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 (triax vector sum) and uncertainty K
h
determined according to EN 60745:

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.

Assembly
Before any work on the machine itself, pull the mains
plug.
Dust/Chip Extraction
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.

PT/ETM9
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.
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.
