SAFETY WARNINGS COMMON FOR
GRINDING OR ABRASIVE CUTTING-
OFF OPERATIONS
a) This power tool is intended to function as a
grinder or cut-offtool. Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool.
Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
b) Operations such as sanding, wire brushing,
polishing or hole cutting are not recommended to
be performed with this power tool.
Operations for which the power tool was not designed
may create a hazard and cause personal injury.
c) Do not convert this power tool to operate in a way
which is not specifically designed and specified by
the tool manufacturer.
Such a conversion may result in a loss of control and
cause serious personal injury.
d) Do not use accessories which are not specifically
designed and specified by the tool manufacturer.
Just because the accessory can be attached to your
power tool, it does not ensure safe operation.
e) 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 fly apart.
f) 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.
g) The dimensions of the accessory mounting must
fit the dimensions of the mounting hardware of the
power tool.
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.
h) 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 accessory 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 accessories will normally break apart during
this test time.
i) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments.
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask
or respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
j) 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
fly away and cause injury beyond immediate area of
operation.
k) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden 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.
l) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
accessory.
m) Never lay the power tool down until the accessory
has come to a complete stop.
The spinning accessory may grab the surface and pull
the power tool out of your control.
n) 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.
o) 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.
p) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
q) 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 accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled 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 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.
00BookG13BYEQ2AUST.indb600BookG13BYEQ2AUST.indb6 2022/06/1611:45:532022/06/1611:45:53

7
a) Maintain a firm grip with both hands 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 kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) 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.
d) 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.
e) 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.
SAFETY WARNINGS SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-
OFF OPERATIONS
a) Use only wheel types that are specified for your
power tool and the specific guard designed for the
selected wheel.
Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
b) 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.
c) 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, accidental contact with wheel and
sparks that could ignite clothing.
d) Wheels must be used only for specified applications.
For example: do not grind with the side of cut-off
wheel.
Abrasive cut-offwheels are intended for peripheral
grinding, side forces applied to these wheels may cause
them to shatter.
e) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
f) Do not use worn down wheels from larger power
tools.
A wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
g) When using dual purpose wheels always use the
correct guard for the application being performed.
Failure to use the correct guard may not provide the
desired level of guarding, which could lead to serious
injury.
ADDITIONAL SAFETY WARNINGS
SPECIFIC FOR ABRASIVE CUTTING-
OFF OPERATIONS
a) Do not “jam” the cut-offwheel 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 kickback or wheel breakage.
b) 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 spinning wheel and the power tool directly at you.
c) When the wheel is binding or when interrupting
a cut for any reason, switch offthe power tool
and hold it motionless until the wheel comes to a
complete stop. Never attempt to remove the cut-
offwheel 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.
d) 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.
e) Support panels or 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 workpiece on both
sides of the wheel.
f) Use extra caution making a “pocket cut” into
existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
g) Do not attempt to do curved cutting.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage, which
can lead to serious injury.
GENERAL SAFETY INSTRUCTIONS
FOR GRINDERS
– Attach the side handle firmly, hold the housing and the
side handle with both hands, and support the tool body
securely. (Fig. 2)
– Check that speed marked on the wheel is equal to or
greater than the rated speed of the grinder;
– Ensure that the wheel dimensions are compatible with
the grinder;
– Inspect the grinding wheel before use, do not use
chipped, cracked or otherwise defective products;
– Ensure that mounted wheels and points are fitted in
accordance with the manufacturer’s instructions;
– Ensure that blotters are used when they are provided
with the bonded abrasive product and when they are
required;
– Ensure that the abrasive product is correctly mounted
and tightened before use and run the tool at no-load for
30 seconds in a safe position, stop immediately if there
is considerable vibration or if other defects are detected.
If this condition occurs, check the machine to determine
the cause;
– If a guard is equipped with the tool never use the tool
without such a guard;
00BookG13BYEQ2AUST.indb700BookG13BYEQ2AUST.indb7 2022/06/1611:45:532022/06/1611:45:53

– Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels;
– For tools intended to be fitted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length;
– Do not use cutting offwheel for side grinding;
– Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite flammable
substances;
– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, first disconnect the tool from
the mains supply (use non metallic objects) and avoid
damaging internal parts;
– Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves, helmet
and apron should be worn;
– Pay attention to the wheel that continues to rotate after
the tool is switched off.
– When using dual-purpose (combined grinding and
cut-offwheels), use only the type A wheel guard (See
page 12)
– When using a type A wheel guard for lateral grinding,
the guard may interfere with the workpiece causing poor
control.
– When using a type B wheel guard for cutting-off
operations with bonded cut-offwheels, there is an
increased risk of exposure to emitted sparks and
particles, as well as exposure to wheel fragments in the
event of a wheel burst.
– When using a type A, B wheel guard for cutting-off
operations or lateral grinding in concrete or masonry,
there is an increased risk of exposure to dust and loss of
control resulting in kickback.
– Do not use any segmented diamond cut-offwheels with
segment slits >10 mm. Only negative segment cutting
angles are permitted.
– The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must be
sufficiently supported.
– Observe the specifications of the tool or accessory
manufacturer. Protect wheels from grease or impact.
– Accessories must be stored and handled with care in
accordance with the manufacturer's instructions.
WARNING
– When using a cutting-offwheel, be sure to attach a type
A wheel guard.
– When using a grinding wheel, be sure to attach a type B
wheel guard.
– For safety reasons, only use the wheel guard provided
for the respective accessory. Using an incorrect wheel
guard can lead to loss of control and serious injuries.

Also ensure that the depressed center wheel is properly
mounted and the wheel nut is securely tightened.
5. Confirm that the push button is disengaged by pushing
push button two or three times before switching the
power tool on.
6. To prolong the life of the machine and ensure a first
class finish, it is important that the machine should not
be overloaded by applying too much pressure. In most
applications, the weight of the machine alone is sufficient
for effective grinding. Too much pressure will result in
reduced rotational speed, inferior surface finish, and
overloading which could reduce the life of the machine.
7. The wheel continues to rotate after the tool is switched
off.
After switching offthe machine, do not put it down until
the depressed center wheel has come to a complete
stop. Apart from avoiding serious accidents, this
precaution will reduce the amount of dust and swarf
sucked into the machine.
8. When the machine is not use, the power source should
be disconnected.
9. Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident
before the depressed center wheel is assembling and
disassembling.
10. Caution when using near welding equipment
When using the grinder in the immediate vicinity of
welding equipment, the rotational speed may become
unstable. Do not use the grinder near welding equipment.
11. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.
12. Be careful of brake kickback.
This disc grinder features an electric brake that functions
when the switch is released. As there is some kickback
when the brake functions, be sure to hold the main body
securely.
13. Do not operate from a direct current power source,
booster or any other type of transformer. Doing so may
not only cause damage to the grinder, but may lead to
accidents.

the eyes to debris or dust.
After use, remove any debris or dust adhered to the filter
using a soft brush. (Fig. 11) Check the filter periodically
to ensure that it is free of scratching, chipping, or tearing.
Replace with a new filter if the filter is damaged in any way.
NOTE
If the mesh is clogged and the debris or dust cannot be
removed, detach the filter and clean it with an air gun,
etc. (See “Exchanging the filter set (Fig. 12)”)
5. Exchanging the filter set (Fig. 12)
NOTE
○When detaching the filter, be careful not to let debris
enter the tool body.
○Leave the filter set attached to the body, except when
cleaning or exchanging the filter set.
6. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool.
Exercise due care to ensure the winding does not become
damaged and/or wet with oil or water.
NOTE
In order to expel debris and dust, periodically run the
motor with no load.
7. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
8. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
