U8FU10.book Page 2 Thursday, April 8, 2004 6:27 PM ESU00380 Break-in There is never a more important period in the life of your engine than the period between 0 and 500 km (300 mi). For this reason, you should read the following material carefully. Since the engine is brand new, do not put an excessive load on it for the first 500 km (300 mi). The various parts in the engine wear and polish themselves to the correct operating clearances.
U8FU10.book Page 3 Thursday, April 8, 2004 6:27 PM totally familiar with the snowmobile’s handling and performance characteristics. ESU01272 Riding your snowmobile Getting to know 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. A snowmobile is a rider active vehicle, and your riding position and your balance are the two basic factors of maneuvering your snowmobile.
U8FU10.book Page 4 Thursday, April 8, 2004 6:27 PM Turning 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.
U8FU10.book Page 5 Thursday, April 8, 2004 6:27 PM 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. If this happens, steer in the direction of the slide if there are no obstacles in your path.
U8FU10.book Page 6 Thursday, April 8, 2004 6:27 PM Hard-packed snow WARNING 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. @ Drive track damage or failure could result in loss of braking ability and snowmobile control, which could cause an accident.
U8FU10.book Page 7 Thursday, April 8, 2004 6:27 PM 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 8-29–8-31 for adjustment procedures.) A loose track can slip (ratchet), derail or catch on suspension parts causing severe damage.
U8FU10.book Page 8 Thursday, April 8, 2004 6:27 PM ESU00245 Strap For RX10M/RX10MS The strap 1 should be used only by experienced operators to assist them when traverse (side-hill) riding. WARNING @ Improper use of the strap on the handlebar can result in severe injury or death. ● Use the strap only as an operator grip point when needed to shift weight uphill to maintain balance during traverse (side-hill) riding. Only experienced operators should traverse slopes steep enough to require strap use.
U8FU10.book Page 9 Thursday, April 8, 2004 6:27 PM 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 RX10/RX10M/RX10MS 1. Release the parking brake by moving the parking brake lever to the right. 2. Press the throttle lever slowly to move the snowmobile. 3. Turn the handlebar in the desired direction. 4.
U8FU10.book Page 10 Thursday, April 8, 2004 6:27 PM 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. 3. Press the throttle lever slowly to move the snowmobile. 4. Turn the handlebar in the desired direction. 5. Squeeze the brake lever to stop the snowmobile.
U8FU10.book Page 11 Thursday, April 8, 2004 6:27 PM ESU00367 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 cylinders.

U8FU10.book Page 4 Thursday, April 8, 2004 6:27 PM ESU00376 Tool kit The owner’s tool kit has the tools which are sufficient for most periodic maintenance and minor repair. A torque wrench is also necessary to properly tighten nuts and bolts. 1 Tool kit CAUTION: @ Before starting the engine, make sure that the tool kit is firmly seated in the holder and is closed securely.
U8FU10.book Page 5 Thursday, April 8, 2004 6:27 PM 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.

Turn the throttle stop screw 1 in or out to adjust the engine idle speed.
U8FU10.book Page 7 Thursday, April 8, 2004 6:27 PM ESU00369 Carburetor adjustment CAUTION: @ ● ● Be sure to have a Yamaha dealer make this adjustment. Make sure that the air filter case is installed during running to prevent engine damage. @ Under some operating conditions the carburetor setting may have to be changed due to air temperature changes, elevation changes, use of alcohol oxygenated fuels, etc., and should be set by a Yamaha dealer.

U8FU10.book Page 10 Thursday, April 8, 2004 6:27 PM ESU00157 High altitude adjustments 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.
U8FU10.book Page 11 Thursday, April 8, 2004 6:27 PM ESU03492 Changing the engine oil It is recommended to have a Yamaha dealer change the engine oil. WARNING @ Engine oil is extremely hot immediately after the engine is turned off. Coming into contact with or getting any engine oil on your clothes could result in burns. @ CAUTION: @ ● ● ● Do not run the engine with too much or not enough oil in the oil tank. Oil could spray out or the engine could be damaged.
