WARNING
Never use a fuse with an amperage rating
other than that specified. Improvising or us-
ing a fuse with the wrong amperage rating
may cause extensive damage to the electri-
cal system, cause the lighting and ignition
systems to malfunction and could possibly
cause a fire.

CHECKING AND CHARGING THE BATTERY

EWA13290
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poi-
sonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
• Wear protective eye gear when handling or
working near batteries.
• Charge batteries in a well-ventilated area.
• Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
• DO NOT SMOKE when charging or han-
dling batteries.
• KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
• Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
• Skin — Wash with water.
• Eyes — Flush with water for 15 minutes and
get immediate medical attention.
INTERNAL
• Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg or
vegetable oil. Get immediate medical atten-
tion.

NOTICE
• This is a VRLA (Valve Regulated Lead Acid)
battery. Never remove the sealing caps be-
cause the balance between cells will not be
maintained and battery performance will
deteriorate.

ELECTRICAL COMPONENTS
• Charging time, charging amperage and
charging voltage for a VRLA (Valve Regu-
lated Lead Acid) battery are different from
those of conventional batteries. The VRLA
(Valve Regulated Lead Acid) battery should
be charged as explained in the charging
method. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charging
the battery.
TIP
Since VRLA (Valve Regulated Lead Acid) bat-
teries are sealed, it is not possible to check the
charge state of the battery by measuring the
specific gravity of the electrolyte. Therefore, the
charge of the battery has to be checked by mea-
suring the voltage at the battery terminals.
1. Remove:
• Battery cover
• Front carrier
• Battery holding bracket
Refer to "GENERAL CHASSIS" on page 4-1.
2. Disconnect:
• Battery leads
(from the battery terminals)

NOTICE
First, disconnect the negative battery lead
"1", and then positive battery lead "2".
3. Remove:
• Battery
4. Check:
