ESU00011 2- 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. [. . . ] 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. @ 7-10 ESU00367 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 cylinders. 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 takes longer than 30 minutes. G 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. G 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 another protectant. This will help protect against corrosion. 1 Tool kit CAUTION: @ Before starting the engine, make sure that the tool kit is firmly seated in the holder and is closed securely. @ NOTE: @ If you do not have a torque wrench available during a service operation requiring one, take your snowmobile to a Yamaha dealer to check the torque settings and adjust them if necessary. @ ESU00368 Spark plug inspection 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. Specified spark plug: · R · CR9E (NGK) or CR9E (NGK) 8-4 Spark plugs are produced in several different thread lengths. [. . . ] G Do not use harsh chemicals or cleaning compounds. G Do not polish the matte black finish as the surface could become shiny. G If the matte black finish is in need of repair or touch-ups, contact a Yamaha dealer. @ 10-1 6. Battery Remove the battery from the snowmobile. [. . . ]
