Safety information
ESU10203
As the vehicle’s owner, you are responsible
for the safe and proper operation of your
snowmobile. When you ride your snowmobile, you must know and use the following for
your safety. Severe injury or death may result
if you ignore any of the following.
Before you operate your snowmobile
● Read the Owner’s Manual and all labels.
Become familiar with all of the operating
controls and their function. Consult a
Yamaha dealer about any control or function you do not understand.
● Wear protective clothing. Wear an ap-
proved helmet, and a face shield or goggles. Also, wear a good quality snowmobile
suit, boots, and a pair of gloves or mittens
that will permit use of your thumbs and fingers for operation of the controls.
● Do not operate the snowmobile after or
while drinking alcohol or taking drugs. Your
ability to operate the snowmobile is reduced by the influence of alcohol or drugs.
Prepare your snowmobile
● Perform the pre-operation checks each
time you use the vehicle to make sure it is
in safe operating condition. Failure to inspect or maintain the vehicle properly increases the possibility of an accident or
equipment damage. See page 33 for a list
of pre-operation checks.
● Apply the parking brake before starting the
engine. Never drive the snowmobile with
the parking brake applied. This may overheat the brake disc and reduce braking ability.
While using your snowmobile
● This snowmobile was not manufactured for
use on public streets, roads, or highways.
Such use is prohibited by law, and you
could collide with another vehicle.
● Be careful where you ride. There may be
obstacles hidden beneath the snow. Stay
on established trails to minimize your exposure to hazards. Ride slowly and cautiously
when you ride off of established trails. Hitting a rock or stump, or running into wires
could cause an accident and injury.
● This snowmobile is not designed for use on
surfaces other than snow or ice. Use on dirt,
sand, grass, rocks, or bare pavement may
cause loss of control and may damage the
snowmobile.
● Always ride with other snowmobilers when
going on a ride. You may need help if you
run out of fuel, have an accident, or damage
your snowmobile.
● Many surfaces such as ice and hardpacked
snow require much longer stopping distances. Be alert, plan ahead and begin decelerating early. The best braking method on
most surfaces is to release the throttle and
apply the brake gently—not suddenly.
Avoid carbon monoxide poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide
can cause headaches, dizziness, drowsiness,
nausea, confusion, and eventually death.
Carbon monoxide is a colorless, odorless,
tasteless gas which may be present even if
you do not see or smell any engine exhaust.
Deadly levels of carbon monoxide can collect
rapidly and you can quickly be overcome and
5
Safety information
be unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or
days in enclosed or poorly-ventilated areas. If
you experience any symptoms of carbon
monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL
TREATMENT.
● Do not run the engine indoors. Even if you
try to ventilate engine exhaust with fans or
open windows and doors, carbon monoxide
can rapidly reach dangerous levels.
● Do not run the engine in poorly ventilated or
partially enclosed areas such as barns, garages, or carports.
● Do not run the engine outdoors where en-
gine exhaust can be drawn into a building
through openings such as windows and
doors.
Genuine Yamaha Accessories
Choosing accessories for your snowmobile is
an important decision. Genuine Yamaha Accessories, which are available only from a
Yamaha dealer, have been designed, tested,
and approved by Yamaha for use on your
snowmobile. Many companies with no connection to Yamaha manufacture parts and accessories or offer other modifications for
Yamaha vehicles. Yamaha is not in a position
to test the products that these aftermarket
companies produce. Therefore, Yamaha can
neither endorse nor recommend the use of
accessories not sold by Yamaha or modifications not specifically recommended by
Yamaha, even if sold and installed by a
Yamaha dealer.
Maintenance and storage
● When laying the snowmobile on its side for
maintenance, use a suitable stand to keep
it in a stable and level position.
● Do not leave the snowmobile on its left side
for an extended period of time. Fuel may
leak out from the fuel breather hose.
● Do not allow anyone to stand behind the
snowmobile when starting, inspecting, or
adjusting the snowmobile. A broken track,
track fittings, or debris thrown by the track
could be dangerous to the operator or bystanders.
● Modifications made to the snowmobile not
approved by Yamaha, or the removal of
original equipment may render your snowmobile unsafe for use, which may cause severe personal injury. Modifications may
also make the snowmobile illegal to use.
● Never store the snowmobile with fuel in the
fuel tank inside a building where ignition
sources are present such as hot water and
space heaters, an open flame, sparks,
clothes dryers, and the like. Allow the engine to cool off before storing the snowmobile in an enclosed space.
