3. Keep children and bystanders away while
operating a power tool. Distractions can cause
youtolosecontrol.
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. Unmodiedplugsandmatchingoutletswill
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-
tricshockifyourbodyisearthedorgrounded.
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.

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.

ing accessories.
Cordless 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 bonded reinforced or diamond cut-o
wheels for your power tool. Just because an
accessorycanbeattachedtoyourpowertool,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
theirratedspeedcanbreakandyapart.
4.
Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-o wheel.Abrasivecut-owheelsare
intended for peripheral grinding, side forces applied
tothesewheelsmaycausethemtoshatter.
5. Always use undamaged wheel anges that are
of correct diameter for your selected wheel.
Properwheelangessupportthewheelthus
reducingthepossibilityofwheelbreakage.
6. Do not use worn down reinforced wheels from
larger power tools. Wheels intended for a larger
power tool are not suitable for the higher speed of
asmallertoolandmayburst.
7. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool.Incorrectlysizedaccessories
cannotbeadequatelyguardedorcontrolled.
8.
The arbour size of wheels and anges must prop-
erly t the spindle of the power tool. Wheels and
angeswitharbourholesthatdonotmatchthemount-
ing hardware of the power tool will run out of balance,
vibrateexcessivelyandmaycauselossofcontrol.
9.
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
normallybreakapartduringthistesttime.
10.
Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments.

13. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
wheelmaygrabthesurfaceandpullthepower
tooloutofyourcontrol.
14. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessorycouldsnagyourclothing,pullingthe
accessoryintoyourbody.
15. 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
maycauseelectricalhazards.
16. 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 stalling
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
pinchedbytheworkpiece,theedgeofthewheelthatis
entering into the pinch point can dig into the surface of
the material causing the wheel to climb out or kick out.
Thewheelmayeitherjumptowardorawayfromthe
operator, depending on direction of the wheel’s move-
mentatthepointofpinching.Abrasivewheelsmayalso
break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoidedbytakingproperprecautionsasgivenbelow.
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.Accessorymaykickbackoveryourhand.
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
haveatendencytosnagtherotatingaccessory
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
theloadingandsusceptibilitytotwistingorbinding
ofthewheelinthecutandthepossibilityofkick-
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
workpiece. Let the wheel reach full speed and
carefully re-enter the cut.Thewheelmaybind,
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
protrudingwheelmaycutgasorwaterpipes,elec-
tricalwiringorobjectsthatcancausekickback.
Additional Safety Warnings:
1. 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.
2. 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.
3. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
4. Store wheels as per manufacturer recommen-
dations. Improper storage may damage the
wheels.
5. Always use the wheel suitable for your work
and the material to be cut.
6. Examine the material to be cut before cutting.

substances,itmaycauseanexplosionorre.
7. Do not switch on the tool if a foreign object
is jammed between the guard and the wheel.
Inthiscase,uninstallthebatterycartridgeand
removetheforeignobject.
8. Use clamps or similar to support the work-
piece whenever possible.
9. Always wear hearing protection during
operation.
10. Do not cut wood materials with this tool.
11. The outside diameter and the thickness of the
wheel must be within the capacity rating of
your power tool.Incorrectlysizedwheelscannot
beadequatelyguardedorcontrolled.
12. When operating the power tool, maintain a rm
grip with both hands on the power tool and
position your body and arm to allow you to
resist kickback forces.
13. Keep your hands or face away from the rotat-
ing wheel.
14. Adjust the wheel cover to a position suitable
for your work.
