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 78 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).

The vibration 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 anoth-
er. It may be used for a preliminary assessment of exposure.
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 insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase 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
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.

Dust/Chip Extraction
kg 1.1
 Dusts from materials such as lead-containing coatings,
/II
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
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.
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.
Replacing the Sanding Sheet (see figure B)
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 5 (e. g. with a brush).
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.
The sanding plate 5 is fitted with Velcro backing for quick and
easy fastening of sanding sheets with Velcro adhesion.
Before attaching the sanding sheet 4, free the Velcro backing
of the sanding plate 5 from any debris by tapping against it in
order to enable optimum adhesion.

– As far as possible, use a dust extraction system suita-
ble for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
