Engine break-in 

There is never a more important period in the life of

your engine than the first 20 hours of riding. For

this reason, you should read the following material

carefully.

Since the engine is brand new, do not put an ex-

cessive load on it for the first 20 hours. The various

parts in the engine wear and polish themselves to

the correct operating clearances. During this peri-

od, prolonged full-throttle operation or any condi-

tion that might result in engine overheating must be

avoided.

0–10 hours

Avoid prolonged operation above 1/2 throttle. Vary

the speed of the ATV regularly. Do not operate it at

one set throttle position.

10–20 hours

Avoid prolonged operation above 3/4 throttle. Rev

the engine freely, but do not use full throttle at any

time.

20 hours and beyond

The ATV can now be operated normally.

CAUTION:

ECB00220

If any engine trouble should occur during the

engine break-in period, immediately have a

Yamaha dealer check the ATV.

EBU20700

Parking 

When parking the ATV, stop the engine, shift the

drive select lever into the forward position, apply

the parking brake, and then turn the fuel cock to

“OFF”.

POTENTIAL HAZARD

Improper operation in reverse.

WHAT CAN HAPPEN

You could hit an obstacle or even a person

behind you, resulting in serious injury.

HOW TO AVOID THE HAZARD

When you shift into reverse, make sure there

are no people or obstacles behind you.

When it is safe to proceed, go slowly.
