contact with the skin, eyes or clothing.
c. Wear closed eye protection and protective clothing. Avoid touching the eyes
when working near batteries.
d. If battery acid comes into contact with skin or clothing, wash immediately
with soap and water. If acid comes into contact with the eyes, rinse them
immediately with running cold water for at least 10 minutes and then seek
medical assistance straight away.
e. NEVER smoke near batteries or the machine. Avoid naked flames or sparks
around the battery or machine.
f. Be extremely careful when handling metal tools to ensure they do not fall
onto the battery. This can produce sparks or the battery or another electrical
component can short-circuit, which can lead to an explosion.
g. Metallic objects such as rings, bracelets, necklaces and watches must be
removed from the body before handling the batteries. A battery can generate
a short circuit current which is high enough to weld a ring or similar metallic
object, causing serious burns.
h. Only use the charger to charge conventional lead or LiFe batteries. Always
ensure to select the correct charging mode. The battery charger is not
designed for supplying a further low-voltage network with energy in addition
to the starter battery. Do not use the battery charger to charge dry batteries
that are often used in home applications. These batteries can burst and
cause personal injury and material damage.
i. NEVER charge a frozen battery.
12.PREPARATIONS FOR CHARGING MODE
a. If the battery has to be removed from the vehicle for charging, always
disconnect the earth of the battery first. Ensure that all consumers in the
vehicle are switched off in order to prevent an arc.
b. During charging, ensure that the environment is well ventilated. Any gas
which is produced during the charging process can be blown away by forced
ventilation by using a piece of cardboard or other non-metallic object as a
fan.
c. Clean the poles of the battery. Ensure that corrosion residue does not come
into contact with the eyes.
d. Fill each cells with distilled water until the battery acid reaches the value
defined by the manufacturer. This helps to remove excess gas from the cells.
Do not over-fill the batteries. For batteries without cell caps, follow the
manufacturer's instructions for recharging carefully.
e. Read all of the specific instructions of the battery manufacturer, such as
whether or not to remove the cell caps during charging and the
recommended charging rates, etc.
f. To ensure that the voltage level is set to the correct value for a battery
charger with an output voltage selector switch, determine the battery voltage
by referring to the vehicle owner's manual. If there is no output voltage
