4 Electronics
The tool has full-wave electronics with
the following features:
Smooth start-up
The smooth start-up ensures the router starts
up jolt-free.
Constant speed
The pre-selected speed remains constant whether
the machine is in operation or in neutral position.
Brake (HL 850 EB)
After switching-off, the tool is electronically
brought to a standstill in 1.5 – 2 seconds.
5 Machine settings
Always remove the power supply plug
from the socket before carrying out any
work on the machine.
5.1 Chip thickness adjustment
- Open the lock (3.1) by pressing to the rear.
- Set the chip thickness by turning the handle
(3.2). The scale (3.3) indicates the set chip thick-
ness.
- Close the lock (3.1) by pressing to the front to
lock the set chip thickness.
The max. planing depth is 3.5 mm. So as no to
overload the machine, we recommend that a
maximum planing depth of 2.5 mm be set with a
plane width > 40 mm.
By turning the handle beyond the 0 mm marking,
you reach position P = Park position. In position P,
the planer head cutter is pulled back completely
behind the planer platen. Important: This does
not apply to the rustic planer heads.
5.2 Planing head, planer blade
Use only cutters which are sharp and
undamaged. Blunt cutters increase the
danger of kick-back and reduce the plan-
ing quality obtained.
The planer is equipped with planer head HK 82 SD
as standard series. The planer head has inclined,
fi tted cutters, which is why the cutters cannot be
reground.
Changing the planer head
- Press and hold in the spindle lock (1.6).
- Use the hexagon wrench (2.7) to open the screw
(2.2).
- Pull the planer head (2.6) from the shaft.
- Clean the shaft of any deposits that may be
present.
- Mount a new planer head on the shaft.
- Secure the new planer head with the clamping
fl ange (2.4), shim (2.3) and screw (2.2). Tighten
the screw (2.2) fi rmly.
Changing the cutters
- Use the hexagon wrench (1.4) to release the
three screws (4.1) in the planer head.
- Pull the spiral cutter (4.2) out of the planer head
at the side.
- Clean the support groove for the cutter. Impor-
tant : To prevent corrosion on the planer head,
the pH-value of the cleaning agent used must
be between 4.5 and 8.
- Push a new spiral cutter (4.2) with the labelled
side aligned to the rear planer platen into the
support groove of the planer head.
- Use a guide rail (4.3) to align the cutter so that
the front side is fl ush with the front and rear
platen of the planer.
- First tighten the middle screw, then the two
outer screws (4.1).
5.3 Fitting the guides
(partly accessories)
Rebating depth guide FA-HL
The rebating depth guide (2.1) is mounted in the
threaded hole (2.14) on the front right of the ma-
chine.
The stop can be infi nitely adjusted to between
0 and 30 mm in accordance with the scale. The
rebating depth which has been set can be read
against the notch (2.13).
Parallel guide PA-HL
The parallel guide (2.11) is fi tted in the threaded
hole (2.9) on the left side of the tool.
When planing along an edge a planing width of
between 0 and 82 mm can be set with the stop
after loosening the catch (2.10).
Angle stop WA-HL
The angle stop is secured in the tapped bore (2.9)
in the same way as the parallel stop.
5.4 Dust extraction
Always connect the machine to a dust
extractor.
Chip removal is actuated via the rocker lever (5.2)
