The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.

Remove dirt and dust from the sanding plate (10), e.g. with
a brush, before attaching a new sanding sheet.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.
Sanding sheets with hook-and-loop backing
(see figure E)
The sanding plate (10) is fitted with a hook-and-loop fasten-
ing, allowing sanding sheets with a similar backing to be se-
cured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (10)
before fitting the sanding sheet (14) to facilitate maximum
adhesion.
Position the sanding sheet (14) so that it is flush with one
side of the sanding plate (10), then place the sanding sheet
on the sanding plate and press it on firmly.
To remove the sanding sheet (14), take hold of it by a corner
and pull it away from the sanding plate (10).

Push the clamping lever (9) down.
Slide the sanding sheet (14) under the open front clamping
bracket (8) as far as possible and let go of the clamping lever
(9).
Open the clamping lever (11).
Position the sanding sheet (14) so that it fits tightly around
the sanding plate. Slide the other end of the sanding sheet
(14) under the open front clamping bracket (12) and clamp
the sanding sheet in place by closing the clamping lever
(11).
Unperforated sanding sheets, e.g. from rolls or bulk stock
sold by the metre, can be perforated using the punch (15)
for the purpose of dust extraction. To do this, fit the sanding
sheet on the power tool and push the tool down onto the
punch (see figure D).
To remove the sanding sheet (14), open the clamping lever
(11) and push the clamping lever (9) down. Pull the sanding
sheet out.
Choosing the sanding sheet
Different sanding sheets are available, depending on the ma-
terial you are working with and the required surface removal
rate:
For processing all wood and wood-based ma-
terials
For pre-sanding, e.g. of rough and un-
even beams and boards
For surface sanding and levelling of
slight irregularities
For finish-sanding and fine sanding of
hardwoods
For processing paint and lacquer layers or
primers such as fillers and bodyfillers
For sanding down paint
For sanding undercoats
For final sanding of primers prior to
painting
