Noise/Vibration Information

Measured sound values determined according to EN 60745.

Typically the A-weighted sound pressure level of the product 
is 75 dB(A). Uncertainty K = 3 dB.
The noise level when working can exceed 80 dB(A).

Wear hearing protection!

Vibration total values a

h

 (triax vector sum) and uncertainty K 

determined according to EN 60745:
a

h

= 4.0 m/s

, K = 1.5 m/s

.

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.

Declaration of Conformity

We declare under our sole responsibility that the product de-
scribed under “Technical Data” is in conformity with the fol-
lowing standards or standardization documents: EN 60745 
according to the provisions of the directives 2011/65/EU, 
2004/108/EC, 2006/42/EC.

Assembly



Before any work on the machine itself, pull the mains 
plug.

Replacing the Sanding Sheet (see figure A)

When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 

8

, e. g., with a brush.

The surface of the sanding plate 

8

 is fitted with Velcro backing 

for quick and easy fastening of sanding sheets with Velcro ad-
hesion.

Press the sanding sheet 

10

 firmly against the bottom side of 

the sanding plate 

8

.

To ensure optimum dust extraction, pay attention that the 
punched holes in the sanding sheet match with the holes in 
the sanding plate.

Selecting the Sanding Sheet

Depending on the material to be worked and the required rate of material removal, different sanding sheets are available:
