– Turn the adjustment knob 20 by 0.4 mm/4
graduation marks (difference from set to ac-
tual value) in clockwise direction and tighten
the wing bolt 14.
– Check the selected depth-of-cut by carrying
out another trial cut.
After adjusting the depth-of-cut, do not change
the position of the slide 16 on the depth stop 15
any more, so that the actual cutting depth can
be read on the scale 18.

Working Advice

Protect router bits against shock and im-
pact.
Direction of Feed and Routing Process
(see figure E)
The routing process must always be carried
out against the rotation direction of the
router bit 7 (up-cutting motion). When rout-
ing in the direction with the rotation of the
router (down-cutting), the machine can
break loose, eliminating control by the user.
– Adjust the required depth-of-cut; see Section
"Adjusting the Depth-of-cut".
– Place the machine with the router bit mount-
ed on the workpiece to be machined and
switch the power tool on.
– Push the release lever 22 down and slowly
lower the plunge router until the adjusted
depth-of-cut is reached. Let go of the release
lever 22 again to lock this cutting depth.
– Carry out the routing process applying uni-
form feed.
– After finishing the cutting process, guide the
plunge router upward again to the upper-
most position.
– Switch the power tool off.
Routing with Auxiliary Guide (see figure F)
For working large workpieces, e. g. when rout-
ing grooves, a board or wood strip can be fas-
tened to the workpiece as an auxiliary guide
alongside which the router can be guided. Guide
the router with the flattened side of the guide
plate along the auxiliary guide.

Shaping or Molding Applications
For shaping or molding applications without the
use of a parallel guide, the router bit must be
equipped with a pilot or a ball bearing.
– Guide the switched on power tool from the
side toward the workpiece until the pilot or
the ball bearing of the router bit faces
against the workpiece edge to be machined.
– Guide the power tool alongside the work-
piece edge with both hands, paying attention
that the router is positioned rectangular. Too
much pressure can damage the edge of the
workpiece.
Routing with Parallel Guide (see figure G)
Slide the parallel guide 29 with the guide rods
30 into the base plate 12 and tighten as required
with the wing bolts 5. Additionally, the parallel
guide can be adjusted lengthwise with the wing
bolts 31 and 32.
Fine adjustment of the length is possible with
the fine-adjustment knob 33 after loosening
both wing bolts 31. One revolution corresponds
with a setting range of 2.0 mm. One graduation
mark on the fine-adjustment knob 33 changes
the setting range by 0.1 mm.
The effective contact surface of the parallel
guide can be adjusted with the edge guide 34.
Guide the switched on power tool with uniform
feed and lateral pressure on the parallel guide
alongside the workpiece edge.
When routing with the parallel guide 29, the
dust/chip extraction should take place via the
special extraction adapter for the parallel guide
35. The extraction adapter 27 can remain
mounted.
Routing with the Router Compass
(see figure H)
The router compass/guide-rail adapter 36 can
be used for circular routing jobs. Mount the
router compass as shown in the figure.
Screw the centring screw 41 into the thread on
the router compass. Insert the point of the cen-
tring screw into the centre of the circular arc to
be routed, paying attention that point of the
screw engages into the workpiece surface.
