so the least amount of wheel is exposed
towards the operator.The guard helps to protect
operator from broken wheel fragments and acci-
dental contact with wheel.
c) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
d) Always use undamaged wheel flanges that
are of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel flanges.
e) Do not use worn down wheels from larger
power tools. Wheels intended for larger power
tools are not suitable for the higher speed of a
smaller tool and may burst.
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 possi-
bility 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 spin-
ning 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 kick-
back 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 reenter 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 kick-
back. 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, elec-
trical wiring or objects that can cause kickback.

The machine is provided with a "Quick-Stop"
function. For this reason, the machine is
equipped with a special grinding spindle and a
special Metabo "Quick-Stop" adjusting nut.
WHEN FITTING THE TOOLS, ONLY USE THE
ORIGINAL METABO "QUICK-STOP" ADJUSTING
NUT, WHICH CAN BE RECOGNISED BY THE
LETTERING "METABO QUICK-STOP". No other
clamping elements or threaded tools can be fitted
and are not permitted to avoid hazards and injury,
including damage to the grinding spindle. Only the
accessories named in chapter 12 can be fitted.
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Grinding wheels must be stored and handled with
care in accordance with the manufacturer's
instructions.
Never use parting grinder discs for roughing work!
Do not apply pressure to the side of parting grinder
discs.
The tool must lay flat and be secured against slip-
ping, e.g. using clamps. Large workpieces must be
sufficiently supported.
Do not use accessories with threaded inserts.
For your own protection and for the
protection of your power tool pay atten-
tion to all parts of the text that are
marked with this symbol!
Always wear protective goggles.
During machining, of metals in
particular, conductive dust can
form deposits inside the machine. This can lead to
the transfer of electrical energy onto the machine
housing. This can mean a temporary danger of
electric shocks. This is why it is necessary when
the machine is running to blow compressed air
through the rear ventilation slots of the machine
regularly, frequently and thoroughly. Here, the
machine must be held firmly.
We recommend using a stationary extractor
system and connecting a residual current circuit-
breaker (FI) upstream. When the angle grinder is
shut down via the FI circuit-breaker, it must be
checked and cleaned. See chapter 10 Cleaning for
more information on cleaning the motor.
Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory
diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic
such as oak and beech dust especially in conjunc-
tion with additives for wood conditioning (chro-
