Protection class
The values given are valid for a nominal voltage [U] of 230 V. For different 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 75 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.

Assembly
 Before any work on the machine itself, pull the mains
plug.
Replacing the Sanding Sheet (see figure A)
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 8, e. g., with a brush.
The surface of the sanding plate 8 is fitted with Velcro backing
for quick and easy fastening of sanding sheets with Velcro ad-
hesion.
Press the sanding sheet 10 firmly against the bottom side of
the sanding plate 8.
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.
Application
For sanding off paint
For sanding primer (e. g., for removing brush dashes,
drops of paint and paint run)
For final sanding of primers before coating
