BATTERY
To avoid personal injury:
A
Be careful not to let the battery
electrolyte contact your body or
clothing.
A Wear eye protection and rubber
gloves, since the diluted sulfuric acid
solution burns skin and eats holes in
clothing. Should this occur,
immediately wash it off with running
water and get medical attention.
Mishandling of the battery shortens the service life and
adds to maintenance costs. Obtain the maximum
performance and the longest life of the battery by
handling properly and with care.
Engine starting will be more difficult, if the battery charge
is low. Be careful to recharge it at an early occasion
before it is too late.
B
Battery charging
The battery comes in two types:
refillable and non-refillable.
A
For using the refillable type battery,
follow the instructions below.
Do not use or charge the battery if its
fluid level stands below the LOWER
(lower limit level) mark.
Otherwise, the battery component
parts may deteriorate earlier than
expected, which may shorten the
battery's service life or cause an
explosion.
Immediately, add distilled water until
the battery's fluid level is between
the UPPER and LOWER levels.
To avoid personal injury:
A 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.
A
When charging the battery, remove
the battery vent plugs.
A
When disconnecting the cable from
the battery, start with the negative
terminal, and when connecting them,
start with the positive terminal first.
A DO NOT check the battery charge by
placing a metal object across the
terminals. Use a voltmeter or
hydrometer.
1. Make sure each electrolyte level is to the bottom of
vent wells, if necessary, add only distilled water in a
well-ventilated place.
2. To slow charge the battery, connect the charger
positive terminal to the battery positive terminal, and
negative to the negative.
3. Quick recharging charges the battery at a high rate in
a short time. As this is only for emergencies.
4. Recharge the battery as early as possible, or battery
life will be extremely shortened.
5. When exchanging an old battery into new one, use
battery of equal specification shown in page 26 .
