Operating Instructions

Starting and Stopping
Engine
It is imperative that the brake system be
checked for wear and proper operation
and that all safety checks found in the
accompanying
Handbook be performed before attempt-
ing to start the engine. After the engine
has been started, check the headlights
(high and low beam), taillight, and brake-
light to be sure they are working properly
and adjusted correctly. Make sure all
lights are clean to provide maximum illu-
mination. The headlight and taillight
must be clean and must be illuminated
whenever the engine is running.
1. Test the operation of the brake sys-
tem by compressing the brake lever.
The brake lever must feel firm when
compressed; then while holding the
brake lever in the compressed posi-
tion, measure the distance between
the brake lever and the handlebar.
The distance must be greater than
25.4 mm (1 in.).
2. With the brake fluid reservoir in a
level position
removed, check the fluid level. The
brake fluid level must be at the high
brake fluid mark in the reservoir.
Snowmobile Safety
0745-816B
and the
0745-817
3. If the brake fluid is below the high
brake fluid mark, add Yamaha
approved DOT 4 brake fluid until
the fluid is at the recommended
level. Install and secure the reservoir
cover. Do not allow moisture to con-
taminate the brake system.
Brake fluid is highly corrosive. Do not
spill brake fluid on any surface of the
snowmobile.
! WARNING
Do not overfill the brake fluid reser-
voir. Overfilling the reservoir may
cause the brake system to hydrauli-
cally lock. Use only Yamaha approved
brake fluid.
Do not start the engine if the brake sys-
tem is not functioning properly. Service
the brake system or have it properly
repaired prior to operating the snow-
mobile. Serious personal injury or even
death may occur if the brake system is
not operating properly.
4. Test the throttle control lever by
completely compressing and releas-
ing it several times. The lever
MUST return to the idle position
quickly and completely.
Always check the coolant level before
starting the engine.
5. Make sure the battery is fully
cover
charged to ensure the engine is turn-
ing over at a sufficient RPM to start.

NOTE: Even though the engine
turns over, the engine may not have
sufficient RPM to start.
6. Check the spark plugs and replace as
necessary. Short engine run times
cause carbon buildup on spark
plugs.
7. Ensure the gas tank is full of fresh
gas whenever the snowmobile is
removed from storage.
