When assembling the planer blade, ensure that
it is seated properly in the blade holder of the
clamping element 11 and aligned flush at the
side edge of the rear planer base plate 7. After-
wards tighten the 2 fastening screws 12 again
with the Allen key 14.
Note: Before restarting, check if the fastening
screws 12 are tightened well. Rotate the blade
drum 10 by hand and ensure that the planer
blade does not graze.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– As far as possible, use a dust extraction
system suitable for the material.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Clean the chip ejector 3 regularly. Use a suitable
tool (e.g., a piece of wood, compressed air,
etc.) to clean a clogged chip ejector.
Do not reach into the saw dust ejector with
your hands. They could be injured by rotat-
ing parts.
To ensure optimum extraction of dust/chips,
always work with external dust extraction or a
chip/dust bag.

External Dust Extraction (see figure C)
An extraction hose (Ø 35 mm) 15 (accessory),
can be attached on either side of the chip ejec-
tor.
Connect the vacuum hose 15 to a vacuum clean-
er (accessory). An overview for connecting to
various vacuum cleaners can be found at the
end of this manual.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Integrated Dust Extraction (see figure C)
A chip/dust bag (accessory) 16 can be used for
smaller jobs. Insert the sleeve of the chip/dust
bag firmly into the chip ejector 3. Empty the
chip/dust bag 16 at regulary intervals to main-
tain optimum dust collection.
Choice of Chip Ejector Side
With the selector lever 6, the chip ejector 3 can
be switched to right or left. Always press the se-
lector lever 6 until it engages in the end posi-
tion. The selected ejection direction is indicated
by an arrow symbol on the selector lever 6.
Operation
Operating Modes
Adjusting the Planing Depth
With the adjustment knob 2, the planing depth
can be adjusted variably from 0–3.1 mm using
the planing depth scale 1 (scale graduation =
0.1 mm).
Park Rest (see figure G)
The park rest 25 allows the machine to be set
down directly after operation, without danger of
damaging the working surface or the planer
blade. While planing, the park rest 25 is tilted
upwards thus enabling full contact of the rear
part of the planer base plate 7.
Note: The park rest 25 may not be removed.
