Checking the wheel bearings
The front and rear wheel bearings
must be checked at the intervals spe-
cified in the periodic maintenance and
lubrication chart. If there is play in the
wheel hub or if the wheel does not
turn smoothly, have a Yamaha dealer
check the wheel bearings.

Battery
1. Battery
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the elec-
trolyte or to add distilled water. Howe-
ver, the battery lead connections
need to be checked and, if necessary,
tightened.
EWA10760
Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyeswhen working near batteries.
In case of contact, administer
the following FIRST AID.
• EXTERNAL: Flush with plenty of water.
• INTERNAL: Drink large quan- tities of water or milk and
immediately call a physician.
• EYES: Flush with water for 15 minutes and seek prompt
medical attention.
Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and provi-
de sufficient ventilation when
charging it in an enclosed space.
KEEP THIS AND ALL BATTE-
RIES OUT OF THE REACH OF
CHILDREN.
To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it seems
to have discharged. Keep in mind that
the battery tends to discharge more
quickly if the vehicle is equipped with
optional electrical accessories.WARNING
