ESU00011 INTRODUCTION Congratulations on your purchase of a Yamaha snowmobile. This model is the result of Yamaha's vast experience in the production of fine sporting and touring snowmobiles. It represents the high degree of craftsmanship and reliability that have made Yamaha a leader in these fields. [. . . ] Avoid rapid acceleration, turning, and braking. @ WARNING Drive track damage or failure could result in loss of braking ability and snowmobile control, which could cause an accident. G Always check the drive track for damage or maladjustment before operating the snowmobile. G Do not operate the snowmobile if you find damage to the drive track. @ 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. Bare pavement Other surfaces that should be avoided for the sake of drive track and slide runner life are: 1. 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. CAUTION: @ Ride on fresh snow frequently. Operating on ice or hard-packed snow will rapidly wear the slide runners. @ 7-6 ESU02510 Maximizing drive track life Recommendations Track tension During initial break-in, the new drive track will tend to stretch quickly as the track settles. Press the throttle lever slowly to move the snowmobile. Turn the handlebar in the desired direction. Squeeze the brake lever to stop the snowmobile. 7-8 6. Apply the parking brake -- squeeze the brake lever, push and hold the parking brake button down, and then release the brake lever. ESU01360 Stopping the engine Turn the main switch to the "OFF" position to stop the engine. 1 "OFF" WARNING @ G G Push down the engine stop switch to stop the engine in an emergency. Make sure that the key is removed from the main switch whenever the operator leaves the snowmobile, to prevent accidental starting. @ 7-9 ESU01380 Transporting When transporting your snowmobile on a trailer or in a truck, observe the following recommendations to help protect it from damage: G 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. G If transporting the snowmobile in an open trailer or truck, put a tight fitting cover on the snowmobile. [. . . ] 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 equiva- lent fogging oil, to protect both the combustion 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. Moisture and acids form during combustion which can actually increase the chance for corrosion damage during the storage period. @ 5. [. . . ]
