• Do not use or charge the refillable type battery

if  the  fluid  level  is  below  the  [LOWER]  (lower
limit  level)  mark.  Otherwise,  the  battery
component  parts  may  prematurely  deteriorate,
which  may  shorten  the  battery's  service  life  or
cause an explosion.

• Check the fluid level regularly and add distilled

water as required so that the fluid level is
between the [UPPER] and [LOWER] levels.

• When the battery is being activated, hydrogen

and  oxygen  gases  in  the  battery  are  extremely
explosive.  Keep  open  sparks  and  flames  away
from  the  battery  at  all  times,  especially  when
charging the battery.

WARNING

To avoid serious injury or death:

• Batteries, battery posts, terminals and related

accessories contain lead, lead compounds and
other chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm. Wash hands after handling.

• Never remove the battery cap while the engine

is running.

• Keep electrolyte away from eyes, hands and

clothes. If you are spattered with electrolyte,
wash it away completely with water immediately
and get medical attention.

• Keep open sparks and flames away from the

battery at all times. Hydrogen gas mixed with
oxygen becomes very explosive.

• Wear eye protection and rubber gloves when

working around the battery.

NOTE :

• The factory-installed battery is a non-refillable

type.
If the battery is weak, charge the battery or
replace it with a new one.

IMPORTANT :

• Mishandling the battery shortens the service life

and adds to maintenance costs.
The original battery is maintenance free, but
needs some servicing.
If the battery is weak, the engine will be difficult
to start and the lights will be dim. It is important
to check the battery periodically.

• When exchanging an old battery with a new

one, use a battery of equal specifications (as
described in the following table).

Regarding non-accessible maintenance-free type
batteries:
Maintenance-free,

non-accessible

batteries

are

designed  to  eliminate  the  need  to  add  water.  Yet  the
volume  of  electrolyte  above  the  plates  may  eventually
become  depleted  due  to  abnormal  conditions  such  as
high  heat  or  improper  regulator  settings.  Use  a
voltmeter to check the state of charge.
(See  the  following  reference  chart  to  determine  if
charging is necessary.)

DANGER

To avoid serious injury or death:

• When the battery is being activated, hydrogen

and  oxygen  gases  in  the  battery  are  extremely
explosive.  Keep  open  sparks  and  flames  away
from  the  battery  at  all  times,  especially  when
charging the battery.

WARNING

To avoid serious injury or death:

• When disconnecting the cable from the battery,

start with the negative terminal first. When
connecting the cable to the battery, start with
the positive terminal first.

• Never check the battery charge by placing a

metal object across the posts.
Use a voltmeter or hydrometer.
