SAFETY INFORMATION
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 operating
1. Read the Owner’s Manual and all labels before oper-
ating this snowmobile. Become familiar with all of the
operating controls and their function. Consult a
Yamaha dealer about any control or function you do
not understand.
2. 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.
3. SXV60 and SXV60ER are designed to carry the
OPERATOR ONLY.
Passengers are prohibited. Carrying a passenger
can cause loss of control.
4. Do not operate the snowmobile after drinking alcohol
or taking drugs. Your ability to operate the snowmobile is reduced by the influence of alcohol or drugs.
5. For safety and proper care of the snowmobile, always
perform the pre-operation checks on pages 6-1–6-9
before starting the engine. Check the throttle, brake,
and steering for proper operation every time before
starting the engine. Make sure that the throttle lever
moves freely and it returns to the home position when
it is released.
6. 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.
3-1
Page 15
7. 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.
8. Handle fuel with care; it is HIGHLY FLAMMABLE.
Never add fuel when the engine is running or hot.
●
Allow the engine to cool for several minutes after
running.
Use an approved fuel container.
●
Fill the fuel tank outdoors with extreme care.
●
Never remove the fuel cap indoors. Never fill the
fuel tank indoors.
Never refuel while smoking or in the vicinity of an
●
open flame.
Make sure that the fuel tank cap is closed securely
●
after refueling. Wipe up any spilled fuel immediately.
9. If you swallow some gasoline, inhale a lot of gasoline
vapor, or get some gasoline into your eyes, see your
doctor immediately. If any gasoline spills on your skin
or clothing, immediately wash your skin with soap
and water, and change your clothes.
10. Wear protective clothing. Wear an approved 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.
Operation
1. Do not run the engine indoors, except when starting
the engine to transport the snowmobile in or out of
the building. Open the outside doors; exhaust fumes
are dangerous.
2. 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.
3-2
Page 16
3. 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.
4. Avoid operating on glare ice, or on snow which has a
lot of dirt or sand mixed in. Operation under such
conditions will damage or result in rapid wear of ski
runners, drive track, slide runners, and drive sprockets.
5. 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.
6. Many surfaces such as ice and hard-packed 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.
Maintenance and storage
1. Do not leave the snowmobile on its left side for an
extended period of time. Fuel may leak out from the
fuel breather hose.
2. Modifications made to the snowmobile not approved
by Yamaha, or the removal of original equipment may
render your snowmobile unsafe for use that may
cause severe personal injury. Modifications may also
make the snowmobile illegal to use.
3. 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.
4. Always refer to the “STORAGE” section if the snow-
mobile is to be stored for an extended period.
5. Maintain or replace safety and instruction labels, as
necessary.

Break-in
There is never a more important period in the life of your
snowmobile than the break-in period. For the first
10 hours, approximately 200 km (125 mi), do not put an
excessive load on the engine. Avoid prolonged full throttle operation.
Also avoid lugging the engine, such as laborious operation in wet snow. If any abnormal condition is noticed,
such as excessive vibration or noise, consult a Yamaha
dealer.
NOTE:
@
To ensure proper engine break-in, use a 50:1 gasoline/oil
mixture when filling the fuel tank of a new snowmobile for
the first time.
For example:
10 L of gasoline per 0.2 L of oil (1 gal of gasoline per
2.6 oz of oil) equals a 50:1 mixing ratio.
(See pages 6-1–6-2 for the recommended gasoline and
oil.)

Riding your snowmobile
totally familiar with the snowmobile’s han-
dling and performance characteristics.
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
snowmobile.
Riding your snowmobile requires skills
acquired through practice over a period of
time. Take the time to learn the basic techniques well before attempting more difficult
maneuvers.
Riding your new snowmobile can be a very
enjoyable activity, providing you with hours
of pleasure. However, it is essential to
familiarize yourself with the operation of
the snowmobile to achieve the skill necessary to enjoy riding safely. Before operating
the snowmobile, read this Owner’s Manual
completely and understand the operation
of the controls.
Pay particular attention to the safety information on pages 3-1–3-3. Please read all
warning and caution labels on your snowmobile. Also, read the Snowmobiler’s
Safety Handbook that is supplied with your
snowmobile.
Set the parking brake and follow the
instructions on pages 7-1–7-2 to start the
engine. Once the engine has warmed up,
you are ready to begin riding your snowmobile.
To start out and accelerate
1. With the engine idling, release the
parking brake.
2. Apply the throttle slowly and smoothly.
The V-belt clutch will engage and you
will start to accelerate.
WARNING
@
The operator should always keep both
hands on the handlebar. Never put your
feet outside the running boards. Avoid
high speeds until you have become
thoroughly familiar with your snowmobile and all of its controls.
@
Braking
When slowing down or stopping, release
the throttle and apply the brake gently—not
suddenly.
Learning to ride your snowmobile
Before you ride, always perform the preoperation checks listed on pages 8-1–8-3.
The short time spent checking the condition of the snowmobile 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 snowmobile at low speeds, even if you are an
experienced rider. Do not attempt to operate at maximum performance until you are
WARNING
@
●
Many surfaces such as ice and hardpacked snow require much longer
stopping distances. Be alert, plan
ahead, and begin decelerating early.
●
Improper use of the brake can cause
the drive track to lose traction,
reduce control, and increase the
possibility of an accident.
@
7-5
Page 48
Tu rn in g
Riding uphill
For most snow surfaces, “body English” is
the key to turning.
As you approach a curve, slow down and
begin to turn the handlebar in the desired
direction. As you do so, put your weight on
the running board to the inside of the turn
and lean your upper body into the turn.
This procedure should be practiced at low
speeds many times, in a large flat area
with no obstacles. Once you have learned
this technique, you should be able to perform it at higher speeds or in tighter
curves. Lean more as the turn gets
sharper or is made at higher speeds.
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 snowmobile 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
snowmobile.
You should practice first on gentle slopes.
Try more difficult climbs only after you have
developed your skill. As you approach a
hill, accelerate 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 continue 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 descend
the hill.
WARNING
@
Side hills and steep slopes are not recommended for a novice snowmobiler.
@
7-6
Page 49
Riding downhill
When riding downhill, keep speed to a minimum. It is important to apply just enough
throttle to keep the clutch engaged while
descending the hill. This will allow you to
use engine 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.
WARNING
@
Use extra caution when applying the
brake during a descent. Excessive
braking will cause the drive track to
lock, causing a loss of control.
@
Traversing a slope
downhill leg on the seat and the foot of
your uphill leg on the running board. This
position will make it easier for you to shift
your body weight as needed.
Snow and ice are slippery, so be prepared
for the possibility that your snowmobile
could begin to slip sideways on the slope. If
this happens, steer in the direction of the
slide if there are no obstacles in your path.
As you regain proper balance, gradually
steer again in the direction you wish to
travel.
If your snowmobile starts to tip, steer down
the hill to regain balance.
WARNING
@
If you are unable to maintain correct
balance, and your snowmobile is going
to tip over, dismount your snowmobile
immediately on the uphill side.
@
Ice or icy surface
Operating on ice or icy surfaces can be
very dangerous. Traction for turning, stopping, and starting is much less than that on
snow.
WARNING
@
Traversing slopes is not recommended
for a novice snowmobiler.
@
Traversing a slope requires you to properly
position your weight to maintain proper balance. As you travel across the slope, lean
your body to position your weight towards
the uphill side. A recommended riding
position is to kneel with the knee of your
WARNING
@
When you have to operate on ice or icy
surfaces, drive slowly and cautiously.
Avoid accelerating, turning, and braking
rapidly. Steering is minimal and uncontrolled spins are an ever-present danger.
@
7-7
Page 50
Hard-packed snow
It can be more difficult to negotiate on
hard-packed snow as both the skis and
drive track do not have as much traction as
when the snowmobile is operated on fresh
snow. Avoid rapid acceleration, turning,
and braking.
Operation on surfaces other than
snow or ice
Operation of your snowmobile on surfaces
other than snow or ice should be avoided.
Operation under such conditions will damage or result in rapid wear of the ski runners, drive track, slide runners, and drive
sprockets. Operation of the snowmobile on
the following surfaces should be avoided at
all times:
1. Dirt
2. Sand
3. Rocks
4. Grass
5. Bare pavement
Other surfaces that should be avoided for
the sake of drive track and slide runner life
are:
1. Glare ice surfaces
2. Snow mixed with a lot of dirt and sand
All of the above surfaces have one thing in
common in regard to drive track and slide
runners; little or no lubricating ability. Drive
track and all slide rail systems require
lubrication (snow or water) between the
slide runners and the slide metal. In the
absence of lubrication, the slide runners
will rapidly wear and in severe cases, literally melt away, and the drive track will be
subject to damage or failure.
Also traction aids such as studs, cleats,
etc., may cause further track damage or
failure.
WARNING
@
Drive track damage or failure could
result in loss of braking ability and
snowmobile control, which could cause
an accident.
●
Always check the drive track for
damage or maladjustment before
operating the snowmobile.
●
Do not operate the snowmobile if
you find damage to the drive track.
@
CAUTION
@
:
Ride on fresh snow frequently. Operating on ice or hard-packed snow will rapidly wear the slide runners.

ESU00251
Maximizing drive track life
Recommendations
Track tension
During initial break-in, the new drive track will tend to
stretch quickly as the track settles. Be sure to correct the
track tension and alignment frequently. (See pages
8-23–8-25 for adjustment procedures.) A loose track can
slip (ratchet), derail or catch on suspension parts causing severe damage. Do not overtighten the drive track,
otherwise it may increase the friction between the track
and the slide runners, resulting in the rapid wear of both
components. Also, this may put an excessive load on the
suspension components, resulting in component failure.
Marginal snow
The drive track and the slide runners are lubricated and
cooled by snow and water. To prevent the drive track and
slide runners from overheating, avoid sustained highspeed usage in areas such as icy trails, frozen lakes and
rivers that have minimal snow coverage. An overheated
track will be weakened internally, which may cause failure or damage.
Off-trail riding
Avoid off-trail riding until there is sufficient snow coverage. It generally takes several feet of snow to provide a
good overall base to properly cover debris, such as
rocks, logs, etc. If snow coverage is not sufficient, stay on
trails to avoid impact damage to the drive track.
Studded track
In general, track life will be shortened when studs are
installed. Drilling stud holes into the drive track will cut
the internal fibers, which weakens the track. Avoid spinning the drive track. Studs may catch on an object and
pull out of the track, leaving tears and damage around
the already weakened area. To minimize possible damage, consult your stud manufacturer for installation and
stud pattern recommendations.
Yamaha does not recommend track studding.

Transporting
When transporting your snowmobile on a trailer or in a
truck, observe the following recommendations to help
protect it from damage:
Make sure that the fuel level in the fuel tank is lower
●
than the bottom of the carburetors. Otherwise, the
vibration and bumps from the road surface could
make it possible for fuel to flow through the carburetors into the crankcase. This can result in “hydrostatic
lock,” a condition where the engine cannot rotate
because of fuel accumulated in the engine. Severe
engine damage can result from hydrostatic lock.
When possible, the fuel tank should be empty during
transportation, especially if the trip will be longer than
30 minutes.
If transporting the snowmobile in an open trailer or
●
truck, put a tight fitting cover on the snowmobile. A
cover specifically designed for your snowmobile is
best. This will help keep foreign objects out of the
cooling vents in the shroud, and also help protect the
snowmobile against damage from debris on the road.
If transporting the snowmobile in an open trailer or
●
truck in areas where road salt is used, coat metal
suspension surfaces lightly with oil or other protectant. This will help protect against corrosion. Be
sure to clean the snowmobile when you get to your
destination to remove any corrosive salts.

Checking the spark plug
The spark plug is an important engine component and is
easy to inspect. The condition of the spark plug can indicate the condition of the engine. Check the coloration on
the white porcelain insulator around the center electrode.
The ideal coloration at this point is a medium to a light
tan color for a snowmobile that is being ridden normally.
If a spark plug shows a distinctly different color, there
could be something wrong with the engine. For example,
a very white center electrode porcelain color could indicate an intake track air leak or carburetion problem for
that cylinder. Do not attempt to diagnose such problems
yourself. Instead, take the snowmobile to a Yamaha
dealer for inspection and possible repairs. You should
periodically remove and inspect the spark plug because
heat and deposits will cause a spark plug to slowly break
down and erode. Consult a Yamaha dealer before changing to a different type of spark plug.

Specified spark plug:
BR9ES (NGK)
Spark plugs are produced in several different thread
lengths. The thread length or reach is the distance from
the spark plug gasket seat to the end of the threaded
portion. If the reach is too long, overheating and engine
damage may result. If the reach is too short, spark plug
fouling and poor performance may result. Also, if the
reach is too short, carbon will form on the exposed
threads resulting in combustion chamber hot spots and
thread damage. Always use a spark plug with the specified reach.
Spark plug reach a:
19.0 mm (0.75 in)
Before installing any spark plug, measure the electrode
gap with a wire thickness gauge and adjust to specification.
Spark plug gap b:
0.7–0.8 mm (0.028–0.031 in)
When installing the spark plug, always clean the gasket
surface. Wipe off any grime from the threads and tighten
the spark plug to the specified torque.
Spark plug tightening torque:
20 Nm (2.0 m·kgf, 14 ft·lb)

Adjusting the high altitude settings
Operating at high altitude reduces the performance of a
gasoline engine to about 3% for every 305 m (1,000 ft) of
elevation. This is because there is less air as altitude
increases. Less air means less oxygen available for combustion.
Your snowmobile can be adjusted to overcome most of
the problems found in high altitude riding. Carburetor
adjustments are the most important. Less air at high altitude makes the air/fuel ratio too rich, which can cause
poor performance. Common problems are hard starting,
bogging, and plug fouling. Follow the Main Jet Setting
chart which is available at a Yamaha dealer carefully.
Proper carburetion adjustments will correct the air/fuel
ratio.
Remember:
less air at higher altitude means there is
less horsepower available, even with proper carburetion.
Expect acceleration and top speed to be reduced at
higher altitudes.
To overcome operating with less power at high altitudes,
your snowmobile may also require different settings for
the drive chain gears and V-belt clutch to avoid poor performance and rapid wear. If you plan to operate your
snowmobile at an altitude different from the area where
you bought it, be sure to consult a Yamaha dealer. They
can tell you if there are any changes necessary for the
altitude where you plan to ride.
CAUTION
@
:
The drive chain gears and V-belt clutch should be
adjusted when operating over a high altitude of
900 m (3,000 ft). Consult a Yamaha dealer.

STORAGE
Long-term storage requires some preventive procedures to guard against deterioration.
1. Cleaning
Thoroughly clean the snowmobile, inside
and out, to remove the corrosive salts and
acids that can accumulate. Use Yamaha
Mud, Grease, and Engine Cleaner, or an
equivalent product, to loosen mud, grease,
and grime. Wash with mild soap, then rinse
and dry completely.
2. Lubrication
Lubricate moving parts, suspension linkage, and pivot points. Use the grease or
lubricant specified in the MAINTENANCE
section, or Yamaha Lube-Zall general-purpose lubricant. Proper lubrication fights
corrosion while it reduces friction.
bustion chamber and crankshaft from
corrosion. An alternate method is to
remove the carburetor silencer and squirt
oil into the carburetor throats while the
engine is running.
CAUTION
@
:
Do not attempt to store the snowmobile
by simply starting the engine occasionally during the storage period. This can
cause more harm than good! Moisture
and acids form during combustion
which can actually increase the chance
for corrosion damage during the storage period.
@
5. Protection
Apply a coat of wax to painted surfaces.
Apply suitable protectants to the exterior of
the engine, drive track, and to other metal,
plastic, and rubber parts.
3. Fuel system preparation
Add Yamaha Fuel Stabilizer and Conditioner, or an equivalent stabilizer, to the
fuel tank to help prevent fuel oxidation and
gum and varnish deposits, and to inhibit
corrosion in the fuel system and carburetor. In areas where oxygenated fuel (gasohol) is used, completely drain the fuel
system. Ask a Yamaha dealer if further
information is needed.
4. Engine
Proper storage of the engine is essential to
prevent costly rust and corrosion damage
to internal engine components. This is
more important in areas where oxygenated
fuel (gasohol) is used, because the alcohol
content in the fuel increases the chance for
water to enter the engine. Use Yamaha
Stor-Rite Engine Fogging Oil, or an equivalent fogging oil, to protect both the com-
6. Battery
For SXV60ER/VT60
Remove the battery from the snowmobile
and check the fluid level. Add only distilled
water if necessary. (See the “Battery—
Replenishing the battery fluid” section on
page 8-28 for instructions.) After checking
the fluid level, fully charge the battery.
Store it in a cool, dry place that is above
0 °C (32 °F), but less than 30 °C (90 °F).
Check the condition of the battery with a
hydrometer once a month, and charge it as
necessary.

WARNING
@
Never smoke around the battery
●
while it is being charged. Sparks
may ignite the hydrogen gas created
by the battery.
Never connect the battery to or dis-
●
connect it from the snowmobile
while it is being charged. Sparks
may ignite the hydrogen gas created
by the battery.
Make sure that the battery terminals
●
are tight and that the battery vent
tube is properly routed and is
securely attached to the battery.
@
CAUTION
@
:
Do not charge the battery quickly.
Charge the battery for 10 hours at
2.0 amperes.
@
7. Drive track
Loosen the drive track and block up the
chassis so that the track is suspended
above the ground.
Returning to service after storage
When returning your snowmobile to service, reinstall the V-belt and adjust the
drive track. Before installing the battery,
have a Yamaha dealer inspect and fully
charge it. Install the battery, and make sure
that the battery vent tube is properly
installed and that there are no kinks in it.
Remove the spark plugs and clean or
replace them if necessary. Perform all
other pre-operation and seasonal maintenance checks listed in the periodic maintenance chart.
For peak performance, it is recommended
that you have your snowmobile checked
and tuned by a Yamaha dealer. They have
the experience and training to help you get
the maximum performance and use of your
Yamaha snowmobile.
8. V-belt
Remove the V-belt and store separately.
9. Storage
Store the snowmobile in a dry, well-ventilated place out of direct sunlight. Put a fabric cover over the snowmobile, preferably
one that is designed for it. Do not use a
plastic or vinyl cover—condensation could
be trapped underneath which could
increase the chances of rusting.
