Braking - Yamaha SR1NRJ Original Instructions Manual

8. Ensure drive belt tension and
deflection 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.
CAUTION
Do not continuously run the starter
for more than 10 seconds at a time.
4. A "cold drive-away" function is incor-
porated within the engine. This func-
tion is active until the engine reaches
operating temperature.
CAUTION
It is extremely important that the engine
is properly warmed up before subject-
ing 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.
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
dealer for inspection and service. This
service 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.
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.

NOTE: When the engine is turned
off, wait for the gauge to completely
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 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 tem-
peratures, do not operate the snowmo-
bile until the cool-down period has
expired and brake lever firmness has
returned.
