❏
When wheel is binding or when interrupt-
ing a cut for any reason, switch off the
power tool and hold the power tool
motionless until the wheel comes to a
complete 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
action to eliminate the cause of wheel binding.
❏
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut.
The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
❏
Support panels or any oversized work-
piece to minimize the risk of wheel pinch-
ing 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 existing 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 sand-
ing operations
❏
When sanding, do not use excessively
oversized sanding disc paper. Follow
manufacturers recommendations, when
selecting sanding paper.
Larger sanding
paper extending 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 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 brushing, do not allow any interfer-
ence 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 warnings
Wear safety goggles.
❏
Use suitable detectors to determine if util-
ity lines are hidden in the work area or
call the local utility company for assist-
ance.
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 damage or may cause an electric shock.
❏
When working stone, use dust extraction.
The vacuum cleaner must be approved for
the extraction of stone dust.
Using this
equipment reduces dust-related hazards.
❏
Use a cutting guide when cutting stone.
Without sideward guidance, the cutting disc can
jam and cause kickback.
❏
When working with the machine, always
hold it firmly with both hands and provide
for a secure stance.
The power tool is guided
more secure with both hands.
❏
Secure the workpiece.
A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
❏
Do not work materials containing asbes-
tos.
Asbestos is considered carcinogenic.
❏
Take protective measures when dust can
develop during working that is harmful to
one’s health, combustible or explosive.
Example: Some dusts are regarded as carcino-
genic. Wear a dust mask and work with dust/chip
extraction when connectable.
❏
Keep your workplace clean.
Blends of mate-
rials are particularly dangerous. Dust from light
alloys can burn or explode.
❏
Never use the machine with a damaged
cable. Do not touch the damaged cable
and pull the mains plug when the cable is
damaged while working.
Damaged cables
increase the risk of an electric shock.
❏
Use only original Würth accessories.
