7.3.2 Removing the tool from the work spindle:
Switch the machine off and unplug the power
plug.
Remove the spindle guard (15).
To fix the work spindle in position, insert the
locating pin (17) into the side of the spindle bush.
Loosen the tie rod by turning the open-end wrench
(SW10) anticlockwise.
Loosen the tapered shank (18) carefully using a
rubber hammer and remove it from the spindle
bush. To avoid injury, always use a cloth to hold
the routing cutter!
Reattach the spindle guard (15).
7.3.3 Handling the drill chuck
Only cylindrical tools with the stipulated maximum
shaft diameter may be clamped in the drill chuck
(9). Only use a tool that is sharp and free of
defects. Do not use a tool whose shaft is
damaged or which is deformed or flawed in any
other way. Use only accessories or auxiliary units
that have been approved by the manufacturer.
Insert the shaft of the tool all the way into the drill
chuck (9) and tighten it using the supplied chuck
key.
Pull out the chuck key. Ensure that the clamped
tool is firmly seated.
Important: Do not leave the chuck key in. Doing
so will cause the chuck key to be catapulted out,
which could cause injury.
7.4 Clamping the workpieces
Important: Workpieces must always be clamped
tightly! This is important both for your own safety and
for the work results. If the workpiece is not clamped
tightly, it could be torn out by the feed force of the
routing cutter and catapult out.
The best thing to do is to use a machine vice (not
included in delivery). The machine vice can be
secured firmly to the compound table of the machine
using tightening screws and slide blocks. Before
tightening the screws for the last time, use a dial
gauge to make sure that the machine vice is aligned
exactly parallel to the saddle guides.
You can also use suitable clamping claws (not
included in delivery) to fix the workpiece to the
machine table. You must make sure that the clamp-
ing claws are the right size to guarantee that the
workpiece is fixed securely.
7.5 Feed (Figs. 7,8)
All feed movements must be executed by hand.

7.5.1 Normal feed of the routing head
Pull the star handle (14) of the feeder completely
away from the machine.
The tool can now be brought rapidly towards the
workpiece using the star handle.
Normal feed is used for drilling operations.
The drilling or routing depth can be limited in the z
direction by means of the depth stop (12).
To do so, loosen the locking handle on the depth
stop (12).
Set the depth stop to the required position and
tighten the locking handle (20) again.
The position of the feed can be read on the scale
(21).
7.5.2 Fine feed of the routing head
Push the star handle (14) towards the routing
head (1) so that the teeth of the jaw clutch (27)
intermesh.
The routing cutter can now be positioned exactly
using the wheel selector for fine feed (7).
One notch on the scale ring corresponds to 0.02
mm of travel of the table.
Once the desired routing depth has been set, the
routing head (1) must be fixed in position using
the relevant clamping lever (28).
7.5.3 Feed of the compound table
The compound table (2) of the machine can be
moved manually in two perpendicular directions
(X,Y).
For routing jobs, the feed is executed by operating
the cranks (10,11).
The zero position of the travel can be set using
the scale ring on the hand cranks.
One notch on the scale ring corresponds to 0.02
mm of travel of the table.
If one traversing axis (X or Y) of the table is not
used, it should be clamped tight by means of the
relevant clamping lever (22).
7.6 Swiveling the routing head (Fig. 1,2,9)
The routing head can be swiveled 45° to the left or
right to enable chamfers or V-grooves to be cut.
Important: Before starting adjustment, make sure
that the machine is screwed tight to the working sur-
face!
Switch the machine off.
Hold the machine head (1) tightly with one hand to
prevent it from tipping over.
Loosen the fixing nuts (13) using an open-end
