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.
Cut-off machine safety warnings
1. Position yourself and bystanders away from
the plane of the rotating wheel. The guard helps
toprotecttheoperatorfrombrokenwheelfrag-
ments and accidental contact with wheel.
2.
Use only bonded reinforced 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 a 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 the
power tool or wheel is dropped, inspect for dam-
age or install an undamaged wheel. After inspect-
ing and installing the wheel, position yourself
and bystanders away from the plane of the rotat-
ing 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 hearing 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. 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.
12. Regularly clean the power tool’s air vents. The
motor’s fan can draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
13. Do not operate the power tool near ammable
materials. Do not operate the power tool while
placed on a combustible surface such as
wood. Sparks could ignite these materials.
14. 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
cuttingunittobeforcedupwardstowardtheoperator.
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 mate-
rialcausingthewheeltoclimboutorkickout.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 posi-
tion your body and arm to allow you to resist
kickback forces. The operator can control upward
kickbackforces,ifproperprecautionsaretaken.
2. Do not position your body in line with the
rotating wheel.Ifkickbackoccurs,itwillpropel
the cutting unit upwards toward the operator.
3. 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.

8ENGLISH
4. 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.
5. When the wheel is binding or when interrupt-
ing a cut for any reason, switch off the power
tool and hold the cutting unit 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.
6. 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.
7. Support 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 work-
pieceonbothsidesofthewheel.
Additional safety warnings
1. Watch out for ying sparks when operating.
Theycancauseinjuryorignitecombustible
materials.
2. Secure work. Use clamps or a vise to hold
work when practical. It's safer than using your
handanditfreesbothhandstooperatetool.
3. Secure the cut-off wheel carefully.
4. Be careful not to damage the spindle, anges
(especially the installing surface) or bolt, or
the cut-off wheel itself might break.
5. Keep guards in place and in working order.
6. Hold the handle rmly.
7. Keep hands away from rotating parts.
8. Make sure the cut-off wheel is not contacting
the work-piece before the switch is turned on.
9. Before each use, watch for utter or excessive
vibration that might be caused by poor instal-
lation or a poorly balanced wheel.
10. Remove material or debris from the area
that might be ignited by sparks. Be sure that
others are not in the path of the sparks. Keep
a proper, charged re extinguisher closely
available.
11. If the cut-off wheel stops during the opera-
tion, makes an odd noise or begins to vibrate,
switch off the tool immediately.
12. Always switch off and wait for the cut-off
wheel to come to a complete stop before
removing, securing workpiece, working vise,
changing work position, angle or the cut-off
wheel itself.
13. Do not touch the workpiece immediately after
operation; it is extremely hot and could burn
your skin.
14. Store wheels in a dry location only.
SAVE THESE INSTRUCTIONS.
