General Power Tool Safety
The following show the symbols used for the equipment.
Be sure that you understand their meaning before use.
・ Read instruction manual.
Wear safety glasses.
Only for EU countries
Do not dispose of electric equipment
In observance of European Directive
2012/19/EU on waste electric and
implementation in accordance with
national law, electric equipment that
have reached the end of their life must
be collected separately and returned to
recycling facility.
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and
instructions 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
Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
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. Unmodified plugs and matching outlets will
reduce risk of electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Intended use
The tool is intended for grinding ferrous materials or
deburring castings.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
Power tool use and care
18. 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.
19. 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.
20. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
21. Store idle power tools out of the reach of
children 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.
22. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many
accidents are caused by poorly maintained power
23. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
24. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking 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.
25. Have your power tool serviced by a qualified
replacement parts. This will ensure that the
safety of the power tool is maintained.
26. Follow instruction for lubricating and
changing accessories.
27. Keep handles dry, clean and free from oil and
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.
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.
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.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always
Personal safety
11. 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 influence of drugs, alcohol or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
12. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
13. 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 finger on the switch or energising power
tools that have the switch on invites accidents.
14. 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.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
17. 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 dustrelated hazards.
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.
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.
10. 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.
11. 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.
12. 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.
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
motor’s 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 flammable
materials. Sparks could ignite these materials.
16. 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
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
Safety Warnings Common for Grinding Operation:
This power tool is intended to function as a
grinder. 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.
Operations such as sanding, wire brushing,
polishing or cutting-off 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.
Do not use accessories which are not
specifically designed and recommended by
the tool manufacturer. Just because the
accessory can be attached to your power tool, it
does not assure safe operation.
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.
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
Threaded mounting of accessories must
match the grinder spindle thread. For
accessories mounted by flanges, the arbour
hole of the accessory must fit the locating
diameter of the flange. 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.
Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks. 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.
Depending on application, use face shield,
safety goggles or safety glasses. As
appropriate, wear dust mask, hearing
Flanges for cut-off wheels may be different from
grinding wheel flanges.
f) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller
tool and may burst.
Additional Safety Warnings:
17. Be careful not to damage the spindle, the
flange (especially the installing surface) or the
lock nut. Damage to these parts could result
in wheel breakage.
18. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
19. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
20. Use the specified surface of the wheel to
perform the grinding.
21. Do not leave the tool running. Operate the tool
only when hand-held.
22. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
23. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
24. Use only flanges specified for this tool.
25. Check that the workpiece is properly
26. Pay attention that the wheel continues to
rotate after the tool is switched off.
27. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure
operator safety.
28. Do not use the tool on any materials
containing asbestos.
29. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
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.
a) Maintain a firm 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
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
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 or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
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 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.
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.
