4.4 Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations:
a) Do not "jam" the cut-off wheel or apply
excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibility
of kickback or wheel breakage.
b) Do not position your body in line with and
behind the rotating wheel. When the wheel, at the
point of operation, is moving away from your body,
the possible kickback may propel the spinning
wheel and the power tool directly at you.
c) When wheel is binding or when interrupting
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.
d) Do not restart the cutting operation in the
workpiece. 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.
e) Support panels or any oversized workpiece
to minimize 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.
f) 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.
4.5 Safety Warnings Specific for Sanding
Operations:
a) 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.
4.6 Only for WEV 15-125 Quick HT, WEV 15-
125 Quick Inox, WEV 17-125 Quick Inox
RT: Safety Warnings Specific for
Polishing Operations:
a) Do not allow any loose portion of the
polishing bonnet or its attachment strings to
spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning
attachment strings can entangle your fingers or
snag on the workpiece.
4.7 Safety Warnings Specific for Wire
Brushing Operations:
a) 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.

b) If the use of a guard is recommended for wire
brushing, 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.
4.8 Additional Safety Instructions:
WARNING – Always wear protective
goggles.
WARNING – Always operate with two hands.
Use elastic cushioning layers if they have been
supplied with the grinding media and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Grinding discs must be stored and handled with
care in accordance with the manufacturer's
instructions.
Never use cutting discs for roughing work! Do not
apply pressure to the side of the cutting discs.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be sufficiently supported.
If accessories with threaded inserts are used, the
end of the spindle may not touch the base of the
hole on the grinding tool. Make sure that the thread
in the accessory is long enough to accommodate
the full length of the spindle. The thread in the
accessory must match the thread on the spindle.
See page 4-5 and chapter 14. Technical
Specifications for more information on the spindle
length and thread.
Use of a fixed extractor system is recommended.
Always install an RCD with a max. trip current of 30
mA upstream. If the angle grinder is shut down via
the RCD, it must be checked and cleaned. See
chapter 9. Cleaning.
Damaged, eccentric or vibrating tools must not be
used.
Avoid damage to gas or water pipes, electrical
cables and load-bearing walls (static).
Pull the plug out of the socket before making any
adjustments, converting or servicing the machine.
Metabo S-automatic safety clutch. When the safety
clutch responds, switch off the machine
immediately!
A damaged or cracked additional handle must be
replaced. Never operate a machine with a defective
additional handle.
A damaged or cracked safety guard must be
replaced. Never operate a machine with a defective
safety guard.
Secure small workpieces. For example, clamp in a
vice.
