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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Use dust extraction whenever possible.
– 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, al-
ways 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 ejector.
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.

Operation
Operating Modes
Adjusting the Planing Depth
With the adjustment knob 2, the planing depth
can be adjusted variably from 0–1.5 mm using
the planing depth scale 1 (scale graduation =
0.1 mm).
Park Rest (see figure D)
The park rest 17 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 17 is tilted
upwards thus enabling full contact of the rear
part of the planer base plate 8.

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, first push the lock-off but-
ton for the On/Off switch 4 and then press the
On/Off switch 5 and keep it pressed.
To switch off the machine, release the On/Off
switch 5.
Note: For safety reasons, the On/Off switch 5
cannot be locked; it must remain pressed during
the entire operation.
Working Advice
Planing (see figure D)
Set the required planing depth and place the
front part of the planer base plate 8 against the
workpiece.
Apply the machine to the workpiece only
when switched on. Otherwise there is dan-
ger of kickback when the cutting tool jams in
the workpiece.
Switch the machine on and guide the machine
with even feed over the surface to be planed.
To achieve high-grade surfaces, work only with
low feed and apply pressure on the centre of the
planer base plate.
