Inspection of charging state (CCU)

Open cushion.
Unclose the top cover of air filter and disconnect the lead of
battery.

Measure the voltage between the battery terminals.

Fully charged: 13.1V
Undercharge

：

12.3V

*Attention

The inspection of charging state should be made by
voltage meter.

Charging

Connecting method:
Connect the positive pole of charger to that of battery.
The negative pole of charge connects to that of battery.

Warning!

•Fire should be strictly prohibited around battery.
•As starting to charge or upon the completion of charge,
the switch of charger should be turned off first in order to
prevent the sparkle of connecting position from explosion
hazard.
•The current time specified on the battery should be the
reference for charging.

*Attention

•If quick charge of battery is abnormal, the battery should
not be used.
•The voltage should be measured every 30 minutes after
charging.
