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
This model is equipped with a sealed-
type (MF) battery, which does not
require any maintenance. There is no
need to check the electrolyte or to
add distilled water.

CAUTION:
●Always keep the battery char-
ged. Storing a discharged bat-
tery can cause permanent bat-
tery damage.
●To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed spa-
ce.
●EEP THIS AND ALL BATTERIES
OUT OF THE REACH OF CHIL-
