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.

6ENGLISH
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 off-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 off. 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 affect the power tool’s operation. If dam-
aged, have the power tool repaired before use.
Manyaccidentsarecausedbypoorlymaintained
power tools.
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 different from those intended could
result in a hazardous situation.

7ENGLISH
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
situations.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entangle-
ment of cloth work gloves in the moving parts may
resultinpersonalinjury.
Service
1. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2. Follow instruction for lubricating and chang-
ing accessories.
Cutter safety warnings
1. The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the oper-
ator. Position yourself and bystanders away
from the plane of the rotating wheel. The guard
helpstoprotectoperatorfrombrokenwheelfrag-
ments and accidental contact with wheel.
2. Use only diamond cut-off wheels for your
power tool.Justbecauseanaccessorycanbe
attached to your power tool, it does not assure
safe operation.
3. 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.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasivecut-off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 diameter for your selected wheel.
Properwheelangessupportthewheelthus
reducingthepossibilityofwheelbreakage.
6. 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.
7. The arbour size of wheels and anges must
properly t the spindle of the power tool.
Wheelsandangeswitharbourholesthatdonot
match the mounting hardware of the power tool
willrunoutofbalance,vibrateexcessivelyand
may cause loss of control.
8. Do not use damaged wheels. Before each
use, inspect the wheels for chips and cracks.
If power tool or wheel is dropped, inspect for
damage or install an undamaged wheel. After
inspecting and installing the wheel, position
yourself and bystanders away from the plane
of the rotating wheel and run the power tool
at maximum no load speed for one minute.
Damagedwheelswillnormallybreakapartduring
this test time.
9. 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 shop apron capable of stopping
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 hear-
ing loss.
10. 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wheelmay
yawayandcauseinjurybeyondimmediatearea
of operation.
11. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den 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.
12. Position the cord clear of the spinning acces-
sory.Ifyoulosecontrol,thecordmaybecutor
snaggedandyourhandorarmmaybepulledinto
the spinning wheel.
13. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
wheelmaygrabthesurfaceandpullthepower
tool out of your control.
14. 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.
15. Regularly clean the power tool’s air vents. The
motorʼsfanwilldrawthedustinsidethehousing
and excessive accumulation of powdered metal
may cause electrical hazards.
16. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
17. 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. Pinching or snagging causes rapid
stalling of the rotating wheel which in turn causes the
uncontrolledpowertooltobeforcedinthedirection
opposite of the wheel’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.

8ENGLISH
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 line with the
rotating wheel.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,
segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade.
Suchbladescreatefrequentkickbackandlossof
control.
6. Do not “jam” the 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thepossibilityofkick-
backorwheelbreakage.
7. 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 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binding.
8. 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.
9. 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.
10. 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.
11. Before using a segmented diamond wheel,
make sure that the diamond wheel has the
peripheral gap between segments of 10 mm or
less, only with a negative rake angle.
Additional Safety Warnings:
1. Never attempt to cut with the tool held upside
down in a vise. This can lead to serious acci-
dents,becauseitisextremelydangerous.
2. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
3. Store wheels as per manufacturer recom-
mendations. Improper storage may damage the
wheels.
SAVE THESE INSTRUCTIONS.
WARNING: DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product. MISUSE or failure to follow the safety
