c) Only use accessory parts especially provided for
this tool and recommended by the manufacturer.
The mere fact that you can mount accessory parts
to your power tool does not ensure safe use.
d) The permissible speed of the insertion tool must
be at least as high as the maximum speed speci-
fied on the power tool. Accessories with a higher
speed may break and fly off.
e) The outer diameter and the thickness of the in-
sertion tool must comply with the dimensions
specified on your power tool. lt is not possible to
shield or control insertion tools with different dimen-
sions.
f) Grinding disks, flanges, grinding plates or other
accessory parts must exactly mate the grinding
spindie of your power tool. Insertion tools which
do not exactly mate the grinding spindle of your po-
wertool will perform irregular rotations, cause high
vibrations and thus the loss of control.
g) Do not use damaged insertion tools. Prior to
each application, you must check insertion tools
such as grinding disks for chippings and cracks,
grinding plates for cracks, wear or major abra-
sion, wire brushes for loose or broken wires. lf
the power tool or insertion tool falls down, you
must check it for damages, or use an undama-
ged insertion tool. After you have checked and
inserted the insertion tool, both you and persans
in the vicinity must stay out of the Ievel of the
rotating insertion tool, and the tool must be ope-
rated at maximum speed for one minute. Most
of the damaged insertion tools will break within this
test period.
h) Wear personal protective equipment. Depending
on the application of the power tool, you must
wear a full face shield, eye protection or gogg-
les.lf appropriate, you must wear a dust mask,
hearing protection, protective gloves or a special
apron which protects you against small grinding
chips and material particles. Protect your eyes
against foreign objects which fly off du ring different
operations. The purpose of dust masks and brea-
thing equipment is to filter the dust generated during
the operation. Long-term exposure to high noise pol-
lution may cause hearing loss.
i) Make sure that other persons stay a safe dis-
tance away from your working area. Persons
accessing your working area must wear personal
protective equipment. Fragments of the work piece
or broken insertion tools may fly off and cause injury
even outside the direct working area.
j) Always hold the tool by its insulated handles
when the insertion tool may come into contact
with hidden power lines or with the power cord
of the power tool. Contact with live lines may ener-
gise metaI tool parts and cause electric shock.
k) Keep the power cord away from rotating inser-
tion tools. lf you lose control of the power tool, the
power cord may be cut or trapped, and your hand
or arm may get into the path of the rotating insertion
tool..
l) Never put aside the power tool before the com-
plete halt ofthe insertion tool. Rotating insertion
tools may get in contact with the place of deposit
thus causing the loss of control of the tool.
m)Switch oft the power tool while you carry it
around. Your clothes may be trapped when uninten-
tionally getting in contact with the rotating insertion
tool and the insertion tool may penetrate your body.
n) The ventilationslots of your power tool must be
cleaned on a regular basis. The motor fan sucks in
dust, and the accumulation of metaI dust may cause
electrical risks.

o) Do not use the power tool in the vicinity of in-
flammable materials. Sparks may ignite these ma-
terials.
p) Do not use insertion tools which require liquid
coolants. Using water or other liquid coolants may
cause electric shock.
Further safety notes for all applications - kickback
and corresponding safety notes
A kickback is the sudden reaction caused by rotating
insertion tools such as a grinding disk, grinding plate,
wire brush, etc. which has got caught or which blocks.
Getting caught or blocking results in the immedia-
testop of the rotating insertion tool. This accelerates
the uncontrolled power tool against the rotary direction
of the insertion tool.
lf for example a grinding disk gets caught or blocks
in the work piece, the edge of the grinding disk which
penetrates the work piece may get caught, the grin-
ding disk will make a sudden movement or cause a
kickback. As a result, the grinding disk moves towards
the operator or away from the operator, depending on
the rotary direction ofthe disk when it blocks. This may
also cause the fracture of grinding disks.
Kickbacks are the result of the improper or incorrect
use of power tools. Kickbacks can be avoided when
observing the following precautionary measures.
a) Hold the power tool firmly in your hands and
bring your body and arms in a position which al-
lows you to adequately react to kickback forces.
Always use the additional handle, if available.
This ensures you the utmost control of kickback
forces or reaction torques when starting your power
tool. When taking appropriate precautions, the ope-
rator is in the position to control kickback and reac-
tion forces.
b) Keep your hands away from rotating insertion
tools. The insertion tool may move over your hand
in the event of a kickback.
c) Keep your body away from the area where the
power tool may move in the event of a kickback.
Kickbacks always move the power tool in opposite
direction to the movement of the grinding disk at the
spot where it blocks.
d) Corners, sharp edges, etc. must be processed
with special care. Make sure that the insertion tool
does not bounce back from or get trapped on the
work piece. The rotating insertion tool tends to jam
in corners, at sharp edges or when it bounces back.
This may cause the loss of control or a kickback.
e) Do not use chain rings or toothed saw blades.
These insertion tools frequently cause kickbacks or
the loss of control of your power tool.
Additional safety notes regarding grinding with
sandpaper- Special safety notes regarding grin-
ding with sandpaper
a) Do not use oversized abrasive sheets; always
observe the manufacturer's specifications for
abrasive sheet dimensions. Abrasive sheets pro-
truding the grinding plate may cause injury or result
in the blocking or tearing apart of the abrasive sheet
or in kickbacks.
