Battery A poorly maintained battery will cor-
rode and discharge quickly. The elec-
trolyte level, battery lead connections
and breather hose routing should be
checked before each ride and at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
To check the electrolyte level
1. Remove panel A. (See page 6-4
for panel removal and installation
procedures.)2. Unhook the battery band, and then
disconnect the negative battery
lead from the battery.
3. Pull the battery breather hose out
as shown.
4. Pull the battery out of the battery
compartment.

6 5. Place the battery on a level sur-
face, and then check the electro-
lyte level in the battery.
NOTE:_ The electrolyte should be between the
minimum and maximum level marks. _6. If the electrolyte is at or below the
minimum level mark, add distilled
water to raise the electrolyte to the
maximum level mark.

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.

EC000100
CAUTION:_ Use only distilled water, as tap water
contains minerals that are harmful
to the battery. _7. Check and, if necessary, tighten
the positive battery lead to the
positive battery terminal.
8. Place the battery in the battery
compartment.
9. Connect and tighten the negative
battery lead to the negative battery
terminal.

610. Place the breather hose into the
original position and make sure
that it is properly routed.

12. Install the panel.
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 the
specific gravity of the electrolyte at
least once a month and fully
charge the battery whenever nec-
essary.
3. Fully charge the battery before in-
stallation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals and
that the breather hose is properly
routed, in good condition, and not
obstructed.
EC000099
CAUTION:_ If the breather hose is positioned in
such a way that the frame is ex-
posed to electrolyte or gas expelled
from the battery, the frame could
suffer structural and external dam-
ages. _
