round base plate (7) and the optional square and D-shaped
base plates (accessories).
Fitting the Chip Shield for Edge Routing (see figure N)
The chip shield for edge routing (30) is particularly suitable
for use in combination with the dust extraction adapter for
edge routers (32). This ensures maximum dust extraction
when routing edges.
Fit the chip shield for edge routing (30) with the supplied
screw and click it audibly into the fixed routing base (2).
Fitting the dust extraction adapter for edge routing
(see figure N)
For routing edges, you can use the dust extraction
adapter (32) in addition to the chip shield for edge
routing (30).
Attach the dust extraction adapter(32) with the screw (18).
Remove the dust extraction adapter again when routing
smooth plane surfaces.
Fitting the dust extraction adapter for groove routing
(see figure O)
The dust extraction adapter (33) can be used for routing
work on the surface of a workpiece.
Fit the dust extraction adapter (33) with the supplied screw
and click it audibly into the fixed routing base (2).
Connecting the Dust Extraction System
Put an extraction hose (dia. 35 mm) (accessory) on the in-
stalled dust extraction adapter. Connect the dust extraction
hose to a dust extractor (accessory).
The dust extractor must be suitable for the material being
worked.
When extracting dry dust or dust that is especially detri-
mental to health or carcinogenic, use a special dust ex-
tractor.
Operation
Starting Operation
Preselecting the speed
You can preselect the required speed using the speed
preselection thumbwheel (3), even during operation.

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 (11) to I.
To switch off the power tool, set the on/off switch (11) to 0.
Constant electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Adjusting the Routing Depth (see figures E–F)
The routing depth must only be set while the power
u
tool is switched off.
For adjustment of the routing depth, proceed as follows:
– Place the power tool with a fitted router bit onto the work-
piece you want to machine.
– Open the clamping lever (10) if it is closed (➊).
– Align the rib (47) in the fixed routing base (2) with the
depth adjustment channel (48) and the unlocking sym-
bol (➋). Slide in the fixed routing base (2) until
roughly the required cutting depth is reached.
– Turn the fixed routing base (2) until the rib (47) matches
the locking symbol to make the fine depth adjustment
(➌).
– Precisely set the required routing depth with the
thumbwheel (4) (➍).
– Close the clamping lever (10) (➎).
Working Advice
Protect router bits against shock and impact.
u
Edge or profile routing (see figure G)
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.
