h.) Wear protective equipment. Depending on the
application, use full face protection, eye pro-
tection or protective goggles. If appropriate,
wear a dust mask, hearing protection, pro-
tective gloves or a special apron capable of
stopping small abrasive and material parti-
cles. The eyes are to be protected from flying
debris generated during various operations.
Dust masks or respirators must filter the dust
generated during the operation. If you are
exposed to loud noise for a long time, you may
suffer hearing loss.
i.) Keep other people at a safe distance away
from your work area. Anyone who enters the
working area must wear personal protective
equipment. Fragments of the work piece or bro-
ken bits and cutters can fly away and cause
injuries even beyond the immediate area of
work.
j.) Hold the device only by its insulated grip sur-
faces if you perform work where the bits and
cutters could contact hidden power cables or
your own mains cable. Contact with a live cable
can energize metal device parts and cause elec-
tric shock.
k.) Keep the mains cable away from rotating bits
and cutters. If you lose control of the device,
the mains cable could be cut or snagged, and
your hand or your arm could get pulled into the
rotating bits and cutters.
l.) Never set down the power tool until the bits
and cutters come to a complete stop. Turning
bits and cutters grab the depositing surface and
pull the power tool out of your control.
m.) Do not allow the power tool to run while you
are carrying it. Your clothing could get snagged
accidentally in the rotating bits and cutters,
causing the power tool to pierce your body.
n.) Regularly clean the ventilation slits of your
power tool. The motor fan sucks dust into the
housing and a strong accumulation of metal
dust can cause electrical hazards.
o.) Do not use the power tool in the vicinity of
combustible materials. Sparks could ignite
these materials.

p.) Do not use bits and cutters that require liquid
coolants. The use of water or other liquid
coolants can cause electric shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, sanding band, brush or any
other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the accessory's rotation.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the sur-
face of the material causing the wheel to climb out
or kick out. The wheel may either jump toward or
away from the operator, depending on direction of
the wheel's movement at the point of pinching.
Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and
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. The operator can con-
trol kickback forces, if proper precautions are
taken.
b)
Use special care when working corners,
sharp edges etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
accessory and cause loss of control or kick-
back.
c)
Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
d)
Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direc-
tion as the chips are thrown). Feeding the tool
in the wrong direction causes the cutting edge
of the bit to climb out of the work and pull the
tool in the direction of this feed.
