OPERATION AND IMPORTANT RIDING POINTS
5 7. When the engine is warm, turn
the starter (choke) off.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.
EAU01258
Starting a warm engineEngine, starting a warmFollow the same procedure as for
starting a cold engine with the excep-
tion that the starter (choke) is not
required when the engine is warm.
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
engine more than 10 seconds on any
one attempt.6. After starting the engine, move
the starter (choke) knob back
halfway.
ECA00055
cCFor maximum engine life, always
warm the engine up before starting
off. Never accelerate hard when
the engine is cold!

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 eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.

EXTERNAL: Flush with plen-
ty of water.

INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.

Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes,
etc., away from the battery and
provide sufficient ventilation
when charging it in an
enclosed space.

6 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 dis-
charge more quickly if the motorcycle
is equipped with optional 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
connected to the battery termi-
nals.
EAU01307
Replacing the fuseFuse, replacingThe fuse holder is located behind
panel A. (See page 6-7 for panel
removal and installation procedures.)
If the fuse is blown, replace it as fol-
lows.
1. Turn the key to “OFF” and turn
off all electrical circuits.
2. Remove the blown fuse, and
then install a new fuse of the
specified amperage.

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
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.

MOTORCYCLE CARE AND STORAGE
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.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
8. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.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 excessively cold or warm
place (less than 0 °C) or more
than 30 °C). For more informa-
tion on storing the battery, see
page 6-32.
NOTE:
Make any necessary repairs before
storing the motorcycle.
