erating lamp is not lit. Turn the battery disconnect switch to OFF position, and remove the key.
Cleaning the battery

Danger of battery exploding
When the battery is being charged, flammable hydrogen gas is generated. Battery may explode. In addition, the
battery electrolyte includes dilute sulphuric acid. Any mistake in handling may cause serious personal injury, ex-
plosion, or fire, so always observe the following.
•
Do not use or charge the battery if the battery electrolyte is below LOWER LEVEL mark. This may cause
an explosion. Always perform periodic inspection of the battery electrolyte level, and add the purified water
(such as a commercial battery fluid) to UPPER LEVEL mark.
•
Do not use a dry cloth when cleaning the battery. Use a wet cloth to prevent a fire or explosion caused by
the static electricity.
•
Do not smoke or bring any open flame close to the battery.
•
Hydrogen gas is generated when the battery is being
charged, so remove the battery from the machine, take it
to a well-ventilated place, remove the battery caps, then
perform the charging.
•
After charging, tighten the battery caps securely.
