tions, illustrations and specications provided

with this power tool. Failure to follow all instructions

listedbelowmayresultinelectricshock,reand/or

seriousinjury.

Save all warnings and instruc-

tions for future reference.

The term “power tool” in the warnings refers to your

mains-operated(corded)powertoolorbattery-operated

(cordless) power tool.

Work area safety

1. Keep work area clean and well lit.Clutteredor

dark areas invite accidents.

2. Do not operate power tools in explosive atmo-

spheres, such as in the presence of ammable

liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

3. Keep children and bystanders away while

operating a power tool. Distractions can cause

you to lose control.

8ENGLISH

Electrical safety

1. Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any

adapter plugs with earthed (grounded) power

tools. Unmodiedplugsandmatchingoutletswill

reduce risk of electric shock.

2. Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and

refrigerators. There is an increased risk of elec-

tricshockifyourbodyisearthedorgrounded.

3. Do not expose power tools to rain or wet con-

ditions. Water entering a power tool will increase

the risk of electric shock.

4. Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges

or moving parts. Damaged or entangled cords

increase the risk of electric shock.

5. When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of

acordsuitableforoutdoorusereducestheriskof

electric shock.

6. If operating a power tool in a damp location

is unavoidable, use a residual current device

(RCD) protected supply.UseofanRCDreduces

the risk of electric shock.

7. Use of power supply via an RCD with a rated

residual current of 30 mA or less is always

recommended.

8. Power tools can produce electromagnetic

elds (EMF) that are not harmful to the user.

However, users of pacemakers and other similar

medical devices should contact the maker of their

deviceand/ordoctorforadvicebeforeoperating

this power tool.

9. Do not touch the power plug with wet hands.

10. If the cord is damaged, have it replaced by the

manufacturer or his agent in order to avoid a

safety hazard.

Personal safety

1. 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 inuence of drugs, alcohol or med-

ication. A moment of inattention while operating

powertoolsmayresultinseriouspersonalinjury.

2. Use personal protective equipment. Always

wear eye protection. Protective equipment such

as a dust mask, non-skid safety shoes, hard hat or

hearing protection used for appropriate conditions

willreducepersonalinjuries.

3. Prevent unintentional starting. Ensure the

switch is in the o-position before connecting

to power source and/or battery pack, picking

up or carrying the tool.Carryingpowertoolswith

yourngerontheswitchorenergisingpowertools

that have the switch on invites accidents.

4. 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.

5. Do not overreach. Keep proper footing and

balance at all times.Thisenablesbettercontrol

of the power tool in unexpected situations.

6. Dress properly. Do not wear loose clothing or

jewellery. Keep your hair and clothing away

from moving parts.Looseclothes,jewelleryor

longhaircanbecaughtinmovingparts.

7. 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.

8. Do not let familiarity gained from frequent use

of tools allow you to become complacent and

ignore tool safety principles. A careless action

cancausesevereinjurywithinafractionofa

second.

9. Always wear protective goggles to protect

your eyes from injury when using power tools.

The goggles must comply with ANSI Z87.1 in

the USA, EN 166 in Europe, or AS/NZS 1336

in Australia/New Zealand. In Australia/New

Zealand, it is legally required to wear a face

shield to protect your face, too.

It is an employer's responsibility to enforce

the use of appropriate safety protective equip-

ments by the tool operators and by other per-

sons in the immediate working area.

Power tool use and care

1. Do not force the power tool. Use the correct

power tool for your application. The correct

powertoolwilldothejobbetterandsaferatthe

rate for which it was designed.

2. Do not use the power tool if the switch does

not turn it on and o. Any power tool that cannot

becontrolledwiththeswitchisdangerousand

mustberepaired.

3. Disconnect the plug from the power source

and/or remove the battery pack, if detachable,

from the power tool before making any adjust-

ments, changing accessories, or storing power

tools. Such preventive safety measures reduce

the risk of starting the power tool accidentally.

4. Store idle power tools out of the reach of chil-

dren and do not allow persons unfamiliar with

the power tool or these instructions to operate

the power tool. Power tools are dangerous in the

hands of untrained users.

5. Maintain power tools and accessories. Check

for misalignment or binding of moving parts,

breakage of parts and any other condition that

may aect the power tool’s operation. If dam-

aged, have the power tool repaired before use.

Manyaccidentsarecausedbypoorlymaintained

power tools.

9ENGLISH

6. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

arelesslikelytobindandareeasiertocontrol.

7. Use the power tool, accessories and tool bits

etc. in accordance with these instructions, tak-

ing into account the working conditions and

the work to be performed. Use of the power tool

foroperationsdierentfromthoseintendedcould

result in a hazardous situation.

8. Keep handles and grasping surfaces dry,

clean and free from oil and grease. Slippery

handles and grasping surfaces do not allow for

safe handling and control of the tool in unexpected

seriousinjury.

2. Operations such as polishing are not rec-

ommended to be performed with this power

tool. Operations for which the power tool was not

designed may create a hazard and cause per-

sonalinjury.

3. Do not use accessories which are not speci-

cally designed and recommended by the tool

manufacturer.Justbecausetheaccessorycan

beattachedtoyourpowertool,itdoesnotassure

safe operation.

4. 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breakandyapart.

5. 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.

6. Threaded mounting of accessories must

match the grinder spindle thread. For acces-

sories mounted by anges, the arbour hole of

the accessory must t the locating diameter

of the ange. 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.

7. Do not use a damaged accessory. Before each

use inspect the accessory such as abrasive

wheels for chips and cracks, and wire brush

for loose or cracked wires. If power tool or

accessory is dropped, inspect for damage or

install an undamaged accessory. After inspect-

ing and installing an accessory, position your-

self 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.

8. Wear personal protective equipment.

Depending on application, use face shield,

safety goggles or safety glasses. As appro-

priate, wear dust mask, hearing protectors,

gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments.

Theeyeprotectionmustbecapableofstopping

yingdebrisgeneratedbyvariousoperations.

Thedustmaskorrespiratormustbecapableof

ltratingparticlesgeneratedbyyouroperation.

Prolonged exposure to high intensity noise may

cause hearing loss.

9. Keep bystanders a safe distance away from

work area. Anyone entering the work area

must wear personal protective equipment.

Kickback and Related Warnings

Kickbackisasuddenreactiontoapinchedorsnagged

rotatingwheel,backingpad,brushoranyotheracces-

sory. Pinching or snagging causes rapid stalling of the

rotating accessory which in turn causes the uncon-

trolledpowertooltobeforcedinthedirectionopposite

oftheaccessory’srotationatthepointofthebinding.

10 ENGLISH

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precautionsasgivenbelow.

1. Maintain a rm grip on the power tool and

position your body 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 kick-

backforces,ifproperprecautionsaretaken.

2. Never place your hand near the rotating acces-

sory.Accessorymaykickbackoveryourhand.

3. Do not position your body in the area where

power tool will move if kickback occurs.

Kickbackwillpropelthetoolindirectionopposite

to the wheel’s movement at the point of snagging.

4. 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.

5. Do not attach a saw chain woodcarving blade

or toothed saw blade.Suchbladescreatefre-

quentkickbackandlossofcontrol.

Safety Warnings Specic for Grinding and Abrasive

Cutting-O Operations:

1. Use only wheel types that are recommended

for your power tool and the specic guard

designed for the selected wheel. Wheels for

whichthepowertoolwasnotdesignedcannotbe

adequately guarded and are unsafe.

2. The grinding surface of centre depressed

wheels must be mounted below the plane of

the guard lip. An improperly mounted wheel that

projectsthroughtheplaneoftheguardlipcannot

beadequatelyprotected.

3. The guard must be securely attached to the

power tool and positioned for maximum safety,

so the least amount of wheel is exposed

towards the operator. The guard helps to protect

theoperatorfrombrokenwheelfragments,acci-

dental contact with wheel and sparks that could

ignite clothing.

4. Wheels must be used only for recommended

applications. For example: do not grind with

the side of cut-o wheel.Abrasivecut-owheels

are intended for peripheral grinding, side forces

applied to these wheels may cause them to

shatter.

5. Always use undamaged wheel anges that are

of correct size and shape for your selected

wheel.Properwheelangessupportthewheel

thusreducingthepossibilityofwheelbreakage.

Flangesforcut-owheelsmaybedierentfrom

grindingwheelanges.

6. Do not use worn down wheels from larger

power tools. Wheel intended for larger power tool

isnotsuitableforthehigherspeedofasmaller

toolandmayburst.

Additional Safety Warnings Specic for Abrasive

Cutting-O Operations:

1. Do not “jam” the cut-o wheel or apply exces-

sive 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thepossibil-

ityofkickbackorwheelbreakage.

2. Do not position your body in line with and

behind the rotating wheel. When the wheel, at

the point of operation, is moving away from your

body,thepossiblekickbackmaypropelthespin-

ning wheel and the power tool directly at you.

3. When wheel is binding or when interrupting

a cut for any reason, switch o the power

tool and hold the power tool motionless until

the wheel comes to a complete stop. Never

attempt to remove the cut-o wheel from the

cut while the wheel is in motion otherwise

kickback may occur. Investigate and take correc-

tiveactiontoeliminatethecauseofwheelbinding.

4. 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.

5. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick-

back. 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.

6. Use extra caution when making a “pocket cut”

into existing walls or other blind areas. The

protruding wheel may cut gas or water pipes, elec-

tricalwiringorobjectsthatcancausekickback.

Safety Warnings Specic for Sanding Operations:

1. Do not use excessively oversized sanding

disc paper. Follow manufacturers recommen-

dations, when selecting sanding paper. Larger

sandingpaperextendingbeyondthesanding

pad presents a laceration hazard and may cause

snagging,tearingofthediscorkickback.

Safety Warnings Specic for Wire Brushing

Operations:

1. 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.

2. If the use of a guard is recommended for wire

brushing, do not allow any interference of the

wire wheel or brush with the guard. Wire wheel

orbrushmayexpandindiameterduetoworkload

and centrifugal forces.

11 ENGLISH

反弹和相关警告

反弹是正在旋转的砂轮、垫片、钢丝刷或其

他配件卡滞或卡滞时突然产生的反作用力。

卡滞会导致旋转配件的快速停止，从而导致

在卡滞点处对失控的工具产生与配件旋转方

向相反的作用力。

中文简体

例如，如果工件使得砂轮卡滞，则进入卡滞

点的砂轮边缘将进入工件材料的表面，导致

砂轮跳出或弹出。根据砂轮在卡滞点的运动

方向，砂轮可能会跳向或远离操作者。在这

种情况下，砂轮也可能会破裂。

电动工具误操作和／或不正确的操作步骤或

操作条件将导致反弹，遵守以下所述的注意

事项即可避免。

1. 请牢固持握电动工具的把手，调整身体

和手臂位置以防止反弹力。如果提供了

辅助手柄，请务必使用，以在启动时最

大程度地控制反弹或转矩反作用力。如

果正确遵守注意事项，操作者可控制转

矩反作用力或反弹力。

2. 切勿将手靠近旋转的附件。附件可能会

反弹到您手上。

3. 请勿置身于发生反弹时电动工具可能移

动的区域内。反弹会在卡滞点处以与砂

轮运动方向相反的力作用于砂轮。

4. 当处理边角、锐利的边缘等处时请特别

小心。避免使附件跳跃和卡滞。边角、

锐利的边缘或附件发生跳跃可能会使旋

转的附件被钩住并导致工具失控或反弹。

5. 请勿安装锯链木雕锯片或齿状锯片。这些

锯片会发生频繁的反弹并导致工具失控。

专用于磨削和砂轮切割操作的安全警告：

1. 请仅使用被推荐用于您的电动工具的砂

轮以及专用于所选砂轮的砂轮罩。非专

用于本电动工具的砂轮无法得到足够的

防护并无法保证安全。

2. 钹形砂轮的砂磨表面必须安装在砂轮罩

边缘的平面之下。突出于砂轮罩边缘平

面的安装不当的砂轮将不能得到充分的

保护。

3. 砂轮罩必须牢固安装到电动工具上并放

置在最为安全的位置，使得砂轮外露的

部分尽可能地少。砂轮罩可防止操作者

被砂轮碎片划伤或意外接触到砂轮和可

能会点燃衣物的火星。

4. 仅可将砂轮用于推荐的应用情况。例如：

请勿用切割砂轮的侧面进行磨削。切割砂

轮用于进行外围磨削，对这些砂轮应用侧

力可能会导致其破碎。

5. 请务必使用未损坏的砂轮法兰，尺寸和

外形应符合您所选的砂轮。正确的砂轮

法兰可减少砂轮破裂的危险。切割砂轮

的法兰可能与磨削砂轮法兰有所不同。

6. 请勿使用从更大的电动工具上拆下来的

已磨损的砂轮。用于大型电动工具的砂

轮不适合小型工具的高速操作，可能会

爆裂。

专用于砂轮切割操作的附加安全警告：

1. 请勿“挤压”切割砂轮或对其过度施压。

请勿试图切割过深。对砂轮过度施压会

使负荷增加，使砂轮在切割时易于扭曲

或卡滞，也使发生反弹或砂轮破裂的可

能性增大。

2. 请勿与旋转的砂轮成一直线站立或站在

其后面。如果操作时砂轮的移动方向为

远离您，如果此时发生反弹，则可能会

迫使旋转的砂轮直接指向您。

3. 当砂轮卡滞或因任何原因中断切割操作

时，请关闭电动工具并将工具保持不动，

直至砂轮完全停止。当砂轮还在运动中

时，切勿试图将切割砂轮从工件中取出，

否则可能会造成反弹。研究并采取正确的

措施以避免砂轮卡滞。

4. 请勿在工件中重新启动切割操作。请等

到砂轮到达全速后再小心地重新进行切

割。如果电动工具在工件中重新启动，

则砂轮可能会卡滞、移动或反弹。

5. 请支撑面板或其他大型工件以最大限度

地降低砂轮卡滞和反弹的可能。大型工

件会因自身的重量而下陷。必须在工件

下面靠近切割线和砂轮两侧工件边缘放

置支撑件。

6. 当在墙壁或其他盲区进行“袖珍切割”

时请尤其小心。凸出的砂轮可能会切割

到气管或水管、电线或其他物体，从而

导致反弹。

专用于砂磨操作的安全警告：

1. 请勿使用尺寸过大的砂纸。选择砂纸时

请遵照制造商的推荐。大于砂盘的砂纸

会有破裂的危险并可能导致砂轮片的卡

滞、破裂或反弹。

专用于钢丝刷操作的安全警告：

1. 即使在正常操作时也请小心钢丝刷的钢

毛飞出。请勿使钢丝刷过载导致钢丝过

压。钢毛很容易穿透轻薄的衣服和／或

皮肤。

2. 如果建议为钢丝刷配备护罩，请勿使其影

响到钢丝轮或在带有护罩的情况下使用钢

丝刷。根据工作负荷和离心力作用，钢丝

轮或钢丝刷在直径上可能会有所伸展。

附加安全警告：

1. 当使用钹形砂轮时，请务必且仅可使用

玻璃钢砂轮。

2. 使用本磨光机时切勿使用机碗形砂轮。

此类砂轮不适用于本磨光机，强行使用

可能会导致严重的人身伤害。

中文简体

3. 注意避免损坏X-LOCK固定架。此部件

损坏可能会导致砂轮破裂。

4. 打开开关前，请确认砂轮未与工件接触。

5. 在实际的工件上使用工具之前，请先让

工具空转片刻。请注意，振动或摇摆可

能表示安装不当或砂轮不平衡。

6. 请使用砂轮的指定表面来执行磨削。

7. 运行中的工具不可离手放置。只可在手

握工具的情况下操作工具。

8. 操作之后，请勿立刻触摸工件，因为其

可能会非常烫，导致烫伤皮肤。

9. 操作之后，请勿立刻触摸附件，因为它

们可能会非常烫，从而导致烫伤皮肤。

10. 请遵照制造商的说明进行正确安装和使

用砂轮。请小心处理和存放砂轮。

11. 请勿使用分离式卸套或适配器来适配大

孔砂轮。

12. 检查并确认工件被正确支撑。

13. 请注意，关闭工具之后，砂轮还会继续

旋转。
