NOTE:_ If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt. _
EC000038
CAUTION:_

The oil level warning light and
fuel level warning light should
come on when the start switch
is pushed, and they should go

leased.


If the oil level warning light flick-
ers or remains on after starting,
immediately stop the engine,
and then check the engine oil
level and the vehicle for oil leak-
age. If necessary, add engine
oil, and then check the warning
light again. If the warning light
does not come on when push-
ing the start switch, or if it doesnot go off after starting with suf-
ficient engine oil, have a
Yamaha dealer check the elec-
trical circuit.


If the fuel level warning light re-
mains on after starting, stop the
engine, and then check the fuel
level. If necessary, refuel as
soon as possible, and then
check the warning light again. If
the warning light does not come
on when pushing the start
switch, or if it does not go off af-
ter starting with sufficient fuel,
have a Yamaha dealer check the
electrical circuit.

Battery This motorcycle 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.
EC000101
CAUTION:@ Never attempt to remove the battery
cell seals, as this would permanent-
ly damage the battery. @
EW000116
WARNING
@

Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for
15 minutes and seek prompt
medical attention.


Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.


KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
@To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to
have discharged. Keep in mind that the
battery tends to discharge more quickly
if the motorcycle is equipped with op-
tional electrical accessories.To store the battery
1. If the motorcycle will not be used
for more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.
2. If the battery will be stored for
more than two months, check it at
least once a month and fully
charge it if necessary.
3. Fully charge the battery before
installation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals.

CAUTION:@

Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.


To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is re-
quired. Using a conventional
battery charger will damage the
battery. If you do not have ac-
cess to a sealed-type (MF) bat-
tery charger, have a Yamaha
dealer charge your battery.

MOTORCYCLE CARE AND STORAGE
7-5
76. 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, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
8. Cover the muffler outlets with plas-
tic bags to prevent moisture from
entering them.
9. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place (less
than 0°C or more than 30°C). For
more information on storing the
battery, see page 6-29.
NOTE:@ Make any necessary repairs before
storing the motorcycle. @
