Operating Instructions
1. Specified Use
The flat head angle grinders, when fitted with original Metabo accessories, are suitable for grinding,
sanding, cutting-off and wire brushing metal,
concrete, stone and similar materials without the
use of water.
The user bears sole responsibility for any damage
caused by improper use.
Generally accepted accident prevention regulations and the enclosed safety information must be
observed.
ENGLISH en
d) 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.
e) 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.
f) 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.
2. General safety instructions
For your own protection and for the
protection of your electrical tool, pay
attention to all parts of the text that are
marked with this symbol!
WARNING – Reading the operating instructions will reduce the risk of injury.
Pass on your electrical tool only together with these
documents.
General Power Tool Safety Warnings
WARNING – Read all safety warnings and
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.
2.1 Work area safety
a) Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2.2 Electrical safety
a) 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 out-
lets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
2.3 Personal safety
a) 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.
b) 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.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f) 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 parts.
g) 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 dust-related hazards.
2.4 Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
5
ENGLISHen
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) 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.
e) 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 acci-
dents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) 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.
2.5 Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
3. Special Safety Instructions
3.1 Safety Warnings Common for Grinding,
Sanding, Wire Brushing or Abrasive Cutting-Off Operations:
Use
a) This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool. Read
all
safety warnings,
and specifications provided with this power
tool. Failure to follow all the instructions may result
in electric shock, fire and/or serious injury.
b) Operations such as polishing are not recom-
mended 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 use accessories which are not specif-
ically designed and recommended by the tool
manufacturer. Just because the accessory can be
attached to your power tool, it does not assure safe
operation.
d) 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.
e) The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized acces-
sories cannot be adequately guarded or controlled.
f) The arbour size of wheels, flanges, backing
pads or any other accessory must properly fit
6
the spindle of the power tool. Accessories with
instructions, illustrations
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.
g) Do not use a damaged accessory. Before
each use, inspect accessories such as abrasive wheels for chips and cracks, backing pad
for cracks, tear or excess wear, wire brush for
loose or cracked wires. If a power tool or
accessory is dropped, check it 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.
h) Wear personal protective equipment.
Depending on application, use a 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 filtering
particles generated by your operation. Prolonged
exposure to high intensity noise may cause hearing
loss.
i) 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.
j) Hold 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 shock the operator.
k) Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
I) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grip the surface and pull
the power tool out of your control.
m) 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.
n) 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.
o) Do not operate the power tool near flam-
mable materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
3.2 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 to the accessory’s rotation at
the point of jamming.
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.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use the 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 around
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.
3.3 Safety Warnings Specific for Grinding
and Cutting-Off Operations:
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 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 fragments, accidental
contact with the wheel and sparks which could
ignite clothing.
c) Wheels must be used only for recommended
applications.
For example: do not grind with the side of the
cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied
to these wheels may cause them to shatter.
ENGLISH en
d) 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.
e)
Do not use worn down wheels from larger
power tools. Wheels intended for larger power
tools are not suitable for the higher speed of a
smaller tool and may burst.
3.4 Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations:
a) Do not “jam” the cut-off wheel or apply
excessive pressure. Do not attempt to make
excessively deep cuts. 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) If the wheel jams or if you interrupt a cut for
any reason, switch off the power tool and hold
the power tool motionless until the wheel
comes to a complete stop. Never attempt to
remove the cut-off wheel from the cut while the
wheel is in motion, otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of the wheel jam.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may jam,
walk up or kickback if the power tool is restarted in
the workpiece.
e) Support panels or any oversized workpiece
to minimise 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 when 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.
3.5 Safety Warnings Specific for Sanding
Operations:
a) Do not use oversized sanding disc paper.
Follow manufacturer's recommendations when
selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing
of the disc or kickback.
3.6 Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are lost by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
7
ENGLISHen
b) If the use of a safety guard is recommended
for wire brushing, do not allow any interference
of the wire wheel or brush with the guard. Wire
wheel or brush may expand in diameter due to work
load and centrifugal forces.
3.7 Additional Safety Instructions
WARNING – Always wear protective
goggles.
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Grinding discs must be stored and handled with
care in accordance with the manufacturer's instructions.
Never use parting grinder discs for roughing work.
Do not apply pressure to the side of parting grinder
discs.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be supported adequately.
If accessories with threaded inserts are used, the
end of the spindle may not touch the base of the
hole on the grinding tool. Make sure that the thread
in the accessory is long enough to accommodate
the full length of the spindle. The thread in the
accessory must match the thread on the spindle.
See page 3 and chapter 13. Technical Specifications for more information on the spindle length and
thread.
Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic,
such as oak and beech dust, especially in
conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing
asbestos must only be treated by specialists.
- Use a dust extraction device where possible.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is recom-
mended.
Follow national requirements for the materials you
want to work with.
Materials that generate dusts or vapours that may
be harmful to health (e.g. asbestos) must not be
processed.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first disconnect the
power tool from the mains supply (use non-metallic
objects) and avoid damaging internal components.
Damaged, eccentric or vibrating tools must not be
used.
Avoid damage to gas or water pipes, electrical
cables and load-bearing walls (static).
