f) If the battery gets too hot to touch, this may indicate that it

5.2.4 Electrical safety
Before beginning work, check the working area (e.g. using a
metal detector) to ensure that no concealed electric cables or
gas and water pipes are present. External metal parts of the
power tool may become live, for example, when an electric cable
is damaged accidentally. This presents a serious risk of electric
shock.

5.2.5 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Exposure to
dust at a poorly ventilated workplace may result in damage to
the health.

5.2.6 Personal protective equipment

The user and any other persons in the vicinity must wear
suitable eye protection, a hard hat, ear protection, protective
gloves and breathing protection while the tool is in use.

Store the battery in a cool, dry place. Never store the battery
where it is exposed to direct sunlight or sources of heat, e.g. on
