Safety instructions for all applications
Special safety instructions for grinding and
cut-off grinding
a) This power tool is to be used as a grinder and cut-
off grinder. Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed be-
low may result in electric shock, fire and/or serious in-
jury.
b) Operations such as sandpaper grinding, wire
brushing or polishing are not recommended to be
performed with this power tool. Operations for
which the power tool was not designed may create a
hazard and cause personal injury.
c) Do not use any accessories that have not been
specifically provided or recommended by the
manufacturer for this power tool. Just because you
can attach the accessories to your power tool does
not guarantee they are safe to use.
d) The maximum speed of the accessory tool used
must be at least as high as the maximum speed
specified for the power tool. Accessories which ro-
tate faster than the maximum permissible rate can
break and throw pieces into the air.
e) The external diameter and thickness of the acces-
sory tool used must comply with the dimensions
of the power tool. Incorrectly dimensioned accessory
tools cannot be sufficiently shielded or controlled.
f) Attachment tools with a thread insert must match
the thread of the grinding spindle exactly. For at-
tachment tools that are mounted using a flange,
the diameter of the hole on the attachment tool
must correspond to the width of the fitting on the
flange. Accessory tools that cannot be firmly fitted to
the power tool rotate unevenly, vibrate severely and
can lead to a loss of control.
g) Never use damaged accessory tools. Before each
use, check tools such as grinding discs for chip-
ping and cracks, grinding wheels for cracks, wear
or heavy wear. If the power tool or the accessory
tool in use is dropped, check to see if it is dam-
aged or use an undamaged accessory tool. Once
you have checked and used the tool attachment,
ensure that you and all other persons in the vicini-
ty remain outside the plane of the rotating tool at-
tachment and allow the device to run for 1 min. at
the maximum speed. Damaged accessories usually
break during the test period.
h) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. Where appropriate, wear a dust
mask, hearing protection, protective gloves or a
special apron that will keep small grinding and
material particles away from you. The eye protec-
tion must be capable of stopping flying debris generat-
ed by various operations. Dust or breathing masks
must filter the dust generated during use. Prolonged
exposure to high intensity noise may cause hearing
loss.
i)
Ensure that other people remain at a safe distance
from your workspace. Anyone who enters the
workspace must wear personal protective equip-

ment. Fragments of the workpiece or broken accesso-
ry tools can fly off and cause injury – even outside the
immediate working area.
j)
Hold the power tool by the insulated handles
when you are carrying out work in which the ac-
cessory tool may come into contact with con-
cealed power cables. Contact with a live wire may
make exposed metal parts of the power tool live and
could give the operator an electric shock.
k) Keep the power cord away from any rotating ac-
cessories. If you lose control of the device, the mains
cable can be severed or caught and your hand or arm
pulled into the rotating insert tool.
l)
Never put the power tool down until the accessory
tool being used has come to a complete standstill.
The rotating accessory tool can come into contact with
the surface and cause you to lose control of the power
tool.
m) Do not run the power tool while carrying it at your
side. Accidental contact of your clothing with the rotat-
ing attachment part could lead to an injury.
n) Clean the ventilation slits of your power tool regu-
larly. The engine fan draws dust into the housing and
a strong accumulation of metal dust can cause electri-
cal hazards.
o) Never use the power tool in the vicinity of inflamma-
ble materials. Sparks can ignite such materials.
p) Do not use any accessory tools which require liq-
uid coolant. The use of water or other liquid coolants
may lead to an electric shock.
Kick-back and corresponding safety
instructions
Kick-back is the sudden reaction resulting from a caught
or jammed rotating insert tool, such as a grinding disc,
grinding wheel, etc. Catching or jamming results in the ro-
tating insert tool stopping abruptly. As a result, an uncon-
trolled electric tool is accelerated against the direction of
rotation of the tool attachment at the blocking point.
For example, if a grinding disc catches or jams in the
workpiece, the edge of the grinding disc that plunges into
the workpiece can get caught, causing the grinding disc to
break away or kick back. The grinding disc may either
jump toward or away from the operator, depending on di-
rection of the wheel's movement at the point of pinching.
Abrasive wheels may also break under these conditions.
Kickback is the result of incorrect or deficient use of the
power tool. It can be prevented by suitable precautionary
measures, as described in the following.
a) Hold the power tool firmly in both hands and posi-
tion your body and arms so they can absorb the
force of a kickback. Always use the additional
handle, if available, so that you have the maximum
possible control over the kickback force or reac-
tion forces at full speed. By taking adequate precau-
tions, the operator can stay in control of the kickback
and reaction forces.
b) Never hold your hand close to a rotating accesso-
ry tool. The accessory tool could jump out of your
hand if there is a kickback.
