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.
To rout with the guide bushing (21), proceed as follows:
– Place the power tool with the guide bushing (21) on the
template.
– Move the power tool with the protruding guide bushing
along the template, applying pressure to the sides.
Edge or profile routing (see figure H)
For edge and profile routing without a parallel guide, the
router bit must be fitted with a pilot pin or a ball bearing.
While it is switched on, guide the power tool towards the
workpiece from the side until the pilot pin or the ball bearing
of the router bit is touching the side of the workpiece edge
that you want to machine.
Guide the power tool along the workpiece edge. Pay atten-
tion that the router is positioned perpendicularly. Too much
pressure can damage the edge of the workpiece.
Routing with a Parallel Guide (see figure I)
For routing with parallel edges, you can install the parallel
guide (22).
Secure the parallel guide (22) on the routing base (2) with
the knurled screw (4).
Set the required stop depth with the wing bolt on the parallel
guide (23).
While it is switched on, guide the power tool along the work-
piece edge with a uniform feed and while applying lateral
pressure to the parallel guide.
Routing with a Pilot (see figure J)
The pilot (24) helps when routing edges with router bits
without a pilot pin or ball bearing.
Fit the pilot to the routing base (2) using the knurled
screw (4).
Guide the power tool along the workpiece edge with a uni-
form feed.
Lateral clearance: To change the amount of material being
removed, you can adjust the lateral clearance between the
workpiece and the guide roller (27) on the pilot (24).
Loosen the wing bolt (25), set the lateral clearance you want
by turning the wing bolt (26), then retighten the wing
bolt (25).
Height: Set the vertical alignment of the pilot according to
the router bit you are using and the thickness of the work-
piece you want to machine.
Loosen the knurled screw (4) on the pilot, slide the pilot into
the required position and retighten the bolt.
