Periodic maintenance and adjustment

Battery

A poorly maintained battery will cor-
rode and discharge quickly. The elec-
trolyte level, battery lead connections
and breather hose routing should be
checked before each ride and at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
WARNING
 Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
• EYES: Flush with water for 15
minutes and seek prompt
medical attention.
 Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.
 Take care not to spill electrolyte
on the drive chain, as this may
weaken it, shorten chain life and
possibly result in an accident.
 KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
