SERVICING
Visually inspect the surface of the battery container. If any signs
of cracking or electrolyte leakage from the sides of the battery
have occurred, replace the battery with a new one. If the battery
terminals are found to be coated with rust or an acidic white
powdery substance, clean the battery terminals with sandpaper.
RECHARGING OPERATION
• Using the multi circuit tester, check the battery voltage. If the
voltage reading is less than the 12.0 V (DC), recharge the bat-
tery with a battery charger.

Recharging time: 5 A for 1 hour or 1.2 A for 5 to 10 hours

• After recharging, wait for more than 30 minutes and check the
battery voltage with a multi circuit tester.
• If the battery voltage is less than the 12.5 V, recharge the bat-
tery again.
• If battery voltage is still less than 12.5 V, after recharging,
replace the battery with a new one.
• When the motorcycle is not used for a long period, check the
battery every 1 month to prevent the battery discharge.
* When recharging the battery, remove the battery
from the motorcycle.
