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.
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 conjunc-tion with additives for wood
conditioning (chro-mate, wood preservative).
Material containing asbestos must only be treated
by specialists.
- Where the use of a dust extraction device is
possible it shall be used.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is
recommended.
Follow national requirements for the materials
you want to work with.
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 fire-
risk areas are always provided with suitable fire
extinguishers.
Ensure that the accessories used always fulfil
the following minimum requirements

During machining, of metals
in particular, conductive dust
can form deposits inside the
machine. This can lead to the
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)
without any play. Do not use
any adapters or reducers.

The permitted speed n
must correspond at least to
the no-load speed for the
power tool (please see
Technical Specifications).
Use at least "max. 45 m/s".
max. 80 mm
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
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.
If using thread hole discs, ensure that the thread
in the disc is long enough for the spindle.
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
