Riding your snowmobile
Getting to know your snowmobile
A snowmobile is a rider active vehicle, and
your riding position and your balance are the
two basic factors of maneuvering your snow-
mobile.
Riding your snowmobile requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Riding your new snowmobile can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the snowmo-
bile to achieve the skill necessary to enjoy
riding safely. Before operating the snowmo-
bile, read this Owner’s Manual completely
and understand the operation of the controls.
Pay particular attention to the safety informa-
tion on page 1.
Please read all warning and caution labels on
your snowmobile. Also, read the Snowmobil-
er’s Safety Handbook that is supplied with
your snowmobile.
Learning to ride your snowmobile
Before you ride, always perform the pre-oper-
ation checks listed on page 26. The short time
spent checking the condition of the snowmo-
bile will be rewarded with added safety and a
more reliable snowmobile. Always wear the
proper clothing for both warmth and to help
protect you from injury if an accident occurs.
Become familiar with operating your snowmo-
bile at low speeds, even if you are an experi-
enced rider. Do not attempt to operate at
maximum performance until you are totally fa-
miliar with the snowmobile’s handling and
performance characteristics.
The beginning operator should select a large
flat area to become familiar with the snowmo-
bile. Make sure that this area is free of obsta-
cles and other traffic. You should practice
control of the throttle and brake, and master
turning techniques in this area before trying
more difficult terrain.
Set the parking brake and follow the instruc-
tions on page 28 to start the engine. Once the
engine has warmed up, you are ready to be-
gin riding your snowmobile.
To start out and accelerate
1. With the engine idling, release the park-
ing brake.
2. Apply the throttle slowly and smoothly.
The V-belt clutch will engage and you will
start to accelerate.
WARNING
EWS00210
The operator should always keep both
hands on the handlebar. Never put your
feet outside the running boards. Avoid
