Safety information

ESU10204

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 in-

creases the possibility of an accident or equipment damage. See page 36 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 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.

Avoid carbon monoxide poisoning

All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nausea, confusion, and eventu-

Safety information

ally 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 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.

Throttle lever

Once the engine is running cleanly, squeezing the throttle lever will increase the engine speed and cause engagement of the drive train. Regulate the speed of the snowmobile by varying the throttle position. Because the

throttle is spring-loaded, the snowmobile will decelerate, and the engine will return to idle when it is released.

If the T.O.R.S. is activated, make sure that the cause of the malfunction has been corrected and that the engine can be operated without a problem before restarting the engine. Continuing to operate with a malfunction could cause loss of control or damage.

If the throttle valves or throttle cable malfunctions during operation, the T.O.R.S. will be activated when the throttle lever is released. The T.O.R.S. is designed to override the fuel injection and limit the engine speed to less than the clutch engagement speed if the throttle valves fail to return to the idle position when the throttle lever is released. (See page 90 for the clutch engagement speed.)

Odometer and tripmeter modes

TIP

1. Odometer/tripmeter/fuel reserve tripmeter

Odometer shows the total distance that the vehicle has run. Tripmeter A and tripmeter B show the distance traveled since they last reset. Fuel reserve tripmeter shows the distance traveled since the fuel level warning indicator and warning light came on. Pushing the “SELECT” button switches the display between the odometer mode “ODO” and the tripmeter modes “TRIP A” and “TRIP B” in the following order: ODO → TRIP A → TRIP B → ODO If the fuel level warning indicator and warning light come on (see page 18), the odometer display will automatically change to the fuel reserve tripmeter mode “TRIP F” and start counting the distance traveled from that point. In that case, push the “SELECT” button to switch the display between the various tripmeter and odometer modes in the following order: TRIP F → ODO → TRIP A → TRIP B → TRIP F To reset a tripmeter, select it by pushing the “SELECT” button, and then push the “RESET” button for at least 1 second. If you do not reset the fuel reserve tripmeter manually, it will reset itself automatically, and the display will return to the prior mode after the snowmobile has been refueled and traveled 5 km (3 mi).

Control functions

 Odometer resets and continues counting

when it reaches 99999 while riding. However on the 10th time, the odometer will lock at 99999.

 Tripmeter A and tripmeter B reset and con-

tinue counting when they reach 999.9 while riding.

Oil change tripmeter

Oil change tripmeter shows the distance traveled since the periodic oil change interval was reached. When the periodic oil change interval is reached at the initial 800 km (500 mi), then at every 4000 km (2500 mi) thereafter, the oil change tripmeter and “OIL” flash alternately in the odometer display, and the tripmeter starts counting the distance traveled from that point. When this occurs, change the engine oil as soon as possible. (See page 59 for the oil change procedure.)

 The oil change tripmeter will flash only

when the snowmobile is stopped.

 To return to the previous display mode,

push the “SELECT” button. To display the oil change tripmeter again, turn the key to the off position, then back to the on position.

Control functions

TIP

After changing the engine oil, reset the oil change tripmeter as follows.

To reset the oil change tripmeter (when the engine oil was changed after the oil change tripmeter appeared)

1. To display the oil change tripmeter, turn the key to the on position.

2. Push the “RESET” button for at least 1 second while the oil change tripmeter and “OIL” are flashing alternately in the odometer display. The distance traveled since the last oil change and “OIL” will flash alternately in the odometer display.

3. Push the “RESET” button for approximately 3 seconds. “00000” and “OIL” will flash alternately in the odometer display 3 times, and then the display will return to the previous display mode.

If the engine oil is changed before the oil change tripmeter appears in the display (i.e., before the periodic oil change interval has been reached), the tripmeter must be reset after the oil change for the next periodic oil change to be indicated at the correct time. In that case, reset the oil change tripmeter as follows.

Fuel level warning indicator “ ”

The fuel level warning indicator and the warning light come on when the fuel level is low. (See page 18 for details.) The fuel level warning indicator, the warning light, the fuel meter indicator, and all segments of the fuel meter start to flash when a malfunctioning sensor, disconnected coupler, broken lead, or short circuit is detected by the self-diagnosis device of the snowmobile to warn the rider of any of the above problems. If this occurs, have a Yamaha dealer inspect the snowmobile as soon as possible.

2. Warning light “ ”

If the warning indicator and the warning light come on, place the snowmobile on a level surface and allow it to idle for one minute. If the warning indicator and the warning light go off, the engine oil level is sufficient, however it is getting low. Add engine oil as soon as possible. If the warning indicator and the warning light do not go off, check the engine oil level in the oil tank (see page 59 for engine oil level checking procedures), and add engine oil if necessary. If the warning indicator and the warning light still remain on, have a Yamaha dealer check the snowmobile.

Oil pressure warning

The warning indicator comes on and “OPLO” (oil pressure low) appears in the odometer display if the engine oil pressure is low when the engine is started. At the same time, the engine speed is limited to less than the clutch engagement speed until the warning indicator goes off. If the engine oil pressure remains low for one minute, the engine stops. If this occurs, have a Yamaha dealer check the snowmobile.

2. “OP-LO” (oil pressure low)

If there is no engine oil in the oil passages when the engine is started, such as after the engine oil is changed, the warning indicator may come on and “OP-LO” may appear in the odometer display for a few seconds until the oil circulates through the engine. The snowmobile can be operated normally after the warning indicator goes off.
