Adjusting the Depth-of-cut

With the cutting depth adjustment knob 18, the depth-of-cut
can be set. The cutting depth adjustment knob has set stops
for six biscuit dowel sizes.
Correlation of the set stops to biscuit dowel sizes and depths-
of-cut:

When using resharpened cutting discs, the depth-of-cut may
possibly need to be readjusted. For this, loosen the lock nut
19. The depth-of-cut can be reduced by turning the knurled
screw 20 in clockwise direction or increased by turning in an-
ticlockwise direction. Check the adjusted cutting depth by
carrying out trial cuts. Afterwards, firmly tighten the lock nut
19 again.
Setting the Adjustable Height Stop
With the adjustable height stop 9, the distance between the
upper surface of the workpiece and the intended groove can
be set.
To mount the adjustable height stop 9, place it on the angle stop
17 and screw it into the guide on the angle stop with knob 8.
Note: Do not exert any force when mounting! The stop 9
slides in easily when in the correct position.

With the knob 8, set the desired distance on the height scale
4. Then retighten the clamping lever 12.
In order to position the groove centred in the workpiece, the
adjustable height stop must be set to half of the workpiece
thickness.
Example: For an 18 mm thick workpiece, set the height scale
to 9 mm.
To remove the adjustable height stop 9, loosen clamping lever
12. With knob 8, unscrew the height stop upward out of the
angle stop 17.

Setting the Cutting Angle

The angle stop 17 enables easy cutting of grooves on mitre
18
joints.

To adjust the angle stop 17, loosen clamping lever 3. Pivot the
22
angle stop until the desired angle is set on the angle scale 5
(latching points are located at 0°, 45° and 90°). Then tighten
clamping lever 3 again.
 After adjusting the cutting angle, pay attention that
neither the adjustable height 9 stop nor the die attach-
ment plate 16 are in the path of the cutting disc. Check
as follows: With the machine switched off, simulate a cut
and push the cutter outlet e.g., against a table edge until
the cutting disc becomes visible. The cutting disc, when
driven out to the maximum position, may not touch the ad-
justable height stop 9 or the attachment plate 16.

Starting Operation

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
 The machine may be switched on only when the base
plate 33 is locked securely with the clamping screw 32
and the lock washer 31.
 Before switching on, check if the automatic returning
action of the motor unit functions properly. Push the
4
cutter outlet e.g., against a table edge until the cutting disc
becomes visible. When the pressure is released, the cut-
ting disc must be completely pulled back into the base
plate.
