per. Larger sanding paper extending too far beyond the
sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety warnings specific for wire brushing operations:
Be aware that wire bristles are thrown by the brush
u
even during ordinary operation. Do not overstress the
wires by applying excessive load to the brush The wire
bristles can easily penetrate light clothing and/or skin.
If the use of a guard is specified for wire brushing, do
u
not allow any interference of the wire wheel or brush
with the guard. Wire wheel or brush may expand in dia-
meter due to work load and centrifugal forces.
Additional safety information
Wear safety goggles.
The protective guard must not be used for
cutting. With a suitable adapter, the protective
guard can also be used for cutting.
Hold the power tool firmly with both hands
and make sure you have a stable footing. The
power tool can be more securely guided with
both hands.
Use suitable detectors to determine if there are hid-
u
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.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Release the On/Off switch and set it to the Off posi-
u
tion when the power supply is interrupted, e.g. when
the battery pack is removed. This prevents uncontrolled
restarting.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
Store the application tools inside buildings, in a dry,
u
frost-free room at a uniform temperature.
Remove the application tools before transporting the
u
power tool. This will allow you to avoid damage.
Bonded cutting and grinding discs have an expiration
u
date, after which the discs must no longer be used.
In case of damage and improper use of the battery, va-
u
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.
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.
