back may propel the spinning wheel and the power tool
directly at you.
When wheel is binding or when interrupting a cut for
u
any reason, switch off the power tool and hold the
power tool motionless until the wheel comes to a com-
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 utility lines are
u
hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
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 position
u
when the power supply is interrupted, e. g., in case of
1 609 92A 5C5 | (06.07.2020)
a power failure or when the mains plug is pulled. 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.
