CAUTION : Do not use accessories requiring more than the maximum rated capacity for the auxiliary DC jack. This may overload the circuit and cause the fuse to blow. (See pages 8-33–8-34 for the specified amperage.) Do not use an automotive cigarette lighter or other accessory with a plug that gets hot because the jack can be damaged.
ESU00521 Drive guard The drive guard is designed to cover the V-belt clutch and V-belt in case parts break or come loose. WARNING Make sure that the drive guard is tightened securely before operating the snowmobile. Never run the engine with the V-belt or drive guard removed.
ESU00072 P RE-OPERATION CHECKS NOTE: Pre-operation checks should be made each time the snowmobile is used. WARNING The engine and muffler will be very hot after the engine has been run. Avoid touching the engine and muffler while they are still hot with any part of your body or clothing during inspection or repair.
5% of ethanol can be used, although richer jetting may be required to prevent engine dam- age. Consult a Yamaha dealer. Gasohol contain- ing methanol is not recommended. Make sure that snow or ice does not enter the fuel tank when refueling.
ESU04580 Engine oil level The engine oil level should be checked before each use. CAUTION : Do not run the engine with too much or not enough oil in the oil tank. Oil could flow into the air filter case and the engine could be damaged.
CAUTION : When adding the engine oil, be careful not to fill above the “F” level mark on the oil level gauge/dipstick. Make sure that no foreign material enters the engine oil tank. 7. Insert the oil level gauge/dipstick into the oil filler hole, and then tighten it securely.
The T.O.R.S. will operate and the engine should run between 2,800 and 3,000 r/min. WARNING If the engine does not run between 2,800 and 3,000 r/min, stop the engine by turning the main switch to the “OFF” position and consult a Yamaha dealer.
Do not operate the snowmobile if you find any problems in the brake system. You could lose braking ability, which could lead to an accident. Ask a Yamaha dealer to inspect and repair the brake system. CAUTION : Make sure that the brake lever end does not project out over the handlebar end.
Apply the brake for a few minutes. Check to see if any brake fluid leaks out from the brake hose joints or the master cylinder. WARNING If brake fluid leakage is found, ask a Yamaha dealer for immediate repairs. CAUTION : Brake fluid may deteriorate painted surfaces or plas- tic parts.
ESU00097 Drive track Check the drive track for deflection, wear, or damage. Adjust or replace if necessary. (See pages 8-27–8-29 for more details.) WARNING Do not operate the snowmobile if you find damage to the drive track, or if it has been maladjusted. Drive track damage or failure could result in loss of brak- ing ability and snowmobile control, which could cause an accident.
Check the handlebar for excessive free play: 1. Push the handlebar up and down and back and forth. 2. Turn the handlebar slightly to the right and left. If excessive free play is noticed, consult a Yamaha dealer. ESU00378 Lights Check the lights.
ESU04601 Air filter Always check that there is no snow under the air filter element frame. 1. Remove the shroud. (See pages 8-5–8-7 for removal procedures.) 2. Unhook the air filter case cover fasteners. 3. Remove the headlight unit bolts and the two top cover bolts near the headlight unit.
ESU00110 Fittings and fasteners Check the tightness of the fittings and fasteners. Tighten in proper sequence and torque if necessary. ESU00345 Tool kit and recommended equipment It is good practice to carry the tool kit, spare parts, and other necessary equipment with you while riding the snowmobile so that minor repairs can be done if neces- sary.
ESU00112 O PERATION ESU04640 Starting the engine WARNING Be sure to check the “SAFETY INFORMATION” section carefully before starting the engine. Make sure that the parking brake is applied. NOTE: Make sure that the engine stop switch is in the on posi- tion.
CAUTION : After 800 km (500 mi) of operation, the engine oil must be changed and the oil filter cartridge replaced. If any engine trouble should occur during the engine break-in period, immediately have a Yamaha dealer check the snowmobile.

Riding downhill 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.
Hard-packed snow WARNING It can be more difficult to negotiate on Drive track damage or failure could hard-packed snow as both the skis and result in loss of braking ability and drive track do not have as much traction as snowmobile control, which could cause when the snowmobile is operated on fresh an accident.
Studs may catch on an object and pull out of the track, leaving tears and damage around the already weakened area. To minimize possible dam- age, consult your stud manufacturer for installation and stud pattern recommendations. Yamaha does not recommend track studding.
ESU00347 Driving WARNING Be sure to read the “SAFETY INFORMATION” and “Riding your snowmobile” sections carefully before operating the snowmobile. NOTE: Make sure that the engine is warmed up enough before riding. For RX10RT 1. Release the parking brake by moving the parking brake lever to the right.
CAUTION : Do not shift from “FWD” to “REV” or from “REV” to “FWD” while the snowmobile is moving. Otherwise, the drive system could be damaged. NOTE: The reverse buzzer beeps while the shift lever is in reverse. 2. Release the parking brake by moving the parking brake lever to the right.
ESU04650 Transporting When transporting your snowmobile on a trailer or in a truck, observe the following recommendations to help protect it from damage: 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.
(if applicable). WARNING If you are not familiar with maintenance work, have a Yamaha dealer do it for you. PROPER PERIODIC MAINTENANCE OF YOUR SNOWMOBILE IS IMPORTANT IN ORDER TO ENJOY LONG, PLEASURABLE SERVICE. ESPECIALLY IMPORTANT ARE THE MAINTENANCE SERVICES RELATED TO EMISSIONS CONTROL.

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 chang- ing to a different type of spark plug. Specified spark plug:...
Page 61
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.
ESU04830 Adjusting the engine idling speed CAUTION : Be sure to have a Yamaha dealer make this adjustment. Make sure that the throttle lever moves smoothly. 1. Remove the shroud, the left and right side covers, and the top cover. (See pages 8-5–8-7 for removal procedures.)
