Battery
WARNING
z The battery generates flammable gas, so do not bring fire or
sparks near the battery.
z Battery electrolyte is dangerous. If it gets in your eyes or on
your skin, wash it off with a large amount of water and con-
sult a doctor.
z
Battery electrolyte dissolves paint. If it gets on to the body-
work, wash it off immediately with water.
z
If the battery electrolyte is frozen, do not charge the battery
or start the engine with a different power source. There is
danger that the battery may explode.
z
Battery electrolyte is toxic, so do not let it flow into drainage
ditches or spray it on to the ground surface.
When the ambient temperature drops, the capacity of the battery
will also drop. If the battery charge ratio is low, the battery elec-
trolyte may freeze. Maintain the battery charge as close as pos-
sible to 100%, and insulate it against cold temperature so that
the machine can be started easily the next morning.
REMARK
Measure the specific gravity and calculate the rate of charge
from the following conversion table.
z As the battery capacity drops markedly in low temperatures,
cover the battery or remove it from the machine, keep it in a
warm place, and install it again the next morning.
z
If the electrolyte level is low, add distilled water in the morn-
ing before beginning work. Do not add the water after the
day’s work to prevent fluid in the battery from freezing in the
night.
