SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
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.
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. 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.
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.

9ENGLISH
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

3. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another.Shortingthebatterytermi-
nalstogethermaycauseburnsorare.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help.Liquidejectedfromthebatterymaycause
irritationorburns.
5. Do not use a battery pack or tool that is dam-
aged or modied.Damagedormodiedbatteries
mayexhibitunpredictablebehaviourresultingin

Cordless grinder safety warnings
Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-O󰀨 Operations:
1. This power tool is intended to function as a
grinder, sander, wire brush or cut-o󰀨 tool.
Read all safety warnings, instructions, illus-
trations 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.
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.

10 ENGLISH
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, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory 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 acces-
sories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.
Fragmentsofworkpieceorofabrokenaccessory
mayyawayandcauseinjurybeyondimmediate
area of operation.
10. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a “live” wire will also make
exposed metal parts of the power tool “live” and
could give the operator an electric shock.
11. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessorymaygrabthesurfaceandpullthe
power tool out of your control.
12. 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.
13. 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.
14. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
15. 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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.
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.

11 ENGLISH
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.
Additional Safety Warnings:
1. When using depressed centre grinding wheels,
be sure to use only berglass-reinforced
wheels.
2. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product
mayresultinseriouspersonalinjury.
3. Be careful not to damage the spindle, the
ange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
4. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
5. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
6. Use the specied surface of the wheel to per-
form the grinding.
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
9. Do not touch accessories immediately after
operation; it may be extremely hot and could
burn your skin.
10. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
11. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
12. Use only anges specied for this tool.
13. For tools intended to be tted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
14. Check that the workpiece is properly
supported.
15. Pay attention that the wheel continues to
rotate after the tool is switched o󰀨.
16. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
17. Do not use the tool on any materials contain-
ing asbestos.
18. When use cut-o󰀨 wheel, always work with
the dust collecting wheel guard required by
domestic regulation.
19. Cutting discs must not be subjected to any
lateral pressure.
20. Do not use cloth work gloves during operation.
Fibersfromclothglovesmayenterthetool,which
causestoolbreakage.
21. Make sure there are no electrical cables, water
pipes, gas pipes etc. that could cause a hazard
if damaged by use of the tool.
SAVE THESE INSTRUCTIONS.

工作场地的安全
1. 保持工作场地清洁和明亮。杂乱和黑暗
的场地会引发事故。
2. 不要在易爆环境，如有易燃液体、气体
或粉尘的环境下操作电动工具。电动工
具产生的火花会点燃粉尘或气体。
3. 操作电动工具时，远离儿童和旁观者。注
意力不集中会使你失去对工具的控制。
电气安全
1. 电动工具插头必须与插座相配。绝不能
以任何方式改装插头。需接地的电动工
具不能使用任何转换插头。未经改装的
插头和相配的插座将降低电击风险。
2. 避免人体接触接地表面，如管道、散热
片和冰箱。如果你身体接触接地表面会
增加电击风险。
3. 不得将电动工具暴露在雨中或潮湿环境
中。水进入电动工具将增加电击风险。
4. 不得滥用软线。绝不能用软线搬运、拉
动电动工具或拔出其插头。使软线远离
热源、油、锐边或运动部件。受损或缠
绕的软线会增加电击风险。
5. 当在户外使用电动工具时，使用适合户
外使用的延长线。适合户外使用的电线
将降低电击风险。
6. 如果无法避免在潮湿环境中操作电动工
具 ，应 使 用 带 有 剩 余 电 流 装 置（ RCD）保
护的电源。RCD的使用可降低电击风险。
7. 电动工具会产生对用户无害的电磁场
（EMF）。但是，起搏器和其他类似医
疗设备的用户应在操作本电动工具前咨
询其设备的制造商和／或医生寻求建议。
人身安全
