Constant Electronic Control
Constant electronic control holds the speed
constant at no-load and under load, and ensures
uniform working 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 maxi-
mum 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
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.
When machining hard materials (e.g. hard-
wood) 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 con-
tinued planing at any given location on the work-
piece 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 ( ) with even feed.
Beveling Edges (see figure H)
The V-grooves in the front planer base plate al-
low quick and easy beveling of workpiece edges.
Depending on required bevel width, use the cor-
responding V-groove. For this, place the planer
with the V-groove onto the edge of the work-
piece and guide it along the edge.

Planing with Parallel/Beveling Guide
(see figures D–F)
Mount the parallel guide 20 or beveling guide 24
to the machine using the corresponding fasten-
ing bolt 23. Depending on the application,
mount the rebating depth stop 27 with fasten-
ing bolt 26 to the machine.
Loosen the locking nut 22 and adjust the re-
quested rebating width on the scale 21. Tighten
the locking nut 22 again.
Adjust the requested rebating depth according-
ly with the rebating depth stop 27.
Carry out the planing procedure several times
until the requested rebating depth is reached.
Guide the planer applying sideward supporting
pressure.
Beveling with the Beveling Guide
When beveling rebates
and surfaces, adjust
the required slope an-
gle with the angle ad-
justment 25.
