• 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 battery.

IMPORTANT

• The factory-installed battery is of non-refillable

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

• 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 for new one,

use battery of equal specification in table
below.

are

designed  to  eliminate  the  need  to  add  water.  Yet  the
volume  of  electrolyte  above  plates  may  eventually
become  depleted  due  to  abnormal  conditions  such  as
high heat or improper regulator setting. Use a voltmeter
to check the state of charge. See reference chart below
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 battery charge by placing a metal

object across the posts. Use a voltmeter or
hydrometer.

(2) Clamp

1. To slow charge the battery, connect the battery

positive terminal to the charger positive terminal
and the negative to the negative, then charge for at
least 1 hour at 6.5 amperes.

2. A boost charge is only for emergencies. It will

partially  charge  the  battery  at  a  high  rate  and  in  a
short  time.  When  using  a  boost-charged  battery,  it
is  necessary  to  recharge  the  battery  as  early  as
possible. Failure to do this will shorten the battery's
service life.

3. When the specific gravity of electrolyte is between

1.27 and 1.29 the charging is completed.

Battery for storage

1. When storing the machine for a long period,

remove the battery from machine, adjust the
electrolyte to the proper level and store in a dry
place out of direct sunlight.

2. The battery self-discharges while it is stored.

Recharge it once every 3 months in hot seasons
and once every 6 months in cold seasons.

WARNING

To avoid serious injury or death:

• Be sure to stop the engine and remove the key

before cleaning the air cleaner element.
