• Idling speed
The electronic circuit limits the idling speed. This means that
the noise level also remains low during idling.
• Constant speed
The speed of the planer shaft is electronically regulated to a
constant value, thus also providing a constant cutting speed
under load.
• Temperature protection
Extreme overload in continuous running will cause the motor
to overheat. An electronic temperature monitoring device is
fitted to provide protection against overheating (burning-out
of the motor). The electronic safety device switches off the
motor before a critical motor temperature is reached. After a
cooling period of approx. 3-5 minutes, the machine is once
again ready for use at full load. If the machine is kept running
(idling), the cooling period is reduced.
Do not work with the planer if the electronic control is
defective, since this may lead to excessive speeds. A defect
in the electronic control is indicated by the absence of a smooth
run-up, a higher noise level at idle or the fact that no speed
control is possible.

Machine settings

Always disconnect the plug from the power
supply before making any adjustments to the machine or
installing or removing any accessory!

Chip thickness adjustment

After the interlock (2.2) has been released by pushing it
backward, the chip thickness can be infinitely adjusted
between 0 mm and 3.5 mm by turning the supplementary
handle (2.3). The chip thickness which has been set can be
read in the scale window (2.1). One division corresponds to a
chip removal of 0.1 mm.
If a constant chip thickness is to be set the interlock must be
pressed forward again after the chip thickness has been
adjusted. If the chip thickness has to be varied during
operation (fitting work) the interlock should be left open.
The supplementary handle can be turned beyond the 0 mm
mark to reach the P (= Park) position, in which the spiral
cutter is completely retracted. This is, however, not the case
with the rustic planer heads.
Always ensure, therefore, that when setting the
machine down on a surface the parking device (1.8) at the
end of the planer platen is correctly extended.

Planer heads and spiral cutters

The planer heads available have been approved by the official
inspectorate in Germany for the woodworking industry and
carry the "BG-Test" numbers 045-014 (standard planer heads)
and 045-015 (rustic planer heads).
The planer is equipped as standard with the planer head HK
82 SD, which incorporates a carbide-tipped spiral cutter HM
82 SD. This cutter produces a straight-sided 90° rebate.
The carbide-tipped cutter is provided with special spiral
grinding at the cutting and back angles. It can therefore not
be resharpened.
Always disconnect the mains plug from the
socket before changing the planer head or planer blade.
a) Changing the planer head
Use the spindle stop (3.1) to lock the planer shaft and unscrew
the allen bolt (3.5) from the planer head (3.2) using the allen
key (3.6). Remove the planer head from the planer shaft.
Before fitting the new planer head clean the planer shaft to
remove any dust residues.
The planer head can be fitted to the planer shaft in reverse
order using the clamping flange (3.3), washer (3.4) and allen
bolt (3.6).
