Constant Electronic Control
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perform-
ance.
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 ap-
prox. 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.
f
Apply the machine to the workpiece only when
switched on. Otherwise there is danger 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. 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 contin-
ued.
– Switch on the machine.
– Apply the supporting pressure onto the front part of the
planer base plate and slowly push the machine forward
(n). This tilts the park rest upward (o) so that the rear
part of the planer base plate faces on the workpiece again.
– Guide the machine over the surface to be planed (p) with
even feed.
Beveling Edges (see figure H)
The V-grooves in the front planer base plate allow quick and
easy beveling of workpiece edges. Depending on required
bevel width, use the corresponding V-groove. For this, place
the planer with the V-groove onto the edge of the workpiece
and guide it along the edge.
Planing with Parallel/Beveling Guide (see figures D–F)
Mount the parallel guide 21 or beveling guide 24 to the ma-
chine using the corresponding fastening bolt 23. Depending
on the application, mount the rebating depth stop 27 with fas-
tening bolt 26 to the machine.
Loosen locking nut 22 and adjust the desired rebating width.
Retighten locking nut 22.
Adjust the requested rebating depth accordingly with the re-
bating depth stop 27.
Carry out the planing procedure several times until the re-
quested 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 angle with the angle ad-
justment 25.
Storage Compartment for Planer Blade/Allen Key
A planer blade 16 and an Allen key 18 can be housed in the
storage compartment 3 as shown in the figure. To remove the
contents in the compartment, completely pull the storage
compartment for the planer blade/Allen key 3 out of the plan-
er.
Service Station (see figure I)
The service station 29 in the carrying case can be used for
holding the planer, e. g. for changing the blade.
f
Do not use the service station for stationary operation
of the planer.
