GENERAL SAFETY INSTRUCTIONS FOR POW-
ER TOOLS
WARNING! All safety instructions, user man-
uals, images and regulations supplied with
these tools must be read. Failure to follow all
of the following instructions may result in elec-
tric shock, fire, and/or serious personal injury.
All instructions and the user manual must be
kept for future reference.
Safety of working environment
1. The workplace must be kept clean and well lit.
Untidy and dark spaces are often the cause of
accidents.
2. Power tools must not be used in potentially ex-
plosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools
create sparks that can ignite dust or fumes.
3. Children and other persons must be kept away
when using power tools. If the operator is dis-
turbed, he/she may lose control of the opera-
tion.
Electrical safety
1. The plug on the power tool's flexible lead must
match the power outlet. The plug must never
be modified in any way. No socket adapters
may be used with tools that have a protective
earth connection. Plugs and respective sockets
that are rendered unusable will reduce the risk
of electric shock.
2. The operator must not touch grounded ob-
jects, such as pipes, central heating units,
cookers and refrigerators. The risk of electric
shock is greater if your body is connected to
the ground.
3. Power tools must not be exposed to rain, mois-
ture or wetness. If water enters the power tool,
the risk of electric shock increases.
4. The flexible supply must not be used for oth-
er purposes. The power tool must not be car-
ried or pulled by the cord, nor must the plug
be unplugged from the socket. The inlet must
be protected from heat, grease, sharp edges
or moving parts. Damaged or tangled leads
increase the risk of electric shock.
5. If the power tool is used outdoors, an extension
cord suitable for outdoor use must be used. Us-
ing an extension cord for outdoor use reduces
the risk of electric shock.
6. If the power tool is used in a humid environ-

5ENGLISH
ment, a residual current device (RCD) must be
used. Using an RCD reduces the risk of electric
shock.
Safety of persons
1. When using a power tool, the operator must be
careful, pay attention to what he/she is doing,
and concentrate and think clearly. Power tools
must not be used if the operator is tired or un-
der the influence of drugs, alcohol or medica-
tion. Momentary inattention while using a pow-
er tool can result in serious personal injury.
2. Use personal protective equipment. Always
use eye protection. Protective equipment such
as a respirator, non-slip safety shoes, hard hat
and hearing protection, used in accordance
with the working conditions, reduces the risk of
personal injury.
3. Unintentional starting of the machine must be
avoided. Make sure that the switch is in the off
position before plugging in and/or connecting
the battery pack, lifting or carrying the tool.
Carrying a tool with your finger on the switch
or plugging in a tool fork with the switch on can
cause injury.
4. All adjusting tools or wrenches must be re-
moved before turning on the tool. An adjusting
tool or wrench that remains attached to the ro-
tating part of the power tool may result in per-
sonal injury.
5. The operator must only work where he/she can
safely reach. The operator must always main-
tain a stable posture and balance. This will al-
low better control of the power tool in unfore-
seen situations.
6. Dress appropriately. Do not wear loose cloth-
ing or jewellery. The operator must make sure
that his/her hair and clothing are a sufficient
distance away from moving parts. Loose cloth-
ing, jewellery and long hair can be caught in
moving parts.
7. Where equipment is provided for connecting
dust extraction and collection facilities, care
must be taken to ensure that it is connected
and used correctly. The use of such equipment
can reduce hazards caused by dust.
8. The operator must not allow the routine that
results from the frequent use of the tools, to
cause them to become complacent and ignore
the principles of tool safety. Careless activity
can cause serious injuries in a split second.
Use and the maintenance of power tools
1. Power tools must not be overloaded. It is es-
sential to use the correct power tool for the
work being carried out. The correct power tool
will do the work it was designed to do better
and safer.
2. Power tools that cannot be turned on and off
with the switch must not be used. Any power
tool that cannot be operated with the switch is
dangerous and must be repaired.
3. Before making any adjustments, changing ac-
cessories, or storing power tools, unplug the
power tool and/or remove the battery pack
from the power tool if it is removable. These
precautions reduce the risk of accidentally
starting the power tool.
4. Unused power tools must be stored out of
the reach of children. Persons unfamiliar with
the power tool or these instructions must not
be allowed to use the power tool. Power tools
are dangerous in the hands of inexperienced
users.
5. Power tools and accessories must be main-
tained. The adjustment of moving parts and
their mobility must be checked and attention
focused on cracks, broken parts and any other
circumstances that may jeopardize the func-
tion of the power tool. If the tool is damaged,
it must be repaired before use. Many accidents
are caused by poorly maintained power tools.
6. Cutting tools must be kept sharp and clean.
Properly maintained and sharpened cutting
tools are less likely to catch on material or jam
and are easier to control.
7. Power tools, accessories and tool bits etc. must
be used in accordance with these instructions
and in the manner intended for the particular
power tool, taking into account the working
conditions and the work to be carried out. Us-
ing power tools for activities other than those
for which they are designed can lead to dan-
gerous situations.
8. Handles and grip surfaces must be kept dry,
clean and free of grease. Slippery handles and
gripping surfaces mean the tool cannot be
held and controlled in unexpected situations.
Service
1. Power tool repairs must be carried out by qual-
ified personnel using identical spare parts. This
will ensure the same level of safety of the pow-

SAFETY INSTRUCTIONS COMMON TO GRIND-
ING, SURFACE GRINDING, WIRE BRUSHING,
POLISHING OR ABRASIVE CUTTING WORK.
1. This electromechanical tool is intended for use
as a grinder, surface grinder, wire brush grind-
er, polisher or cutting tool. All safety warnings,
instructions, illustrations and specifications
given for this electromechanical tool must be
read. Failure to follow all instructions below
may result in electric shock, fire and/or serious
injury.
2. It is not recommended to carry out work such
as grinding, surface grinding, wire grinding,
polishing or cutting with this tool. Performing
work for which this tool is not intended can cre-
ate risk and cause personal injury.
3. Accessories that are not specifically designed
and recommended by the tool manufacturer
must not be used. Just because an accessory
can be attached to your tool does not guaran-
tee its safe operation.
4. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the tool. Accessories that operate at speeds
higher than their rated speed may break and
fall apart.
5. The outer diameter and thickness of the acces-
sories must be within the nominal range for the
electromechanical tool. Accessories with the
wrong size cannot be adequately protected or
controlled.
6. The clamping dimensions of discs, flanges,
washers and other accessories must be suita-
ble for mounting on the tool spindle. Accesso-
ries with clamping holes that do not match the
mounting dimensions of the power tool will be
unbalanced, may vibrate excessively and may
cause loss of control.
7. Damaged accessories must not be used
Check accessories before each use: chips and
cracks on grinding wheels, tears or excessive
wear on backing pads, loose or broken wires
on wire brushes. If the accessory or tool has
been dropped, check for damage or reinstall
undamaged accessories. After checking and
fitting the attachment, the operator and any by-
standers must be positioned out of the plane
of the rotating attachment and the tool should
be allowed to idle at maximum speed for one
minute. During this test period, damaged ac-
cessories will usually break or disintegrate.
8. Personal protective equipment must be used.
Depending on the application, a face shield
or safety goggles must be worn. A dust mask,
hearing protection, gloves and an apron capa-
ble of retaining small fragments of abrasions or
workpieces must be used to the appropriate
extent. Eye protection must be able to retain
flying debris that arises during various work
activities. The dust mask or respirator must be
able to filter out the particles that form during
the activity. Prolonged exposure to high-inten-
sity noise can cause hearing loss.
9. Any bystander must remain at a safe distance
from the work area. Everyone entering the work
area must use personal protective equipment.
Fragments of the workpiece or damaged ac-
cessories can fly off and cause injuries even
outside the immediate work area.
10.When performing an operation where the cut-
ting tool may come into contact with a hidden
guide or its own power supply, the power tool
must be held only by the insulated gripping
surfaces. Contact of a cutting tool with a "live"
wire can cause uninsulated metal parts of the
power tool to become "live" and cause an elec-
tric shock to the user
11.The flexible feed must be located out of reach
of the rotating tool. If the operator loses con-
trol, the moving feed may be cut or reground,
and the operator's hand or arms may be pulled
into the rotating tool.
12.Electromechanical tools must never be stored
until the tool has come to a complete stop. The
rotating tool can catch on the surface and pull
the tool out of the operator's control.
13.Electromechanical tools must never be started
when being carried by the operator. The rotat-
ing tool can get caught on the operator’s cloth-
ing and be pulled against the body.
14.The air vents on the tool must be regularly
cleaned. The motor fan draws dust into the
cabinet, and excessive accumulation of metal
dust can cause electrical hazards.
15.Electromechanical tools must not be used
near flammable materials. These materials
could ignite from sparks.
16.Accessories requiring cooling by liquid must
not be used. The use of water or other coolants

can cause electric shock or death.
ADDITIONAL SAFETY INSTRUCTIONS FOR ALL
WORK ACTIVITIES
Recoil and related warnings
•Recoil is a sudden reaction to the gripping or
jamming of a rotating disc, backing pad, brush
or other accessories. Clamping or jamming will
cause the rotating tool to abruptly stop, which
in turn will cause the uncontrolled tool to move
in the opposite direction to the rotation of the
tool at the point of jamming.
•For example, if a grinding disc is clamped or
jammed in the workpiece, the edge of the disc
that enters the clamping point can be pushed
away from the surface of the material, causing
the disc to be pushed up or thrown off. The disc
can either jump towards or away from the op-
erator, depending on the direction of the blade
at the point of jamming. The grinding disc can
also break in these cases.
•The recoil is the result of the improper use of
the power tool and/or incorrect working proce-
dures or conditions and can be prevented by
proper compliance with the safety precautions
described below.
1. The tool must be held firmly and the correct
body and arm position must be maintained so
that it can withstand the forces of the recoil. An
auxiliary handle, if equipped, must always be
used for maximum control of the recoil or re-
action torque when starting the machine. The
operator is able to check the reaction torques
and kickback forces if the correct safety precau-
tions are observed.
2. The hand must never come close to the rotat-
ing tool.The tool can throw the operator's hand
back.
3. Do not stand in the area where the tool can
reach in the event of recoil. The recoil throws
the tool in the opposite direction to the direc-
tion of the movement of the blade at the point
of jamming.
4. Special attention must be paid to machining
corners, sharp edges, etc. Jumping and jam-
ming of the tool must be avoided. Corners,
sharp edges or jumping tend to jam the rotat-
ing tool and cause loss of control or recoil.
5. A chain saw or toothed saw blade must not be
attached to the tool. These discs often cause
recoil and loss of control.
SAFETY WARNINGS SPECIFIC TO GRINDING
WORK ACTIVITIES:
1. Only use the types of discs recommended for
this electromechanical tool and the specific
guard designed for the selected disc. Discs for
which the power tool has not been designed
cannot be adequately covered and are danger-
ous.
2. The protective cover must be securely attached
to the power tool and positioned for maximum
safety so that as little of the blade as possible is
exposed in the direction of operation. The pro-
tective cover helps protect the operator from
blade debris, accidental contact with the disc
and sparks that can ignite clothing.
3. The discs must only be used as recommend-
ed. For example: grinding with the side of the
cutting disc is forbidden. Abrasive cutting discs
are designed for circumferential cutting; the
lateral forces acting on these discs could shat-
ter them.
4. Undamaged disc flanges that are the correct
size and shape for the selected disc must al-
ways be used. Proper blade flanges support
the blade, reducing the possibility of the blade
breaking. Cutting wheel flanges may differ
from grinding wheel flanges.
5. Worn discs of originally larger dimensions,
which are intended for larger electromechan-
ical tools, must not be used. discs designed for
larger electromechanical tools are not suitable
for the higher speeds of smaller tools and may
break.
SAFETY WARNINGS SPECIFIC TO ABRASIVE
CUTTING WORK:
1. The cutting disc must not strike the material or
be subjected to excessive pressure. No attempt
should be made at an excessive depth of the
cut. Overloading the blade increases the load
and the susceptibility to twisting or jamming of
the blade in the cut and the possibility of recoil
or cracking the blade.
2. Do not stand in a straight line with or behind
the rotating disc. Once the blade moves away
from the operator's body at the point of oper-
ation, a possible recoil can throw the rotating
discs and electromechanical tools directly at
SAFETY INSTRUCTIONS

8ENGLISH
the operator.
3. If the disc jams or cutting is interrupted for any
reason, the power tool must be turned off and
held stationary until the blade comes to a com-
plete stop. The operator must never attempt to
remove the cutting blade from the cut while the
blade is in motion as recoil may occur. The situ-
ation must be investigated and a remedy found
to avoid jamming the disc.
4. Cutting of the workpiece must not be restarted.
The blade is allowed to reach full speed and is
carefully re-inserted into the cut. If the tool is
restarted with the blade in the cut, it may jam,
be pushed up or recoil.
5. Panels and other large pieces of workpieces
must be supported to reduce the risk of wheel
and recoil jams. Large workpieces tend to sag
under their own weight. Supports must be
placed under the workpiece near the cutting
line and near the edges of the workpiece on
both sides of the blade.
Special care must be taken when making "pulp
cuts" into existing walls or other blind spaces.
The penetrating blade can cut through gas or wa-
ter pipes, power lines, or objects that can cause
recoil.SAFETY WARNINGS SPECIFIC TO SUR-
FACE GRINDING WORK:
•Do not use oversized sandpaper for the grind-
ing disc. The manufacturer's recommendations
must be followed when selecting sandpaper.
Large sandpaper that extends beyond the
sanding plate poses a risk of tearing and can
cause jams, wheel tearing or recoil.
SAFETY WARNINGS SPECIFIC TO POLISHING
WORK:
•Do not let any loose part of the polishing
sleeve or its fastening laces rotate freely. All
loose fastening laces should be filed or cut off.
Loose and rotating fastening laces can become
tangled in the operator's fingers or jam on the
workpiece.
SAFETY WARNINGS SPECIFIC TO WIRE BRUSH
GRINDING WORK:
•Even during normal operation, wire bristles are
shed from the brush. Wires must not be over-
loaded by excessive brush loading. Wire bris-
tles can easily penetrate light clothing and/or
leather.
• If the use of a protective cover is recommend-
ed for wire brush grinding, secure it so that
there is no contact between the wire disc or
brush and the protective cover.The wire disc or
brush can increase its diameter when working
due to loads and centrifugal forces.
