Operation 48 ESU13500 Read the Owner ’ s Manual carefully to be- come familiar with al l controls. If there is a control or function you do not understand, ask your Yamaha dealer. W ARNING EWS00201 Failure to familiarize yourself with the con- trols can lead to loss of control, which could cause an accident or injury.
Operation 49 4. Warm up the engine until it runs smooth- ly. 5. Be sure the low coolant temperature indi - cator light has gone out before operation. (See page 18 for detailed information about the indicator li ght.) RST90 1. Apply the parking brake. 2.
Operation 50 5. Warm up the engine, and then close the starter (choke) leve r when the engine runs smoothly. 6. Be sure the low coolant temperature indi - cator light has gone out before operation. (See page 18 for detailed information about the indicator li ght.
Operation 51 Pay particular attent ion to the safety informa - tion on page 6. Please read all w arning and notice label s on your snowmobil e . Also, read the Snowmobil - er ’ s Sa fety Handbook that i s supplied with your snowmobile. Learning to ride y our snowmobile Before you ride, always perform the pre-oper- ation checks listed on page 46.
Operation 52 er speeds or in tighter curves. Lean more as the turn gets s harper or is made at higher speeds. Improper riding techniques such as abrupt throttle changes, excessiv e braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the snow- mobile to tip.
Operation 53 Trav ersing a slop e W ARNING EWS00251 Driving across the face of a slope ( “ si de- hilling ” ) can lead to overturn or loss of control if proper techniques are not used.
Operation 54 track, slide runners, and drive sprockets. Op- eration of the snowmobil e on the following surfaces should be avoid ed at all times: ● Dirt ● Sand ● Rocks ● Gras s ● Bare paveme.
