The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Noise/Vibration Information
Noise emission values determined according
to EN 62841-2-4.
Typically, the A-weighted sound pressure level of the power
tool is 76 dB(A). Uncertainty K = 3 dB. The noise level when
working can exceed the volume stated. Wear hearing pro-
tection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-4:
2 2
a = 5.0 m/s , K = 1.5 m/s ,
h
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.
Fitting the base plate (GSS 160-1 A Multi) (see
figure A)
Unscrew the four screws (8) completely. Put a suitable base
plate on and retighten the screws.
Changing the sanding plate (see figure A)
If necessary, the sanding plate (6) can be replaced.
Unscrew the four screws (8) completely and remove the
sanding plate (6). Fit the new sanding plate (6) and
retighten the screws.
Changing the sanding sheet
Remove dirt and dust from the sanding plate (6), 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 B)
If the sanding plate (6) is fitted with a hook-and-loop fasten-
ing, sanding sheets with a hook-and-loop backing can be se-
cured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (6) be-
fore fitting the sanding sheet (9) to facilitate maximum adhe-
sion.
Position the sanding sheet (9) so that it is flush with one side
of the sanding plate (6), then place the sanding sheet on the
sanding plate and press it on firmly.
