4. Special Safety Instructions
4.1
Safety warnings common for grinding,
sanding, wire brushing, polishing,
carving or abrasive cutting-off
operations:
a) This power tool is intended to function as
a grinder and sander, wire brush, polisher,
carving or cut-off tool. Read all safety
warnings, instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury.
ENGLISH en
b) Do not use accessories which are not
specifically designed and recommended
by the tool manufacturer. Just because the
accessory can be attached to your power tool, it
does not assure safe operation.
c) The rated speed of the grinding accessories
must be at least equal to the maximum speed
marked on the power tool. Grinding accessories
running faster than their rated speed can break
and fly apart.
d) The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately controlled.
e) The arbour size of wheels, sanding drums
or any other accessory must properly fit the
spindle or collet of the power tool. Accessories
that do not match the mounting hardware of
the power tool will run out of balance, vibrate
excessively and may cause loss of control.
f) Mandrel Mounted Wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck. If the mandrel
is insufficiently held and/or the overhang of the
wheel is too long, the Mounted Wheel may become
loose and be ejected at high velocity.
g) Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks, sanding
drum for cracks, tear or excess wear, wire
brush for loose or cracked wires. If power
tool or accessory is dropped, inspect for
damage or install an undamaged accessory.
After inspecting and installing an accessory,
position yourself and bystanders away from
the plane of the rotating accessory and run
the power tool at maximum no-load speed for
one minute. Damaged accessories will normally
break apart during this test time.
h) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations. The dust mask
or respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken accessory
may fly away and cause injury beyond immediate
area of operation.
j) Hold power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal
5
en ENGLISH
parts of the power tool “live” and could give the
operator an electric shock.
k) Always hold the tool firmly in your hands
during the start-up. The reaction torque of the
motor, as it accelerates to full speed, can cause
the tool to twist.
l) Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one
hand and the tool in the other hand while in
use. Clamping a small workpiece allows you to use
your hands to control the tool. Round material such
as dowel rods, pipes or tubing have a tendency to
roll while being cut, and may cause the bit to bind
or jump toward you.
m) Position the cord clear of the spinning
accessory. If you lose control, the cord may be cut
or snagged and your hand or arm may be pulled
into the spinning accessory.
n) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull
the power tool out of your control.
o) After changing the bits or making any
adjustments, make sure the collet nut, chuck
or any other adjusting devices are securely
tightened. Loose adjustment devices can
unexpectedly shift, causing loss of control, loose
rotating components will be violently thrown.
p) 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.
q) Regularly clean the power tool’s air vents.
The motor’s fan will draw dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
r) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
s) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
6
4.2 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 movement 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 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 control
kickback forces, if proper precautions are taken.
b) Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp edges
or bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
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 direction
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.
e) When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide cutters,
always have the work securely clamped. These
wheels will grab if they become slightly canted in
the groove, and can kickback. When a cut-off wheel
grabs, the wheel itself usually breaks. When a rotary
file, high-speed cutter or tungsten carbide cutter
grabs, it may jump from the groove and you could
lose control of the tool.
4.3
Safety warnings specific for grinding
and abrasive cutting-off operations:
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications. For example: do not grind with the
side of a cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
b) For threaded abrasive cones and plugs
use only undamaged wheel mandrels with an
unrelieved shoulder flange that are of correct
size and length. Proper mandrels will reduce the
possibility of breakage.
c) Do not “jam” a cut-off wheel or apply
excessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility to
twisting or snagging of the wheel in the cut and the
possibility of kickback or wheel breakage.
d) Do not position your hand in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from
your hand, the possible kickback may propel the
spinning wheel and the power tool directly at you.
e) When wheel is pinched, snagged or when
interrupting a cut for any reason, switch
off the power tool and hold the power tool
motionless until the wheel comes to a
complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel
is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate
the cause of wheel pinching or snagging.
f) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
g) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
h) Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
4.4
Safety warnings specific for wire
brushing operations:
a) Be aware that wire bristles are thrown by
the brush even during ordinary operation. Do
not overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) Allow brushes to run at operating speed for
at least one minute before using them. During
this time no one is to stand in front or in line
with the brush. Loose bristles or wires will be
discharged during the run-in time.
c) Direct the discharge of the spinning wire
brush away from you. Small particles and tiny
wire fragments may be discharged at high velocity
during the use of these brushes and may become
imbedded in your skin.
4.5
Additional Safety Instructions
WARNING – Always wear protective
goggles.
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Abrasives must be stored and handled with care in
accordance with the manufacturer’s instructions.
Never use parting grinder discs for roughing work.
Do not apply pressure to the side of parting grinder
discs.
The workpiece must lay flat and be secured
against slipping, e.g. using clamps. Large
workpieces must be supported adequately.
Keep hands away from the rotating tool! Remove
swarf and similar material only when the machine
is at a standstill.
Prior to use, ensure that the coated abrasive is
properly fitted and secured. Run the tool in idling
for 60 seconds in a safe position and bring to
a standstill immediately if there are significant
vibrations or if other deficiencies are determined.
If such a situation occurs, check the machine to
determine the cause.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inflammable substances.
ENGLISH en
Endangered areas must be protected with flameresistant covers. Make sure that fire-risk areas are
always provided with suitable fire extinguishers.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first disconnect the
power tool from the mains supply (use non-metallic
objects) and avoid damaging internal components.
Damaged, eccentric or vibrating tools must not be
used.
For safety reasons, always ensure the rubber
sleeve is fitted while you work (4).
Pull the plug out of the plug socket before any
adjustments, conversions or servicing are
performed.
During machining, of metals in
particular, conductive dust can form
deposits inside the machine. This can lead to the
transfer of electrical energy onto the machine
housing. This can mean a temporary danger of
electric shocks. This is why it is necessary when
the machine is running 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.
We recommend using a stationary extractor
system and connecting a residual current circuitbreaker (FI) upstream. When the machine is shut
down via the FI circuit-breaker, it must be checked
and cleaned. For information on cleaning the
motor, see chapter 8. Cleaning.
Reducing dust exposure:
WARNING - Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
- Lead from lead-based paints,
- Crystalline silica from bricks and cement and
other masonry products, and
- Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a
well ventilated area, and work with approved
safety equipment, such as those dust masks that
are specially designed to filter out microscopic
particles.
This also applies to dust from other materials such
as some timber types (like oak or beech dust),
metals, asbestos. Other known diseases are e.g.
allergic reactions, respiratory diseases. Do not let
dust enter the body.
Observe the relevant guidelines and national
regulations for your material, staff, application and
place of application (e.g. occupational health and
safety regulations, disposal).
Collect the particles generated at the source, avoid
deposits in the surrounding area.
Use suitable accessories for special work. In this
way, fewer particles enter the environment in an
uncontrolled manner.
7
en ENGLISH
Use a suitable extraction unit.
Reduce dust exposure with the following
measures:
- do not direct the escaping particles and the
exhaust air stream at yourself or nearby persons
or on dust deposits,
- use an extraction unit and/or air purifiers,
- ensure good ventilation of the workplace and
keep clean using a vacuum cleaner. Sweeping or
blowing stirs up dust.
- Vacuum or wash the protective clothing. Do not
blow, beat or brush.

刷或其他配件而产生的突然反作用力。卡住或缠绕
会引起旋转配件的迅速堵转，随之使失控的电动工
具在卡住点产生与配件旋转方向相反的运动。
例如，如果砂轮被工件缠绕或卡住，伸入卡住点的
砂轮边缘可能会进入材料表面而引起砂轮爬出或反
弹。砂轮可能飞向或飞离操作者，这取决于砂轮在
卡住点的运动方向。在此条件下砂轮也可能碎裂。
反弹是电动工具误用和／或不正确操作工序或条件
的结果。此情况可通过采取以下给出的适当预防措
施得以避免。
a) 保持紧握电动工具，使你的身体和手臂处于正确
状态以抵抗反弹力。如采取合适的预防措施，操作
者就可以控制反力矩或反弹力。
b) 当在尖角、锐边等处作业时要特别小心。避免配
件的弹跳和缠绕。尖角、锐边和弹跳具有缠绕旋转
配件的趋势并引起反弹的失控。
c) 请勿使用带齿锯片。这些锯片会产生频繁的反弹
和失控。
d) 务必依照尖端离开材料的方向将配件插入材料
（也就是与切屑退出的方向）。如果电动工具插入
的方向不正确，工具的尖端将远离工件，而使工具
朝这个方向前进。
e) 使用旋转锉刀、小型切割滚轮、高速铣削功具或
硬金属铣削工具时，务必将工件固定夹紧于定位。
即使在凹槽中仅稍微倾斜，也可能使这些工具卡死
对磨削和砂磨切割操作的专用安全警告：
a) 务必仅使用您的电动工具授权使用的砂轮类型，
并且只能在建议的应用范围内加以应用。例如：切
勿使用切割轮的侧边进行磨削。切割砂轮适用于周
边磨削。施加到砂轮侧面的力可能会使其碎裂。
b) 若是圆锥和圆柱螺纹带柄砂轮，务必仅使用完好
无损且尺寸及长度正确，同时肩部无下凹的心轴。
使用适当的心轴可降低破裂的风险。
c) 不要“夹”住切割砂轮或施加过大的压力。不要
试图做过深的切割。给砂轮施加过应力增加了砂轮
在切割时的负载，容易缠绕或卡住，增加了反弹或
砂轮爆裂的可能性。
d) 避免将手放在旋转砂轮的后方或前方。当把砂
轮从操作者身边的操作点移开时，可能的反弹会使
旋转砂轮和电动工具朝你推来。
e) 当砂轮被卡住或无论任何原因而中断切割时，
关掉电动工具并握住工具不要动，直到砂轮完全停
止。决不要试图当砂轮仍然运转时使切割砂轮脱离
切割，否则会发生反弹。调查并采取校正措施以消
除砂轮卡住的原因。
f) 不能在工件上重新起动切割操作。让砂轮达到全
速后再小心地重新进入切割。如果电动工具在工件
上重新起动，砂轮可能会卡住、爬出或反弹。
g) 支撑住板材或超大工件可使得砂轮卡住和反弹的
危险降到最低限度。大工件凭借自重而下垂。必须
在工件靠近切割线处和砂轮两侧近工件边缘处放置
支承。
h) 当进行“盲切割”进入墙体或其他盲区时要格外
小心。伸出的砂轮可能会割到煤气管或水管，电线
或由此引起反弹的物体。
4.4
钢丝刷操作的专用安全警告：
a) 要意识到即使正常操作时钢丝线也会随刷子甩
出。不要对钢丝刷施加过大的负荷而使得钢丝线承
受过应力。钢丝线可能会轻易刺入薄的衣服和／或
皮肤内。
b) 使用钢丝刷之前，请先让它以操作速度运转至少
一分钟。在这段时间内，务必不要让任何人站在钢
丝刷前方或与钢丝刷成一直线。转入期间松脱的钢
丝刷毛可能会掉出。
c) 让旋转钢丝刷远离您。使用这些钢丝刷时务必记
住，在高速旋转下，小碎屑或钢丝刷毛可能弹出并
穿透皮肤。
