Operation
Setting the routing depth
The routing depth must only be set while the power
u
tool is switched off.
– Place the power tool with a fitted router bit onto the work-
piece you want to machine.
– Reopen the wing bolt (11) on the routing base (2) in or-
der to set the required routing depth based on the scale
for setting routing depth (18) either by hand or with the
knurled screw (3).
– Close the wing bolt (11) on the routing base (2).
– Check the routing depth you have set by carrying out a
practical test and correct it if required.
Note: To set the router depth for a rounding router flush with
the guide plate (8), remove the routing adjustment aid (30)
from its holder and insert it into the opening on the under-
side of the guide plate (8) intended for this (see figure G).
Then feel out the edge of the router bit (5) using the routing
adjustment aid (30). Adjust the routing base height either by
hand or with the knurled screw (3) so that the routing ad-
justment aid (30) and the edge of the router bit (5) are
flush. Then close the wing bolt (11) on the routing base (2)
and secure the routing adjustment aid (30) in its holder
again.
Starting Operation
Preselecting the speed
You can preselect the required speed using the speed
preselection thumbwheel (12), even during operation.
Thumbwheel pos-
ition
1−2 10,000−14,000
3−4 18,000−24,000
5−6 26,000−30,000
The values displayed in the following table are guidelines.
The required speed depends on the material and the work-
ing conditions; it can be ascertained through practical tests.

After working for a long time at a low speed, you should let
the power tool rotate at no load for some time at maximum
speed to cool down.
Switching on/off
To switch on the power tool, set the on/off switch (13) to I.
To switch off the power tool, set the on/off switch (13) to 0.
Working Advice
Protect router bits against shock and impact.
u
Routing direction and routing process (see figure E)
Routing must always be carried out with the work-
u
piece being moved against the direction in which the
router bit (5) is turning (up cut). If the workpiece is
moved in the same direction as the router bit is turning
(down cut), the power tool may be pulled out of your
hands.
Only use the power tool when the routing base (2) is
u
fitted. Losing control of the power tool can cause injur-
ies.
Note: Be aware that the router bit (5) always protrudes
slightly from the base plate (9). Do not damage the template
or the workpiece.
Set the routing depth you want.
Switch on the power tool and guide it to the point you want
to machine.
Switch off the power tool after routing.
Do not put the power tool down before the router bit
u
has come to a complete stop. Application tools that are
still running can cause injuries.
Routing with Guide Bushing (see figures F1–F2)
Using the guide bushing (21), you can transfer contours
from templates or patterns to the workpiece.
Select the guide bushing that is suitable for the thickness of
the template or pattern. Due to the protruding height of the
guide bushing, the template must have a minimum thickness
of 8 mm (see figure F1).
Select a router bit with a diameter that is smaller than
u
the interior diameter of the guide bushing.
Unscrew the four cylinder screws on the underside of the
guide plate (8) and remove the guide plate.
Insert the guide bushing (21) into the guide plate (see
figure F2).
Screw the guide plate loosely onto the base plate (9) again.
The guide plate must still be able to move freely.
So that the distance between the centre of the router bit and
the edge of the guide bushing is the same everywhere, the
guide bushing and guide plate, if required, must be centred
on each other.
– Align the guide plate so that router bit and guide bushing
are centred on the opening in the guide plate.
– Hold the guide plate in this position and firmly tighten the
fastening screws.
