tear, wire brushes for loose or broken wi-
res. If the power tool or bits and cutters
are dropped, check for damage or install
undamaged bits and cutters. After you have
inspected and installed the bits and cutters,
keep yourself and any other persons in the
vicinity away from the plane of the rota-
ting bits and cutters and run the device at
maximum rotational speed for one minute.
Damaged bits and cutters usually break during
this test time.
h. Wear protective equipment. Depending on
the application, use full face protection, eye
protection or protective goggles. If approp-
riate, wear a dust mask, hearing protection,
protective gloves or a special apron capab-
le of stopping small abrasive and material
particles. The eyes are to be protected from
fl ying debris generated during various opera-
tions. Dust masks or respirators must fi lter 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 pro-
tective equipment. Fragments of the work
piece or broken bits and cutters can fl y away
and cause injuries even beyond the immediate
area of work.
j. Hold the device only by its insulated grip
surfaces 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 electric shock.
k. Keep the mains cable away from rotating
bits and cutters. If you lose control of the de-
vice, 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 li-
quid 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 surface 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 move-
ment at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse and/
or incorrect operating procedures or conditions
and can be avoided by taking proper precau-
tions as given below.
a. Maintain a fi rm grip on the power tool and
position your body and arm to allow you to
