Delivery Scope
Angle grinder, protection guard, auxiliary handle.
Special protection guards, application tools and other acces-
sories shown or described are not part of the standard deliv-
ery scope.
A complete overview of accessories can be found in our ac-
cessories program.
Intended Use
The machine is intended for roughing metal, stone and ceram-
ic materials and for drilling tiles.
For cutting with bonded abrasives, a special cutting guard
(accessory) must be used.
When cutting in stone, provide for sufficient dust extraction.
Together with the hand guard (accessory), the machine can
be used for brushing and grinding/sanding with elastic sand-
ing plates.
The machine is suitable only for working without water.

Noise/Vibration Information
The measured values of the machine are listed in the table on
page 222–224.
Noise and vibrational values (vector sum of three directions)
determined according to EN 60745.
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.
