Protection class
The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted sound pressure level of the product
is 80 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).

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.

Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
/II
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
External Dust Extraction (see figure A)
Attach a vacuum hose 8 onto the outlet piece 3. Connect the
vacuum hose 8 with a vacuum cleaner. An overview for con-
necting to various vacuum cleaners can be found at the begin-
ning of these operating instructions.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
