Battery
A DANGER
To avoid the possibility of battery explosion:
For the refillable type battery, follow the
instructions below.
• 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.
A CAUTION
To avoid personal injury:
• Never remove the vent caps while the engine is
running.
• Keep electrolyte away from eyes, hands and
clothes. If you are spattered with it, wash it
away completely with water immediately and
get medical attention.
• Wear eye protection and rubber gloves when
working around the battery.
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.
