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
clamping 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 (Figs. 1,2,9)
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 (20) 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 (Figs. 1,9)
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 (Fig. 1/10)
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. 1,2,11-13)
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
surface!
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
wrench (SW 36).
Unlock the 0° lock (23) by pulling it out.
Set the desired wedge angle using the angle scale
(24).
Tighten the fixing nuts (13) again.
7.7 Adjusting miter guides (Fig. 14)
If the machine is used frequently, the gap between
the sliding faces of the saddle slide and cross slide
and the routing head can change. To guarantee
perfect functioning and movement, readjust the miter
guides once every year or so.
Undo the lock nuts (25).
Adjust the adjustment screws (26) so that the
pressure exerted on the miter guide is the same at
every adjustment screw.
Hold the adjustment screw (26) in position using
an Allen key (3 mm) and tighten the lock nuts (25)
again.
Tip: To ensure uniform adjustment, always tighten
the adjustment screws evenly from two sides,
starting from the outside.

8.1 Drilling and deep routing
Fit the drill chuck and tool as described in chapter
7.2 and lock them with the tie rod.
Tighten the drill chuck using the chuck key.
Set the correct rotational speed
(see chapter 7.1- 7.2).
Clamp the workpiece firmly using a machine vice
or by means of clamping claws.
Bring the compound table (2) into the desired
position (X or Y direction).
Set the depth stop (see chapter 7.5.1), making
sure that the tool does not touch the workpiece.
Remove from the working area any objects that
are no longer needed.
Switch the machine on and set the correct spindle
speed using the speed selector switch (6).
Carry out the drilling and routing work. Note:
Larger drill holes should be predrilled with a small
drill bit first. Withdraw the drill from the workpiece
several times while drilling so that the drill hole
remains free of chips.
The drilling or routing depth depends on the
