BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is
not necessary to check the elec-
trolyte or fill the battery with distilled
water.
8 8
If the battery seems to have dis-
charged, consult a Yamaha deal-
er.
8 8
If the motorcycle is equipped
with optional electrical acces-
sories, the battery tends to dis-
charge more quickly, so be sure
to recharge it periodically.
EC000101
cCNever try to remove the sealing
caps of the battery cells. The bat-
tery will be damaged.
Battery storage
When the motorcycle is not used for
a month or longer, remove the bat-
tery, fully charge it and store it in a
cool, dry place.
EC000102
cC8
8
Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.
8 8
Use a battery charger
designed for a sealed-type
(MF) battery. Using a conven-
tional battery charger will
cause battery damage. If you
do not have a sealed-type bat-
tery charger, contact your
Yamaha dealer.
8 8
Always make sure the connec-
tions are correct when rein-
stalling the battery.
EW000116
wBattery electrolyte is poisonous
and dangerous, causing severe
burns, etc. It contains sulfuric
acid. Avoid contact with skin, eyes
or clothing.
ANTIDOTE:
8 8
EXTERNAL: Flush with water.
8 8
INTERNAL: Drink large quanti-
ties of water or milk. Follow
with milk of magnesia, beaten
egg, or vegetable oil. Call a
physician immediately.
8 8
EYES: Flush with water for 15
minutes and get prompt med-
ical attention.
Batteries produce explosive
gases. Keep sparks, flame, ciga-
rettes etc., away. Ventilate when
charging or using in an enclosed
space. Always shield your eyes
when working near batteries.
KEEP OUT OF REACH OF CHIL-
DREN.

6.Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7.Check and, if necessary, correct
the tire air pressure, then raise
the motorcycle so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
8.Cover up the muffler outlet with a
plastic bag to prevent moisture
from entering.9.Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the battery
in an excessively cold or warm
place (less than 0¡C or more
than 30¡C). For more informa-
tion, see
ÒBattery storageÓ in the
chapter ÒPERIODIC MAINTE-
NANCE AND MINOR
REPAIRSÓ.
NOTE:
Make any necessary repairs before
storing the motorcycle.
