2.15.4 Battery
WARNING
• The battery contains diluted sulfuric acid, which will dissolve clothes and skin.
Should you get battery fluid on your clothes or skin, wash it off immediately with
copious quantities of clean water.
• If you get it in your eyes, rinse them straight away with clean water and
immediately seek the help of a doctor.
• If you accidentally ingest it, drink copious quantities of water and immediately
seek the help of a doctor.
• Always wear safely glasses when handling the battery.
• The battery generates hydrogen gas, so there is a danger of explosions.
Avoid recharging the battery, keep cigarettes and flames away, etc., in poorly
ventilated places when there is a danger of generating sparks.
• The inspection and handling of batteries should be carried out with the engine
turned off and the Starter switch in the position.
• Be careful not to accidentally connect the two battery terminals with tools or
other metallic objects.
• Tangled terminals may generate sparks due to improper connections, resulting
in the danger of explosions. Make sure terminals are connected firmly.
• The battery is for starting the engine and operating electrical equipment on the
machine. Do not use it for any other purpose.
When the temperature decreases, the battery capacity will lower, possibly freezing the
electrolyte.
The battery should be maintained in a good state at all times, with care taken to keep it warm
in preparation for use the next morning.
CAUTION
The power-supply voltage of this machine is 12V.
At low temperature, batteries are less efficient. The level of charge is lowered and batteries
will tend to freeze. Maintain batteries fully charged wherever practicable, and give attention to
heat insulation at night for the next day’s operation.
For the level of charge, check the specific gravity of electrolyte and use the following table of
conversion.
