BBattery Condition
To avoid the possibility of battery explosion:
For the refillable type battery, follow the
instructions below.
A 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.
To avoid personal injury:
A Never remove the vent cap while the engine is
running.
A 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.
A Wear eye protection and rubber gloves when
working around battery.
Mishandling the battery shortens the service life and adds
to maintenance costs.

spring play
