clothing and helmet.
Before using the angle grinder, install the side
handle (5) and always keep both hands on the
tool at all times during use.
transfer of electrical energy onto the machine
housing. This can mean a temporary danger of
electric shocks. This is why it is necessary when
the machine is running to blow compressed air
through the rear ventilation slots of the machine
regularly, frequently and thoroughly. Here, the
machine must be held firmly.
It is recommended to use a stationary extraction
system and to place a ground fault circuit
interrupter (GFCI) downstream.
If the angle grinder is deactivated by the GFCI
circuit interrupter, the angle grinder must be
checked and cleaned. Cleaning the motor, see
Maintenance.
The dust generated during operation is often
injurious to health (e.g. when processing oak and
beech woods, stone or paintwork which may
contain lead or other harmful materials). This dust
must not be allowed to penetrate the body. Use
dust-extraction equipment as well as wearing a
suitable dust mask.
Remove any accumulations of dust thoroughly,
using a suitable vacuum cleaner.
Dust can be explosive!
Materials which generate hazardous dusts or
vapours during processing (e.g. asbestos) should
not be used.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel
and are not able to ignite inflammable
substances. Endangered areas must be protected
with flame-resistant covers. Make sure that firerisk areas are always provided with suitable fire
extinguishers.
Ensure that the accessories used always fulfil
the following minimum requirements.
22
The permitted speed n
correspond at least to the
no-load speed for the power
tool (please see Technical
Specifications).
During machining, of metals
in particular, conductive dust
can form deposits inside the
machine. This can lead to the
Carry out a test run after every tool change,
ensuring that you are holding the angle grinder
firmly with both hands.
Hold the angle grinder away from your body.
Ensure that there is no-one present in the area at
risk. Run the angle grinder for approximately
30 seconds.
The angle grinder runs on for approx. 5 seconds
after switch-off.
Observe the information and instructions provided
by the tool or accessory manufacturer.
Do not contaminate discs with grease or subject
them to impact.
Damaged, eccentric or vibrating tools should not
be used.
Never use cutting discs for grinding purposes.
Cutting discs must not be subjected to any lateral
pressure. During cutting or grinding operation,
always work with the wheel guard (4) fitted.
Use tools in dry operating conditions only.
Do not attempt to touch the moving tool - risk of
injury.
Ensure that no damage is caused to gas or water
pipes, electrical cables and weight-bearing walls
(statics).
When using the power tool outdoors, an FI safety
switch with a maximum tripping current of 30 mA
Respect the maximum
grinding-disc diameter (please
see Technical Specifications).
The diameter of the central
hole in the grinding disc (3)
must fit the inner flange (10)

any adapters or reducers.
must be connected on the incoming line side.
Angle grinder in continuous operation: To avoid
the possibility of unintentional start-up: always
turn off the switch when the plug is removed from
the socket or if an interruption to the power supply
has occurred.
Use elastic cushioning layers, if they are provided
with the coated abrasive and if they are called for.

must
Page 23
Hold the work piece securely in place.
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.
Abrasive wheels shall be stored and handled with
care in accordance with manufacturer`s
instructions.
If operating the power tool in damp locations is
unavoidable, a Ground Fault Circuit Interrupter
must be used to supply the power to your tool.
Electrician’s rubber gloves and footwear will
further enhance your personal safety.
When using grinding wheel attachments, the
guard must always be attached to the tool and
positioned for maximum safety, so the least
amount of wheel is exposed from the side the tool
is being operated.
Grinding wheels or any other accessory must
have a maximum safe operation speed greater
than the “no load RPM” marked on the tool´s
nameplate.
Always use auxiliary handle for maximum
control over torque reaction or kick-back.
Operation of the grinder without the side handle
could cause loss of control of the grinder,
resulting in possible serious personal injury.
Before using a grinder or installing a new
wheel, inspect the grinding wheel for chips
and cracks. Remove bad wheels immediately.
Run the tool at no load for one minute,
holding the tool in the direction away from
people. Wheels with flaws will normaly break
apart during this time.
Carefully handle both the tool and individual
grinding wheels to avoid chipping or cracking.
Install a new wheel if tool is dropped while
grinding. Do not use a wheel that may be
damaged. Fragments from a wheel that bursts
during operation will fly away at great velocity
possibly striking you or bystanders.
Warning! Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
– Lead from lead-based paints,
– Crystalline silica from bricks and cement and
other masonry products, and
– Arsenic and cromium from chemically treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as dust masks that are specially
designed to filter out microscopic particles.
Read operation instructions
Wear safety goggles
If the safety clutch is tripped, switch the angle
grinder off immediately and remedy the fault.
A damaged or cracked side handle must be
replaced. Never operate a machine with a
defective side handle.

15 Environmental Protection
Metabo packaging is 100% suitable for recycling.
Power tools and accessories at the end of their
service life still contain large amounts of valuable
raw materials and plastics which can likewise be
fed back into a recycling process.
As the dust generated during grinding/cutting may
contain harmful materials, do not dispose of it
along with domestic waste but ensure it is taken
to a collection point for special waste for proper
disposal.
These Operating Instructions are printed on paper
produced in a chlorine-free bleaching process.
