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 gentlynot 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 Owners 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.

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.
8-4
Page 59
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.
10-1
Page 88
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 covercondensation could be trapped underneath which could increase the chances of rusting.
