COLD WEATHER OPERATION OPERATION

Battery 3
q The battery generates flammable gas. Do not bring fire or sparks near the battery.
q Battery electrolyte is dangerous. If it gets in your eyes or on your skin, wash it off with a large amount
of water and consult a doctor.
q Battery electrolyte dissolves paint. If it gets on the bodywork, wash it off immediately with water.
q 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.
q Battery electrolyte is toxic. 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 electrolyte may freeze. Maintain the battery charge as close as possible to 100%. Insulate it against
cold temperature to ensure the machine can be started easily the next morning.
Measure the specific gravity and calculate the charging rate from the following conversion table.
q The battery's capacity drastically drops at a low ambient temperature. Therefore either cover it with a mois-
ture- free sheet, or remove it from the machine after the day's work, keep in a warm place and install again
next day.
q If the electrolyte level is low, add distilled water in the morning before beginning work. Do not add water after
the day's work to prevent diluted electrolyte in the battery from freezing during the night.
