Yamaha SR10LE, Operator'S Manual

14



NOTE:  When  the  engine  starts,

allow it to warm up properly. Idle the

engine  several  minutes  until  the

engine has reached normal operating

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.

4. The brake lever lock is not a parking

brake and should not be applied for

periods exceeding 5 minutes.

NEVER OPERATE THE SNOW-

MOBILE WITH THE BRAKE

LEVER LOCK ENGAGED.

CAUTION

Always  turn  the  ignition  switch  key  to

the OFF position when the snowmobile

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.
