Noise/Vibration Information

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are: 

Sound pressure level 93 dB(A); Sound power level 

104 dB(A). Uncertainty K = 3 dB.

Wear hearing protection!

Vibration total values a

h

 (triax vector sum) and uncertainty K 

determined according to EN 60745:

a

h

= 3.5 m/s

2

, K = 1.5 m/s

.

The vibration emission 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 

another. It may be used for a preliminary assessment of expo-

sure.

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 poorly maintained, 

the vibration emission may differ. This may significantly in-

crease 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 pe-

riod.

Identify additional safety measures to protect the operator 

from the effects of vibration such as: maintain the tool and the 

accessories, keep hands warm, organise work patterns. 

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

f

Before any work on the machine itself, pull the mains 

plug.

Dust/Chip Extraction

f

Dusts from materials such as lead-containing coatings, 

some wood types, minerals and metal can be harmful to 

one’s health. Touching or breathing-in the dusts can cause 

allergic reactions and/or lead to respiratory infections of 

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered 

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials 

containing asbestos may only be worked by specialists.

– As far as possible, use a dust extraction system suita-

ble for the material.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the 

materials to be worked.

f

Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

Integrated Dust Extraction with Dust Box 

(see Fig. A1 – A4)

Mount the extraction adapter 

9

 onto the extraction outlet 

10

. 

Mount the dust box 

6

 onto the extraction adapter 

9

, ensuring 

that it engages.
To empty the dust box 

6

, press the latching levers 

11

 on the 

side of the dust box. Pull off the dust box.
Before opening the dust box 

6

, it is recommended to loosen 

the dust from the filter element by gently striking it against a 

firm support (as shown in the figure).
Grasp the dust box 

6

 by the recessed grip, fold the filter ele-

ment 

12

 upward and empty the dust box. Clean the thin 

plates of the filter element 

12

 with a soft brush.

Note: 

The belt sander has a high removal rate. To ensure op-

timum dust extraction, empty the dust box 

6

 regularly after 

5 minutes of operation and clean the filter element 

12

 regu-

larly.

External Dust Extraction

Mount a vacuum hose  onto the extraction outlet 

10

. Connect 

the vacuum hose  with a vacuum cleaner. An overview for the 

connection of various vacuum cleaners can be found at the 

end of these instructions.
The vacuum cleaner must be suitable for the material being 

worked.
When vacuuming dry dust that is especially detrimental to 

health or carcinogenic, use a special vacuum cleaner.

Changing the Sanding Belt (see figures B – D)

– Completely pivot out the clamping lever 

3

. The sanding 

belt 

2

 is now loose and can be removed.

– Mount the new sanding belt 

2

. Pay attention that the direc-

tion of the arrows on the inside of the sanding belt corre-

spond with the arrow direction on the machine housing.

– Pivot the clamping lever 

3

 back to its initial position.

– Pick up the machine and switch it on. The belt run is auto-

matically centred upon switching on and during the sand-

ing procedure.

If the sanding belt is not centred after switching on the ma-

chine, the belt run must be readjusted manually, if required. 

For this, readjust adjustment screw 

13

 at the front roll using a 

screwdriver until the sanding belt 

2

 runs in a position with dis-

tance of about 2 – 3 mm between the belt and the aluminium 

housing, see figure D. Should the belt run still not be centred 

after this, then the sanding belt 

2

 must be replaced.
