Operation
Adjusting the Depth-of-cut
(see figure F)
The adjustment of the depth-of-cut may on-
ly be carried out when the router is
switched off.
For coarse adjustment of the depth-of-cut, pro-
ceed as follows:
– Place the machine with the router bit mount-
ed on the workpiece to be machined.
– Open the clamping lever 10 on the motor unit
if locked.
– Turn the routing base 2 so that the
points against the
lower the motor unit until the router bit
touches the workpiece.
– Lock the clamping lever.
– Read the measuring value off the scale 8 and
note it down (zeroing). Add the desired
depth-of-cut to this value.
– Open the clamping lever and adjust the mo-
tor unit to the calculated scale value.
– Turn the routing base so that the
points against the symbol and lock the
clamping lever again.
– Check the carried out depth-of-cut adjust-
ment with a trial cut and correct it, if neces-
sary.
For fine adjustment of the depth-of-cut, proceed
as follows:
– With the clamping lever 10 open, turn the
routing base so that the
against the symbol.
– Adjust the desired depth-of-cut with thumb-

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Protect router bits against shock and im-
pact.
The feed motion of the router bit 4 must al-
ways be carried out against the rotation di-
rection of the router bit (up-grinding).
When routing in the rotation direction of the
router bit (down-cutting), the machine can
break loose, eliminating control by the user.
Use the machine only with the routing base
2 mounted. Loss of control over the machine
can cause injuries.
Before beginning the routing procedure,
check if the mark on the routing base is
positioned in line with the
