Avoid touching the engine and muffler while they are still hot with any part of your body or clothing during inspection or repair.
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. Do not use alcohol deicers or water absorbing additives with oxygenated fuel. The fuel tank should be filled with straight gaso- line as specified.
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 8-23–8-25 for more details.)
