8. Ensure drive belt tension and deflec-
tion are correct to reduce starter drag.
Starting and Stopping Engine
1. Move the emergency stop switch to
the UP or RUN position.
2. Insert key into ignition switch; then
rotate key to the RUN position.
NOTE: When a cold engine is
being started, DO NOT COMPRESS
THE THROTTLE CONTROL LEVER.
If the throttle control lever is com-
pressed, the engine will not start
because the fuel/air mixture will be
too lean.
3. Rotate the key to the START posi-
tion for 5-10 seconds; then when the
engine starts, release the key.
4. A “cold drive-away” function is
incorporated within the engine. This
function is active until the engine
reaches operating temperature.
5. 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.
NOTE: Spark plugs can be
changed by the snowmobile owner
if qualified to do so. If the owner
does not feel qualified, take the
snowmobile to an authorized
YAMAHA Snowmobile dealer for
inspection and service. This ser-
vice is at the discretion and
expense of the snowmobile owner.
6. To shut off the engine, turn the igni-
tion key to the OFF position or push
the emergency stop switch to the
DOWN position.
NOTE: When the engine is turned
off, wait for the gauge to com-
pletely power down before
attempting to start the engine.
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
transferred 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.
CAUTION
Do not continuously run the starter
for more than 10 seconds at a time.
CAUTION
It is extremely important that the
engine is properly warmed up
before subjecting the engine to high
speed operation or heavy loads.
The engine should be allowed to
idle at least 3-4 minutes before it is
operated at more than 1/2 throttle.
In extremely cold conditions, the
warm-up time will be longer. Cold
seizure and piston scuffing caused
by insufficient warm-up will not be
covered by warranty. Also, do not
idle the engine for excessively long
periods of time.
CAUTION
Always turn the ignition switch key
to the OFF position when the snow-
mobile is not being used. Leaving
the ignition switch in the ON position
will result in discharging the battery
and possible damage to the battery.
