Installing the Routing Base (see figure A)
To start routing, the routing base (2) must be fitted back
onto the drive unit (1).
Open the wing bolt (12) on the routing base (2).
Slide the drive unit (1) into the routing base (2).
Close the wing bolt (12) on the routing base (2).
Note: The wing bolt (12) and the knurled screw (3) can be
exchanged with each other.
After assembly, always check that the drive unit is
u
firmly seated in the routing base.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Fitting the dust extraction adapter
To ensure optimum extraction, the dust extraction
adapter (29) must be cleaned regularly.
Connecting the Dust Extraction System (see figure D)
Insert the adapter for dust extraction (11) into the power
tool from the front. It audibly engages. To remove, grasp the
side of the adapter (11) and pull it off forwards.
Insert an extraction hose (dia. 35 mm) (30) (accessory) or a
dust extraction adapter (29) (accessory). Connect the dust
extraction hose (30) 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
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 (12) on the routing base (2) in or-
der to set the required routing depth based on the scale
1 609 92A 91T | (22.02.2024)
for setting routing depth (19) either by hand or with the
knurled screw (3).
– Close the wing bolt (12) on the routing base (2).
– Check the routing depth you have set by carrying out a
practical test and correct it if required.
Starting Operation
Preselecting the speed
You can preselect the required speed using the speed
preselection thumbwheel (16), 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.
Material Router bit dia-
meter [mm]
Hardwood (beech)
Softwood (pine)
Chipboard
Plastics
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.
Constant electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Working Advice
Protect router bits against shock and impact.
u
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
