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 exposure.
The declared vibration emission level represents the main
applications 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 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 significantly 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
patterns.
Assembly
u Before any work on the machine itself, pull the
mains plug.
Replacing the Sanding Sheet
When attaching a new sanding sheet, remove any dust or
debris from the sanding plate 2 (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.
Sanding Sheets with Velcro Backing
The sanding plate 2 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 2 from any debris by tapping
against it in order to enable optimum adhesion.
Position the sanding sheet 4 flush alongside one edge of the
sanding plate 2, then lay the sanding sheet onto the sanding
plate and press firmly.
To remove the sanding sheet 4, grasp it at one of the tips
and pull it off from the sanding plate 2.
Sanding Sheets without Velcro Backing (see figure A– C)
n Press the release button 5 and keep it depressed.
o Guide the sanding sheet 4 to the stop under the opened
front clamping bracket 6 and let go of the release
button 5 again. Pay attention that the sanding sheet is
clamped centrally.
p Press the sanding sheet clamp 3 inward and pivot it to
the stop.
q Fold the sanding sheet 4 firmly around the sanding
plate. Guide the other end of the sanding sheet 4
between the rear clamping bracket and the red roller on
the clamping bracket 3.

r Hold the sanding sheet tensely and press the clamping
bracket 3 toward the sanding plate to lock the sanding
sheet.
Sanding sheets without holes, e. g. from rolls or by the
meter, can be punctured with the perforating tool 14. For
this, push the power tool with the sanding sheet mounted
onto the perforating tool (see figure F).
To remove the sanding sheet 4, loosen the clamping bracket
3 and pull out the sanding sheet from the rear holding
fixture. Press the release button 5 and completely remove
the sanding sheet.
Selecting the Sanding Sheet
Depending on the material to be worked and the required
rate of material removal, different sanding sheets are
available:
For the working of all
wooden materials
For coarse-sanding, e. g.
of rough, unplaned
beams and boards
For face sanding and
planing small
irregularities
For finish and fine
sanding of hard woods
For the working of
paint/enamel coats or
primers and fillers
For sanding off paint
For sanding primer
For final sanding of
primers before coating
Dust/Chip Extraction
u 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 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-treatment additives
(chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system
suitable for the material.
