6. Insert key into ignition switch; then
rotate key to the RUN position.
NOTE: Rotate the key to the START
position; then when the engine starts,
release the key.
NOTE: When the engine starts,
allow it to warm up properly. Idle the
engine several minutes until the
engine has reached normal operat-
ing temperature. Do not idle the
engine for excessively long periods
of time.
7. There is a “cold drive-away” function
incorporated within the engine. This
function is active until the engine
reaches operating temperature.
8. Flooding — If the engine does not
start but seems ready to start, engage
the brake lever lock; then compress
the throttle control lever fully and try
to start the engine. When the engine
starts, release the throttle control lever
immediately. After the warm-up,
release the brake lever lock.
9. To shut off the engine, turn the igni-
tion key to the OFF position or push
the emergency stop switch to the
DOWN position.
Braking
The following items are items that the
operator must be familiar with when
operating this snowmobile and its
hydraulic brake system. Important addi-
tional information on the proper mainte-
nance of the brake system is found in the
Maintenance section.
1. Use the brakes wisely. Each time the
brakes are applied in all hydraulic
brake systems (including automotive
applications), heat is transferred to the
brake fluid. The amount of heat trans-
ferred during high speed stops and/or
repetitive use may be high enough to
boil the brake fluid and cause the
brakes to either fade or may cause an
unexpected loss of brakes. If this
occurs, the brake fluid requires a cool-
down period before the brakes will
again function properly.
This cool-down period will vary
depending upon the ambient air tem-
perature and the temperature of the
brake fluid. If loss of brakes has
occurred because of high fluid temper-
atures, do not operate the snowmobile
until the cool-down period has expired
and brake lever firmness has returned.
2. Be sure to maintain the brake fluid at
the proper level and take care not to
get any moisture in the system as
moisture in the brake fluid lowers the
boiling point. If the brake fluid is ever
boiled (by high speed stops or repeti-
tive use) or if moisture is allowed to
enter the system, it must be changed.
Never substitute or mix different types
or grades of brake fluid.
3. Never ride the brake. Even main-
taining minimal pressure on the
brake lever will cause the brake pads
to drag on the disc and may overheat
the brake fluid.
CAUTION
Do not continuously run the starter
for more than 5 seconds at a time.
CAUTION
Always turn the ignition switch key to
the OFF position when the snowmo-
bile is not being used. Leaving the
ignition switch in the ON position will
result in discharging the battery and
possible damage to the battery.
WARNING
Excessive, repetitive use of the
hydraulic brake for high speed
stops will cause overheating of the
brake fluid and premature brake
pad wear which will result in an
unexpected loss of brakes.
WARNING
Use only Yamaha approved DOT 4
brake fluid. Never substitute or mix
different types or grades of brake
fluid. Brake loss can result. Check
brake fluid level and pad wear
before each use. Brake loss can
result in severe injury or even
death.
