Integrated Dust Extraction (see figure C)
A chip/dust bag (accessory) 20 can be used for
smaller jobs. Insert the sleeve of the chip/dust bag
firmly into the chip ejector 2. Empty the chip/dust bag
20 at regulary intervals to maintain optimum dust col-
lection.
Choice of Chip Ejector Side
With the selector lever 9, the chip ejector 2 can be
switched to right or left. Always press the selector
lever 9 until it engages in the end position. The
selected ejection direction is indicated by an arrow
symbol on the selector lever 9.
Operation

Operating Modes

Adjusting the Planing Depth
With the adjustment knob 1, the planing depth can be
adjusted variably from 0–4.0 mm using the planing
depth scale 4 (scale graduation = 0.1 mm).
Park Rest (see figure G)
The park rest 28 allows the machine to be set down
directly after operation, without danger of damaging
the working surface or the planer blade. While plan-
ing, the park rest 28 is tilted upwards thus enabling full
contact of the rear part of the planer base plate 10.

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 button for
the On/Off switch 5 and then press the On/Off
switch 6 and keep it pressed.
To switch off the machine, release the On/Off switch
6.
Note: For safety reasons, the On/Off switch 6 cannot
be locked; it must remain pressed during the entire
operation.
Constant Electronic Control
Constant electronic control holds the speed constant
at no-load and under load, and ensures uniform work-
ing performance.

Soft Starting
The electronic soft-starting feature limits the torque
when switching on and increases the working life of
the motor and drive belt.
Temperature Dependent Overload Protection
In case of overload, the speed is reduced. Allow the
machine to cool down by running it at maximum no-
load speed for approx. 30 seconds.

Working Advice

Planing (see figure G)
Set the required planing depth and place the front
part of the planer base plate 10 against the work-
piece.
¢ Apply the machine to the workpiece only
when switched on. Otherwise there is danger of
kickback when the cutting tool jams in the work-
piece.
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.
When machining hard materials (e.g. hardwood) as
well as when utilising the maximum planer width, set
only low planing depths and reduce planer feed, as
required.
Excessive feed reduces the surface quality and can
lead to rapid clogging of the chip ejector.
Only sharp blades achieve good cutting capacity and
give the machine longer life.
The integrated park rest 28 also allows for continued
planing at any given location on the workpiece after an
interruption:
– With the park rest folded down, place the machine
on the location of the workpiece where the planing
is to be continued.
– Switch on the machine.
– Apply the supporting pressure onto the front part
of the planer base plate and slowly push the
machine forward (‹). This tilts the park rest
upward (›) so that the rear part of the planer base
plate faces on the workpiece again.
– Guide the machine over the surface to be planed
(fi) with even feed.
