MINOR MAINTENANCE TIPS
CAUTION
Keep the +ve and -ve cables firmly conneted to the respective
battery terminals. Failure to do so will result in damage to the
motorcycle electrical system.
WARNING
Always disconnect the negative (-ve) battery cable first and
then the positive ( +ve) cable while removing the battery
connections. If the positive ( +ve) battery cable should contact
terminal with the negative (-ve) cable installed, the resulting
sparks will cause a battery explosion which could result in
serious injury.
Disconnection in the wrong sequence increases the risk of
short-circuits. Always proceed in the correct sequence.
WARNING
Battery terminals and internals contain lead and lead components,
known to cause cancer and birth defects or other reproductive
harm. Always wear approved protective face shield, rubberized
gloves and protective clothing when working with batteries. Keep
batteries and acid out of reach of children.
Charging the connected battery directly at the battery terminals can
damage the vehicle electronics. Always disconnect the battery from
the on-board circuits before recharging it with a charger connected
directly to the battery posts.
NOTE
Usage of frequency for motorcycle is very important for battery to
be in good performance condition. If the motorcycle is being used
very rarely or sparingly and the terminals are not disconnected the
battery is bound to lose its charge and result in a dead battery.
