wires by applying excessive load to the brush
The wire
bristles can easily penetrate light clothing and/or skin.
u
If the use of a guard is recommended for wire brush-
ing, do not allow any interference of the wire wheel or
brush with the guard.
Wire wheel or brush may expand
in diameter due to work load and centrifugal forces.
Additional Safety Information
Wear safety goggles.
u
Use suitable detectors to determine if there are hid-
den supply lines or contact the local utility company
for assistance.
Contact with electric cables can cause
fire and electric shock. Damaging gas lines can lead to ex-
plosion. Breaking water pipes causes property damage.
u
Do not touch grinding and cutting discs until they have
cooled down.
The discs can become very hot while work-
ing.
u
Release the On/Off switch and set it to the Off posi-
tion when the power supply is interrupted, e.g. when
the battery pack is removed.
This prevents uncontrolled
restarting.
u
Secure the workpiece.
A workpiece clamped with
clamping devices or in a vice is held more secure than by
hand.
u
Do not open the battery.
There is a risk of short-circuit-
ing.
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.
u
In case of damage and improper use of the battery, va-
pours may be emitted. The battery can set alight or ex-
plode.
Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
u
Only use the battery with products from the manufac-
turer.
This is the only way in which you can protect the
battery against dangerous overload.
u
The battery can be damaged by pointed objects such
as nails or screwdrivers or by force applied externally.
An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
