WARNING
EWB02080
Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability,
which could lead to an accident.
After servicing:
Make sure the brakes operate smoothly and
that the free play is correct.
Make sure the brakes do not drag.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.
EBU24473
Adjusting the rear brake lever and
brake pedal free play
The brake lever and brake pedal free play must be
checked and, if necessary, adjusted at the inter-
vals specified in the periodic maintenance and lu-
brication chart.
NOTE:
Always perform this maintenance completely in
the following order whenever adjusting the rear
brake.
Before adjusting the brake lever and brake pedal
free play, check the rear brake shoes for wear.
Adjusting the brake lever free play
The brake lever free play should measure 5.0–8.0
mm (0.20–0.31 in) as shown. If the free play is in-
correct, adjust it as follows.

is incorrect, adjust it as follows.
Turn the brake pedal free play adjusting nut on the

WARNING
EWB02130
Inspect cables frequently and replace if dam-
aged. Corrosion can result when the cable
sheaths become damaged, and cables can
also become frayed or kinked, which could re-
strict the operation of controls and lead to an
accident or injury.

Checking and lubricating the front and
rear brake levers
The operation of the front and rear brake levers
should be checked before each ride, and the lever
pivots should be lubricated if necessary.

Battery
A poorly maintained battery will corrode and dis-
charge quickly. The electrolyte level, battery lead
connections and breather hose routing should be
checked before each ride and at the intervals
specified in the periodic maintenance and lubrica-
tion chart.
To check the electrolyte level
1. Place the ATV on a level surface.
2. Check the electrolyte level in the battery.
NOTE:
The electrolyte should be between the minimum
and maximum level marks.
3. If the electrolyte is at or below the minimum
level mark, add distilled water to raise it to the
maximum level mark.CAUTION:
ECB00590
Use only distilled water, as tap water contains
minerals that are harmful to the battery.WARNING
EWB02160
Battery electrolyte is poisonous and danger-
ous, as it contains sulfuric acid, which can
cause severe burns. Avoid contact with skin,
eyes or clothing. Always shield your eyes
when working near batteries.
Recommended lubricant:
Lithium-soap-based grease
1. Maximum level mark

CAUTION:
ECB00640
To prevent accidental short-circuiting, turn off
the main switch when checking or replacing a
fuse.
2. Remove the blown fuse, and then install a
new fuse of the specified amperage.
WARNING
EWB02171
Always use a fuse of the specified rating, and
never use a substitute object in place of the
proper fuse. An improper fuse or a substitute
object can cause damage to the electrical sys-
tem, which could lead to a fire.
3. Turn the key to “ON” and turn on the electrical
circuits to check if the devices operate.
4. If the fuse immediately blows again, have a
Yamaha dealer check the electrical system.

CLEANING AND STORAGE
EBU25880
Cleaning
Frequent, thorough cleaning of your ATV will not
only enhance its appearance but will improve its
general performance and extend the useful life of
many components.
1. Before cleaning the ATV:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plug and all filler caps
are properly installed.
2. If the engine case is excessively greasy, apply
degreaser with a paint brush. Do not apply de-
greaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden
hose. Use only enough pressure to do the job.
CAUTION:
ECB00710
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical de-
vices. Many expensive repair bills have result-
ed from improper high-pressure detergentapplications such as those available in coin-
operated car washers.
4. Once most of the dirt has been hosed off,
wash all surfaces with warm water and mild,
detergent-type soap. An old toothbrush or bot-
tle brush is handy for hard-to-reach places.
5. Rinse the ATV off immediately with clean wa-
ter and dry all surfaces with a chamois, clean
towel or soft absorbing cloth.
6. Clean the seat with a vinyl upholstery cleaner
to keep the cover pliable and glossy.
7. Automotive type wax may be applied to all
painted and chrome plated surfaces. Avoid
combination cleaner-waxes. Many contain
abrasives which may mar the paint or protec-
tive finish. When finished cleaning, start the
engine and let it idle for several minutes.WARNING
EWB02310
Wet brakes may have reduced stopping ability,
increasing the chance of an accident. Test the
brakes after washing. Apply the brakes several
times at slow speeds to let friction dry out the
