and gradually depressing the brake
lever on the left side of the handlebar.
In an emergency, you may stop your
vehicle by pressing the engine cut-out
switch located near the throttle control
and applying the brake.
Remember, a snowmobile cannot
”stop on a dime”. Braking character-
istics vary with deep snow, packed
snow or ice. If the track is locked dur-
ing hard braking, skidding may result.
Starting the engine
Check throttle lever operation.
Ensure that the engine cut out switch
is in the ON position.
Ensure that the tether cord cap is in
position and that the cord is attached
to your clothing eyelet.
Choke equipped vehicles
Initial cold starting: Do not operate
the throttle lever with the choke lever
on.
When temperature is below - 10°C
Move the choke lever to position 2 and
start the engine. As soon as the en-
gine starts move the lever to position
1. After a few seconds (max.10 sec-
onds) move the choke lever to OFF po-
sition.
NOTE: In severe cold weather, colder
than - 20°C you may need to flip choke
lever from OFF to position 1 a couple
of times once engine is started.
1. OFF
2. Position 1
3. Position 2
When temperature is above - 10°C
Move the choke lever to position 1.
Grab the handle firmly and start the en-
gine or electric starter if it is equipped.
As soon as the engine starts move the
choke lever to OFF.
4-tec models
