Open the battery cover and remove the battery by removing the bolt and band. First disconnect the battery negative (-) cable and then the positive (+) cable. When disconnecting the battery positive (+) cable, do not touch the frame with tool; otherwise it will cause short circuit and sparks to fire the fuel. The installation sequence is the reverse of removal. First connect the positive (+) cable and then negative (-) cable to avoid short circuit. BATTERY VOLTAGE (OPEN CIRCUIT VOLTAGE) INSPECTION Remove the floor board. Open the battery cover and disconnect the battery cables. Measure the voltage between the battery terminals. Fully charged : 13.1V Undercharged : 12.3V max. Battery charging inspection must be performed with a voltmeter. CHARGING Connect the charger positive (+) cable to the battery positive (+) terminal. Connect the charger negative (-) cable to the battery negative (-) terminal. · 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 to avoid explosion. · Charge the battery according to the ifi d h b · Quick charging should only be done in an emergency. · Measure the voltage 30 minutes after the battery is charged. Charging current : Standard : 0.9A Quick : 3.0A Charging time : Standard : 510 hours Quick : 30 minutes After charging: Open circuit voltage: 12.8V min. 14-4
