MAINTENANCE
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).

5.1 Non accessible maintenance free type
batteries
Maintenance-free, non-accessible
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.

5.2 Checking the battery voltage

Use LCD monitor or a voltmeter to check the state of
charge.
(See the following reference chart to determine if
charging is necessary.)

5.3 How to read indicator

Check the battery condition by reading the indicator.
Specific gravity of electrolyte and quality of elec-
Green
trolyte are both in good condition.
Black Battery needs charging.
White Battery needs replacing.
NOTE :
• When viewing the indicator, check from directly
above by removing the air cleaner cover or
using a mirror.

5.4 Charging the battery

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
are
the positive terminal first.
• Never check the battery charge by placing a
metal object across the posts.
Use a voltmeter or hydrometer.
IMPORTANT :
• Make sure that the wire harness is in the cover.
