Operation
52
Improper riding techniques such as abrupt
throttle changes, excessive braking, incorrect
body movements, or too much speed for the
sharpness of the turn may cause the snow-
mobile to tip.
If your snowmobile begins to tip while turning,
lean more into the turn to regain balance. If
necessary, gradually let off on the throttle or
steer to the outside of the turn.
Remember:
Avoid higher speeds until you are thoroughly
familiar with the operation of your snowmo-
bile.
Riding uphill
WARNING
EWS00231
Operation on slopes can lead to loss of
control if proper techniques are not used.
Follow these instructions to reduce your
risk of an accident. Do not try steeper or
more difficult inclines until you have de-
veloped your skill on gentle slopes.
You should practice first on gentle slopes. Try
more difficult climbs only after you have de-
veloped your skill. As you approach a hill, ac-
celerate before you start the climb, and then
reduce the throttle to prevent track slippage. It
is also important to keep your weight on the
uphill side at all times. On climbs straight up
the hill, this can be accomplished by leaning
forward and, on steeper inclines, standing on
the running boards and leaning forward over
the handlebar. (Also see Traversing a
slope.)
Slow down as you reach the crest of the hill,
and be prepared to react to obstacles, sharp
drops, or other vehicles or people which may
be on the other side. If you are unable to con-
tinue up a hill, do not spin the track. Stop the
engine and set the parking brake. Then pull
the rear of the snowmobile around to point the
snowmobile back down the hill. When the
snowmobile is pointed downhill, mount your
snowmobile from the uphill side. Restart the
engine, release the parking brake, and de-
scend the hill.
Riding downhill
WARNING
EWS00240
Use extra caution when applying the brake
during a descent. Excessive braking will
cause the drive track to lock, causing a
loss of control.
When riding downhill, keep speed to a mini-
mum. It is important to apply just enough
throttle to keep the clutch engaged while de-
scending the hill. This will allow you to use en-
gine compression to help slow the
snowmobile, and to keep the snowmobile
from rolling freely down the hill. Also apply the
brake frequently, with light pressure.
