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. Machining
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
setting of the depth stop (12).
After finishing the work, return the routing head to
the upper position and switch the machine off.
Clean the machine and clamping fixture and
lubricate if necessary.
8.1.1 Countersinking and center-drilling
Remember that countersinking should be carried
out with a low cutting speed and low feed, while
center-drilling should be carried out with a high
cutting speed and low feed.
8.2 Face routing
Clamp the clamping chuck and tool in place (see
chapter 7.1) and lock them with the tie rod (19).
Tighten the chuck using the chuck key.
Set the correct rotational speed
(see chapter 7.1-7.2).
Important: Do not change rotational speed
ranges (L and H) while the spindle is running!
Clamp the workpiece firmly using a machine vice
or by means of clamping claws.
Bring the table into the desired position (X or Y
direction).
Set the depth stop (see chapter 7.4.1), 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 desired spindle
speed using the speed selector switch (6).
Carry out the routing work. To do this, adjust the
compound table in the X and Y direction using the
hand cranks (see 7.5.3).
After finishing the work, switch the machine off
and return the routing head (1) to the upper
position.
Clean the machine and clamping fixture and
lubricate if necessary.
The work table must be cleaned and lubricated
again after the machine has been used.
9. Care and maintenance
Always pull out the power plug before carrying
out care and maintenance work! Machine
maintenance is required at regular intervals
(depending on how often it is used). The
maintenance work should be documented exactly.
Keep the tapered shanks and routing cutter clean.
For added protection, identical routing cutters are
