The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Values can vary depending upon the product and are subject to application and environmental conditions. For further information

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 ac-
cessories or is poorly maintained, the vibration level and
noise emission value may differ. This may significantly in-
crease the vibration and noise emissions over the total work-
ing 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 accessories, 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.

Changing the sanding sheet
Remove dirt and dust from the sanding plate (3), 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 without hook-and-loop backing (see
figures A–C)
❶ Unlock both sanding-sheet clamps (4) and swivel them
downwards.
❷ Insert the sanding sheet (5) under the rear clamping
bracket (2). Ensure that the sanding sheet (5) is not too
short and that it is correctly clamped. Swivel the sand-
ing-sheet clamp (4) back into the starting position and
lock it in place.
❸ Position the sanding paper so that it fits tightly around
the sanding plate (3). Clamp the front part of the sand-
ing sheet under the front clamping bracket (6). Ensure
that the sanding sheet (5) is not too short and that it is
correctly clamped. Swivel the sanding-sheet clamp (4)
back into the starting position and lock it in place.
To remove the sanding sheet (5), unlock both sanding-sheet
clamps (4) and pull the sanding sheet out of its bracket.
Unperforated sanding sheets, e.g. from rolls or bulk stock
sold by the metre, can be perforated using the punch (11)
