render exposed metal parts of the power tool "live"
and give the operator an electric shock.
k) Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
I) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may catch the surface and pull
the power tool out of your control.
m) Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
n) Regularly clean the power tool's air vents.
The motor's fan draws dust into the housing.
o) Do not operate the power tool near flam-
mable materials. Sparks could ignite these mate-
rials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.

Kickback and Related Warnings
Kickback is the sudden response to an accessory
pinching or jamming while rotating. Pinching or
jamming causes the rotating accessory to stop
abruptly, which in turn forces the uncontrolled
power tool in the direction against the accessory's
rotation at the point of jamming.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions. It can
be avoided by taking proper precautions as given
below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use the auxiliary
handle for maximum control over kickback or
torque reaction during start-up. The operator
can control torque reactions or kickback forces, if
proper precautions are taken.
b) Never place your hand near the rotating
accessory. The accessory may kickback over your
hand.
c) Do not allow your body to enter the area
where the power tool would move if kickback
occurs. Kickback will propel the power tool in the
opposite direction of the accessory's movement at
the point of jamming.
d) Use special care when working around
corners, sharp edges etc. You must prevent
accessories from bouncing off the power tool
and becoming jammed. A rotating accessory
tends to jam around corners and sharp edges and
also if bouncing occurs, thus causing loss of control
or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades create
frequent kickback and loss of control.

Safety Warnings Specific for Grinding
with Diamond Cup Wheels:
a) Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
b) The safety guard must be securely attached
to the power tool. Always direct the power tool
so that the wheel is not openly exposed to the
operator. The guard helps to protect the operator
from broken fragments, accidental contact with the
wheel and sparks that could ignite clothing.
c) Wheels must be used only for recommended
applications.
d) Always use undamaged wheel flanges that
are the correct size and shape for your selected
accessories. The correct flanges support the
accessories.

Additional Safety Instructions
WARNING – Always wear protective
goggles.
Wear a suitable dust protection mask.
Observe the specifications of the accessory manu-
facturer! Protect the accessories from grease and
physical impact.
Accessories must be stored and handled with care
in accordance with the manufacturer's instructions.
The workpiece must be seated firmly and be
secured against slipping, e.g. using clamps. Large
workpieces must be supported adequately.
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 3 and chapter 14. Technical Specifica-
tions for more information on the spindle length and
thread.
Impurities that manage to enter the
machine may block the switching
mechanism. This is why, when the machine is
running, it is necessary to blow compressed air
through the rear ventilation slots of the machine
regularly, frequently and thoroughly. The machine
must be held firmly in this case.
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 quartz, oak and beech dust, especially in
conjunction with additives for wood conditioning
(chromate, wood preservative).
- For efficient dust collection, use a suitable
Metabo (M-class) vacuum cleaner together
with this power tool.
