a. Install a new fuse of the correct amperage
rating.
b. Push the start switch to verify if the electri-
cal circuit is operational.
c. If the fuse immediately blows again, check
the electrical circuit.
WARNING
EWA13310
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.
4. Install:

CHECKING AND CHARGING THE BATTERY
WARNING
EWA20430
To avoid sparking, burns, fire, and explo-
sion:
• Charge battery only with specified charger.
• Use battery only for specified product – no
other use.
• Do not place near fire or immerse in water.
• Do not use battery if it has been dropped,
subject to impact, or visibly damaged.
• Do not disassemble or modify the battery,
or short across its terminals.
NOTICE
ECA26041
To prevent damage to the battery and battery
malfunction:
• Be sure to charge the battery using only the
specified battery charger. Do not use a
charger designed for lead-acid batteries.
Otherwise, the battery could be damaged,
such as from a long period of excessive
current or voltage exceeding 16 V.
• Avoid excessive current discharge, such
as pressing the starter switch for a long
time. Wait for more than 10 seconds before
attempting to start again. Charge the bat-
tery again as soon as possible. A long state
of discharge below 10 V will damage the
battery.
• Do not use the specified battery charger to
charge a battery other than the lithium-ion
battery. Otherwise, the battery or charger
could be damaged.
• Be careful not to drop the battery or subject
it to strong impacts.
• Avoid charging the battery at high temper-
atures of 65
C (149
F) or more or low tem-
peratures under 0
C (32
F). A control
feature preventing battery charging and
discharging will temporarily intervene. The
battery will discharge at 65
C (149
F) or
more or low temperatures under -10
C (14
F).
• If the battery is charged between 0
C (32
F)and 10
C (50
F), battery charging may
stop halfway without the battery becoming
fully charged even when the specified bat-
tery charger is used. If this occurs, discon-
nect the battery charger, and then resume
charging again.
TIP
This model uses a lithium-ion battery. When
new, the battery is supplied in sleep mode to
minimize current discharging until first-time use.
In the sleep mode, a voltage as low as approxi-
mately 0.1 V can be measured if voltage mea-
surement is performed. As such the battery
cannot be used, but this is not a malfunction. By
activating the battery as follows, the sleep mode
will be canceled and the battery can be used
normally.
Charging (activation) steps
1. Remove:
•
Side cover (left/right)
•
Seat
Refer to “GENERAL CHASSIS” on page 4-1.
2. Disconnect:
•
Battery lead
(from the battery terminals)
NOTICE
ECA13700
First, disconnect the negative battery lead,
and then the positive battery lead.
3. Remove:
•
Battery
4. Connect the battery charger (special tool) to
the battery.
