Do not, under any circumstances, tighten the collet
u
with the tightening nut until a router bit has been fit-
ted. The collet may otherwise become damaged.
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Adjusting the routing depth (see figures D–E)
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.
Turn the locking wheel (14) anticlockwise approximately
half a revolution to unlock the depth-of-cut adjuster.
Push and hold the routing depth coarse adjustment
button (8). Move the drive unit up or down and adjust the
routing depth to approximately the required position. Re-
lease the (8) button.
Use the thumbwheel (10) to set the exact routing depth re-
quired. Each revolution of the thumbwheel alters the routing
depth by 1 mm.
Turn the locking wheel (14) clockwise approximately half a
revolution to lock the depth-of-cut adjuster.
Check the routing depth you have set by carrying out a prac-
tical test and correct it if required.
If you want to keep the tool at the routing depth you have
set, you can screw the fixing screw (11) into the routing
depth fine adjustment thumbwheel (10).
Starting Operation
Switching On and Off
To switch on the power tool, slide the on/off switch (5)
downwards so that I appears on the switch.
To switch off the power tool, slide the on/off switch (5) up-
wards so that 0 appears on the switch.
Working Advice
Protect router bits against shock and impact.

Routing direction and routing process (see figures F–G)
Routing must always be carried out with the work-
u
piece being moved against the direction in which the
router bit (17) 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.
Note: Be aware that the router bit (17) always protrudes
slightly from the base plate (12). Do not damage the tem-
plate or the workpiece.
Set the routing depth you want.
Switch on the power tool and guide it to the point you want
to machine.
Carry out the routing process with a uniform feed.
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.
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.
The following maximum workpiece dimensions apply for
edge and profile milling operations:
Material
Hardwood
Softwood
Plastic
MDF sheets
Plywood sheets
Maintenance and Service
Maintenance and Cleaning
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.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Clean the power tool with a vacuum cleaner, paint brush or
hand brush after use. Ensure that the guide columns are free
of wood dust. Apply a drop of lubricant to the smooth guide
column (19) (see figure I).
