Noise/Vibration Information

Sound emission values determined according to
EN 60745-2-4.
Typically the A-weighted sound pressure level of the product
is 76 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K

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.
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.
Replacing the Sanding Plate (see figure A)
The sanding plate 6 can be replaced, if required.
Unscrew the four screws completely 8 and remove the sand-
ing sheet 6. Put the new sanding sheet 6 on and retighten the
screws.
Replacing the Sanding Sheet
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 6 (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 (see figure B)
Sanding plates 6 fitted with Velcro backing can be used to fas-
ten sanding sheets with Velcro adhesion quickly and easily.
Before attaching the sanding sheet 9, free the Velcro backing
of the sanding plate 6 from any debris by tapping against it in
order to enable optimum adhesion.
Position the sanding sheet 9 flush alongside one edge of the
sanding plate 6, then lay the sanding sheet onto the sanding
plate and press firmly.
To remove the sanding sheet 9, grasp it at one of the tips and
pull it off from the sanding plate 6.
