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.
