BATTERY

BATTERY REMOVAL

Remove the front tool box cover.
Disconnect the battery cables .

Remove the bolt and battery bracket.
Remove the battery.
The installation sequence is the reverse of
removal.

BATTERY CHARGING (OPEN CIRCUIT
VOLTAGE) INSPECTION

Remove the battery cover and disconnect
the battery cables.
Measure the voltage between the battery
terminals.
Fully charged : 13.0V_ 13.2V
Undercharged : 12.3V max.

CHARGING METHOD

Connect the charger positive (+) cable to
the battery positive (+) cable.
Connect the charger negative (-) cable to the
battery negative (-) cable.

Charging current : Standard : 0.4A

Quick : 4A

Charging time : Standard : 5 hours

Quick : 0.5 HOUR

After charging: Op en circuit voltage: 12.8V min.

Front tool box Cover

First disconnect the battery negative (-)
cable and then the positive (+) cable.

＊

Battery charging inspection must be
performed with an electric tester.

＊

• Quick charging should only be done in

an emergency.

• During quick charging, the battery

temperature should not exceed
45℃ .

• Measure the voltage 30 minutes after

the battery is charged.

＊

• Keep flames and sparks away

from a charging battery.

• Turn power ON/OFF at the

charger, not at the battery terminals to
prevent sparks near the battery.

• Charge the battery according to

the current specified on the battery
surface.
