plete stop. Never attempt to remove the cut-off wheel
from the cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective ac-
tion to eliminate the cause of wheel binding.
Do not restart the cutting operation in the workpiece.
u
Let the wheel reach full speed and carefully re-enter
the cut. The wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
Support panels or any oversized workpiece to minim-
u
ize the risk of wheel pinching and kickback. Large
workpieces tend to sag under their own weight. Supports
must be placed under the workpiece near the line of cut
and near the edge of the workpiece on both sides of the
wheel.
Use extra caution when making a "pocket cut" into ex-
u
isting walls or other blind areas. The protruding wheel
may cut gas or water pipes, electrical wiring or objects
that can cause kickback.
Safety Warnings specific for Sanding operations
Do not use excessively oversized sanding disc paper.
u
Follow manufacturers recommendations, when select-
ing sanding paper. Larger sanding paper extending bey-
ond 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 recommended for wire brush-
u
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.
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.
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.
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.
