Do not open the battery. There is a risk of short-circuit-
u
ing.
The battery can be damaged by pointed objects such
u
as nails or screwdrivers or by force applied externally.
An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
Only use the battery with products from the manufac-
u
turer. This is the only way in which you can protect the
battery against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.
Do not touch any application tools or adjacent housing
u
components shortly after operation. These can become
very hot during operation and cause burns.
The application tool may jam during drilling. Make
u
sure you have a stable footing and hold the power tool
firmly with both hands. Otherwise you could lose con-
trol of the power tool.
Take care when carrying out demolition work using
u
the chisel. Falling fragments of the demolition material
could injure you or any bystanders.
