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-oper-
ated (corded) power tool or battery-operated (cordless) power tool.
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 operator. Position yourself
and bystanders away from the plane of the rotating
wheel. The guard helps to protect operator from broken
wheel fragments and accidental contact with wheel.
2. Use only diamond cut-o󰀨 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-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 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 appropri-
ate, wear dust mask, hearing protectors, gloves
and shop apron capable of stopping small
abrasive or workpiece fragments. The eye pro-
tection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. Hold the power tool by insulated gripping sur-
faces only, when performing an operation where
the cutting accessory may contact hidden wir-
ing. 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. Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel may grab
the surface and pull the power tool out of your control.
13. 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.
14. 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.
15. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid stall-
ing of the rotating wheel which in turn causes the uncon-
trolled 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 caus-
ing 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.

12 ENGLISH
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 o󰀨 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 work-
piece. 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 inhalation and
skin contact. Follow material supplier safety data.
3. Store wheels as per manufacturer recommenda-
tions. 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
rules stated in this instruction manual may cause
serious personal injury.
