中文 | 7 不推荐用该电动工具进行抛光。 电动工具不按指定
的功能去操作，可能发生危险和引起人身伤害。
 不使用非工具制造商推荐和专门设计的附件。 否则该附件可能被装到你的电动工具上，而它不能保证
安全操作。
 附件的额定速度必须至少等于电动工具上标出的最大速度。 附件以比其额定速度大的速度运转会发生
爆裂和飞溅。
 附件的外径和厚度必须在电动工具额定能力范围之内。 不正确的附件尺寸不能得到充分防护或控制。
 砂轮、法兰盘、靠背垫或任何其他附近的轴孔尺寸
必须适合于安装到电工工具的主轴上。 带轴孔的、
与电动工具安装件不配的附件将会失稳、过度振动
并会引起失控。
 不要使用损坏的附件。在每次使用前要检查附件，
例如砂轮是否有碎片和裂缝，靠背垫是否有裂缝，撕裂或过度磨损，钢丝刷是否松动或金属丝是否断裂。如果电动工具或附件跌落了，检查是否有损坏
或安装没有损坏的附件。检查和安装附件后，让自
己和旁观者的位置远离旋转附件的平面，并以电动
工具最大空载速度运行 1 分钟。 损坏的附件通常在该试验时会碎裂。
 戴上防护用品。根据适用情况，使用面罩，安全护目镜或安全眼镜。适用时，戴上防尘面具，听力保护器，手套和能挡小磨料或工件碎片的工作围裙。
眼防护罩必须挡住各种操作产生的飞屑。防尘面具或口罩必须能够过滤操作产生的颗粒。长期暴露在高强度噪音中会引起失聪。
 让旁观者与工作区域保持一安全距离。任何进入工
作区域的人必须戴上防护用品。 工件或破损附件的碎片可能会飞出并引起紧靠着操作区域的旁观者的伤害。切割附件触及带电导线会使电动工具外露的
金属零件带电，并使操作者触电。
 当在切割附件有可能切割到暗线或自身电线的场所进行操作时，只能通过绝缘握持面来握住电动工具。 切割附件碰到一根带电导线可能会使电动工具
外露的金属零件带电并使操作者发生电击危险。
 使软线远离旋转的附件。 如果控制不当，软线可能
被切断或缠绕，并使得你的手或手臂可能被卷入旋
转附件中。
 直到附件完全停止运动才放下电动工具。并且不得
使用任何外力迫使金刚石切割片停转。 旋转的附件可能会抓住表面并拉动电动工具而让你失去对工具
的控制。
 当携带电动工具时不要开动它。 意外地触及旋转附件可能会缠绕你的衣服而使附件伤害身体。
 经常清理电动工具的通风口。 电动机风扇会将灰尘吸进机壳，过多的金属粉末沉积会导致电气危险。
 不要在易燃材料附近操作电动工具。 火星可能会点
燃这些材料。

Bosch Power Tools

 不要使用需用冷却液的附件。 用水或其他冷却液可能导致电腐蚀或电击。
反弹和相关警告 反弹是因卡住或缠绕住的旋转砂轮，靠背垫，钢丝
刷或其他附件而产生的突然反作用力。卡住或缠绕会引起旋转附件的迅速堵转，随之使失控的电动工
具在卡住点产生与附件旋转方向相反的运动。
例如，如果砂轮被工件缠绕或卡住了，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。可以通过采取以下给出的适当预防措施得以避免。
 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。如有辅助手柄，则要一直使用，
以便最大限度控制住起动时的反弹力或反力矩。 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。
 绝不能将手靠近旋转附件。 附件可能会反弹碰到手。
 不要站在发生反弹时电动工具可能移动到的地方。
反弹将在缠绕点驱使工具逆砂轮运动方向运动。
 当在尖角、锐边等处作业时要特别小心。避免附件
的弹跳和缠绕。 尖角，锐边和弹跳具有缠绕旋转附件的趋势并引起反弹的失控。
 不要附装上锯链、木雕刀片或带齿锯片。 这些锯片会产生频繁的反弹和失控。
对磨削和砂磨切割操作的专用安全警告
 只使用所推荐的砂轮型号和为选用砂轮专门设计的护罩。 不是为电动工具设计的砂轮不能充分得到防护，是不安全的。
 安装弯曲的砂轮时，砂轮的研磨面不可以突出于防
护罩缘之外。 防护罩无法遮蔽因为安装不当而突出于防护罩缘之外的砂轮。
 防护必须牢固地装在电动工具上，且放置得最具安
全性，只有最小的砂轮部分暴露在操作人面前。 护罩帮助操作者免于受到爆裂砂轮片和偶然触及砂轮的危险。
 砂轮只用作推荐的用途。例如：不要用切割砂轮的
侧面进行磨削。 施加到砂轮侧面的力可能会使其碎
裂。
 始终为所选砂轮选用未损坏的，有恰当规格和形状
的砂轮法兰盘。 合适的砂轮法兰盘支承砂轮可以减
小砂轮破裂的可能性。切割砂轮的法兰盘可以不同
于砂轮法兰盘。
 不要使用从大规格电动工具上用剩的磨损砂轮。 用于大规格电动工具上的砂轮不适于较小规格工具的
高速工况并可能会爆裂。

8 | 中文对砂轮切割操作的附加专用安全警告
 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。
 身体不要对着旋转砂轮，也不要站在其后。 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。
 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。
 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。
 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。

 加工石材时必须使用检验合格的石尘专用吸尘装置。 使用此装置可以预防由灰尘引起的伤害。
 切割石材时必须使用导引板。 如果缺少侧面导引，
切割片容易歪斜，並造成回击。
 工作时必须用双手握紧电动工具，並且要确保立足稳固。 使用双手比较能够握稳电动工具。
 在研磨/割片尚未冷却之前，切勿持握研磨/割片。
工作时切割片会变得非常炙热。
 固定好工件。 使用固定装置或老虎钳固定工件，会比用手持握工件更牢固。
 工作场所必须保持清洁。 不同的工作尘经过混合后
容易产生化学反应，十分危险。轻金属尘容易著火或引起爆炸。
 勿使用电线已经损坏的电动工具。如果电源电线在
工作中受损，千万不可触摸损坏的电线，並马上拔出插头。 损坏的电线会提高使用者触电的危险。

产品和功率描述
阅读所有的警告提示和指示。 如未确实
遵循警告提示和指示，可能导致电击，火灾并且 / 或其他的严重伤害。

 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。
砂光操作的专用安全警告
 当砂光时，不要使用超大砂盘纸。选用砂盘纸时应
按照制造商的推荐。 超出砂光垫盘的大砂盘纸有撕
裂的危险并且会引起缠绕、砂盘的撕裂或反弹。
钢丝刷操作的专用安全警告
 要意识到即使正常操作时钢丝线也会从刷子甩出。
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。
 如果建议钢丝刷使用护罩，则不允许该护罩对钢丝轮或钢丝刷有任何干扰。 钢丝轮或钢丝刷在工作负
荷和离心力作用下直径会变大。
其它的警告事项请佩戴护目镜。

EnglishSafety Notes
General Power Tool Safety Warnings
Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless)power tool.

WARNINGWork area safety Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
 Do not operate power tools in explosive atmospheres,such as in the presence of flammable liquids, gases ordust. Power tools create sparks which may ignite the dust
or fumes.
 Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs withearthed (grounded) power tools. Unmodified plugs andmatching outlets will reduce risk of electric shock.
 Avoid body contact with earthed or grounded surfaces,such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body isearthed or grounded.
 Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
 Do not abuse the cord. Never use the cord for carrying,pulling or unplugging the power tool. Keep cord awayfrom heat, oil, sharp edges and moving parts. Damaged
or entangled cords increase the risk of electric shock.
 When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitablefor outdoor use reduces the risk of electric shock.
 If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protectedsupply. Use of an RCD reduces the risk of electric shock.
Personal safety
 Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
 Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
Bosch Power Tools

used for appropriate conditions will reduce personal injuries.
 Prevent unintentional starting. Ensure the switch is in
the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
 Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
 Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
 Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away frommoving parts. Loose clothes, jewellery or long hair can becaught in moving parts.
 If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Power tool use and care
 Do not force the power tool. Use the correct power toolfor your application. The correct power tool will do thejob better and safer at the rate for which it was designed.
 Do not use the power tool if the switch does not turn iton and off. Any power tool that cannot be controlled withthe switch is dangerous and must be repaired.
 Disconnect the plug from the power source and/or thebattery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk ofstarting the power tool accidentally.
 Store idle power tools out of the reach of children anddo not allow persons unfamiliar with the power tool orthese instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
 Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any othercondition that may affect the power tool’s operation. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
 Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bindand are easier to control.
 Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into accountthe working conditions and the work to be performed.
Use of the power tool for operations different from thoseintended could result in a hazardous situation.
Service Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety Warnings for Angle Grinder
Safety Warnings common for Grinding, Sanding, Wire
Brushing or Abrasive Cutting Off Operations
 This power tool is intended to function as a grinder,
sander, wire brush 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.
 Operations such as polishing are not recommended tobe performed with this power tool. Operations for which
the power tool was not designed may create a hazard andcause personal injury.
 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.
 The rated speed of the accessory must be at least equal
to the maximum speed marked on the power tool. Accessories running faster than their rated speed can breakand fly apart.
 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
guarded or controlled.
 Threaded mounting of accessories must match thegrinder spindle thread. For accessories mounted byflanges, the arbour hole of the accessory must fit thelocating diameter of the flange. Accessories that do notmatch the mounting hardware of the power tool will run out
of balance, vibrate excessively and may cause loss of control.
 Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips
and cracks, backing pad 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.
 Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop 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.
 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

1 609 92A 2CK | (16.1.17)

broken accessory may fly away and cause injury beyond
immediate area of operation.
 Hold the 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 parts of the power tool “live” and could give the operator an electric shock.
 Position the cord clear of the spinning accessory. If you
lose control, the cord may be cut or snagged and your handor arm may be pulled into the spinning wheel.
 Never lay the power tool down until the accessory hascome to a complete stop. The spinning wheel may grab
the surface and pull the power tool out of your control.
 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.
 Regularly clean the power tool’s air vents. The motor’s
fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
 Do not operate the power tool near flammable materials. Sparks could ignite these materials.
 Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Kickback and related warnings
 Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, 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 at the point of the binding.
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 materialcausing 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.
 Maintain a firm grip on the power tool and position yourbody and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum
control over kickback or torque reaction during
start-up. The operator can control torque reactions or
kickback forces, if proper precautions are taken.
 Never place your hand near the rotating accessory. Accessory may kickback over your hand.
 Do not position your body in the area where power tool
will move if kickback occurs. Kickback will propel thetool in direction opposite to the wheel’s movement at the
point of snagging.
Bosch Power Tools

OBJ_BUCH-782-007.book Page 21 Monday, January 16, 2017 10:36 AM

English | 21
 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 therotating accessory and cause loss of control or kickback.
 Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.
Safety warnings specific for Grinding and Abrasive Cutting-Off operations
 Use only wheel types that are recommended for yourpower tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.
 The grinding surface of the centre depressed wheels
must be mounted below the plane of the guard lip. An
improperly mounted wheel that projects through the planeof the guard lip cannot be adequately protected.
 The guard must be securely attached to the power tooland positioned for maximum safety, so the least
amount of wheel is exposed towards the operator. The
guard helps to protect operator from broken wheel fragments, accidental contact with wheel and sparks that
could ignite clothing.
 Wheels must be used only for recommended applications. For example: do not grind with the side of the
cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding; side forces applied to these wheels
may cause them to shatter.
 Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may bedifferent from grinding wheel flanges.
 Do not use worn down reinforced wheels from larger
power tools. Wheels intended for larger power tools are
not suitable for the higher speed of a smaller tool and may
burst.
Additional safety warnings specific for abrasive cutting
off operations
 Do not “jam” the 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 binding of the wheel in the cut and thepossibility of kickback or wheel breakage.
 Do not position your body in line with and behind therotating wheel. When the wheel, at the point of operation,is moving away from your body, the possible kickback may
propel the spinning wheel and the power tool directly atyou.
 When wheel is binding 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 fromthe cut while the wheel is in motion otherwise kickback
may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
Bosch Power Tools

 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 thepower tool is restarted in the workpiece.
 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.
 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 thatcan cause kickback.
Safety warnings specific for sanding operations
 Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard andmay cause snagging, tearing of the disc, or kickback.
Safety warnings specific for wire brushing operations
 Be aware that wire bristles are thrown by the brusheven during ordinary operation. Do not overstress thewires by applying excessive load to the brush. The wire
bristles can easily penetrate light clothing and/or skin.
 If the use of a guard is recommended for wire brushing,
do not allow any interference of the wire wheel orbrush with the guard. Wire wheel or brush may expand indiameter due to work load and centrifugal forces.
Additional safety warnings
Wear safety goggles.

 Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead to fireand electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or
may cause an electric shock.
 Release the On/Off switch and set it to the off position
when the power supply is interrupted, e. g., in case of apower failure or when the mains plug is pulled. This prevents uncontrolled restarting.
 When working stone, use dust extraction. The vacuum
cleaner must be approved for the extraction of stone
dust. Using this equipment reduces dust-related hazards.
 Use a cutting guide when cutting stone. Without sideward guidance, the cutting disc can jam and cause kickback.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.

Product Features Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot whileworking.
 Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
 Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode.
 Never use the machine with a damaged cable. Do nottouch the damaged cable and pull the mains plug when
the cable is damaged while working. Damaged cables increase the risk of an electric shock.

Rotating the Machine Head
 Before any work on the machine itself, pull the mains
plug.
The machine head can berotated with respect tothe machine housing in
90° steps. In this manner, the On/Off switch
can be brought into a
more convenient position for special working
situations, e.g. for lefthanded persons.
Completely unscrew thefour screws. Rotate themachine head carefully,
without removing it from the housing, to the new position.
Screw in and tighten the four screws again.

Dust/Chip Extraction
 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for thematerials to be worked.

Operation
Starting Operation
 Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
 Hold power tool by insulated gripping surfaces 23 andauxiliary handle 5 only. The accessory may contact hidden wiring or its own cord. Accessory contacting a “live”
wire may make exposed metal parts of the power tool “live”
and shock the operator.
When operating the machine with power from mobile generators that do not have sufficient reserve capacity or are notequipped with suitable voltage control with starting current
amplification, loss of performance or untypical behavior canoccur upon switching on.
Please observe the suitability of the power generator being
used, particularly with regard to the mains voltage and frequency.
Switching On and Off
To start the power tool, push the On/Off switch 2 forwards.
To lock the On/Off switch 2, press the On/Off switch 2 downat the front until it latches.
To switch off the power tool, release the On/Off switch 2 or,if it is locked, briefly push down the back of the On/Off switch
2 and then release it.
To save energy, only switch the power tool on when using it.
 Check grinding tools before using. The grinding tool
must be mounted properly and be able to move freely.
Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grinding tools. Damaged grinding tools can burst and cause injuries.

Speed preselection (GWS 7-100 ET/GWS 7-125 ET)

26 | English
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot whileworking.
 Do not use the power tool with a cut-off stand.
Rough Grinding Never use a cutting disc for roughing.
The best roughing results are achieved when setting the machine at an angle of 30° to 40°. Move the machine back andforth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
Flap Disc
With the flap disc (accessory), curved surfaces and profiles
can be worked.
Flap discs have a considerably higher service life, lower noiselevels and lower sanding temperatures than conventional
sanding sheets.
Cutting Metal
 For cutting with bonded abrasives, always use the protection guard for cutting 14.
When cutting, work with moderate feed, adapted to the material being cut. Do not exert pressure onto the cutting disc, tilt
or oscillate the machine.
Do not reduce the speed of running down cutting discs by applying sideward pressure.
The machine must always work in an upgrinding motion. Otherwise, the danger exists
of it being pushed uncontrolled out of thecut.
When cutting profiles
and square bar, it is best
to start at the smallest
cross section.

Cutting Stone
 Provide for sufficient dust extraction when cuttingstone.
 The machine may be used only for dry cutting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
Operate the machine only with dust extraction and additionally wear a dust protection mask.
The vacuum cleaner must be approved for the extraction ofmasonry dust. Bosch provides suitable vacuum cleaners.

1 609 92A 2CK | (16.1.17)

Switch on the machineand place the front partof the cutting guide on
the workpiece. Slide themachine with moderate
feed, adapted to the material to be worked.
For cutting expeciallyhard material, e. g., concrete with high pebble
content, the diamondcutting disc can overheat and become damaged as a result. This isclearly indicated by circular sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and allow the diamond cutting disc to cool by running the machine for a shorttime at maximum speed with no load.
Noticeable decreasing work progress and circular sparking
are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e. g. lime-sandbrick) can resharpen the disc again.
Information on Structures
Slots in structural walls are subject to the Standard DIN 1053
Part 1, or country-specific regulations.
These regulations are to be observed under all circumstances. Before beginning work, consult the responsible structural
engineer, architect or the construction supervisor.

Maintenance and Service
Maintenance and Cleaning Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machineand ventilation slots clean.
 In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When working metals, conductive dust can settle in the interior of thepower tool. The total insulation of the power tool can be impaired.
If the replacement of the supply cord is necessary, this has tobe done by Bosch or an authorized Bosch service agent in order to avoid a safety hazard.
Please store and handle the accessory(-ies) carefully.
