Mounting/Replacing the Application Tool/
Accessory
If required, remove an already mounted application
tool/accessory.
For removing the application tool/accessory,
loosen the screw 11 with the hex key 12 and re-
move the application tool/accessory.
Mount the requested application tool/accessory
(e.g. plunge cut saw blade 10) in such a manner on
the tool holder 8 that the offset faces downward
(see illustration on the graphics page; marking on
the application tool/accessory is readable from
above).
Turn the application tool/accessory to a position
favourable for the respective job, and allow it to en-
gage into the cams of the tool holder 8. 12 different
positions are possible, each offset by 30 °.
For more intermediate positions, the adapter 13
(accessory) can be used: Allow the adapter to en-
gage with the smooth side onto the cams of the
tool holder 8 (see illustration on the graphics
page). Position the application tool/accessory onto
the adapter in any position.
Fasten the application tool/accessory with bolt 11.
Tighten the bolt with hex key 12 until the spring
washer of the bolt faces flush against the applica-
tion tool/accessory.
 Check the tight seating of the application
tool/accessory. Incorrect or not securely fas-
tened application tools/accessories can come
loose during operation and pose a hazard.

for quick and easy fastening of sanding sheets with

cro backing of the sanding plate 14 from any de-
bris by tapping against it in order to enable opti-
mum adhesion.
Position the sanding sheet 15 flush alongside one
edge of the sanding plate 14, then lay the sanding
sheet onto the sanding plate and press firmly.

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 reac-
tions 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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction sys-
tem suitable 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.
Connecting the Dust Extraction (see figure A)
For sanding, always connect the dust extraction.
Remove the application tool/accessory when
mounting the dust extraction 19 (accessory).
If required, assemble the parts of the dust extrac-
tion 19 as shown in the figure. Position the assem-
bled dust extraction onto the machine via the tool
holder 8. Turn the dust extraction in such a manner
that the cams of the dust extraction engage into the
corresponding recesses on the housing. Fasten
the dust extraction to the machine with the retain-
ing clip 17 as shown in the figure.
Pay attention that the felt ring 16 is undamaged
and faces tightly against the sanding plate 14.
Replace a damage felt ring immediately.
Place a vacuum hose 20 (accessory) onto the vac-
uum connection 18. Connect the vacuum hose 20
with a vacuum cleaner (accessory).
The vacuum cleaner must be suitable for the mate-
rial being worked.
