Mounting the Motor Unit
(see figure
)
G
With the clamping lever 10 opened, mount the
motor unit 1 by placing it into the routing base 2.
I Make sure that the "L" mark on the routing
base 2 points toward the line under the
"
" symbol on the motor unit 1. Otherwise
the machine can be damaged.
I After mounting, always check if the motor unit
sits tightly on the routing base. The pre-tension
of the clamping lever can be changed by read-
justing the nut
After mounting, has taken place, set the routing
base 2 to the " " symbol on the motor unit 1 and
lock the clamping lever 10.
Initial Operation
Always use the correct voltage: The voltage of
the power source must agree with the values on
the nameplate of the machine.
Switching On and Off
To start the unit, move the On/Off switch 12 to I.
To switch off the unit, move the On/Off switch 12
to 0.
Setting the Depth-of-cut
(see figure
)
H
I Adjust the depth-of-cut only when the trimmer
is switched off.
Place the trimmer on the workpiece to be worked.
Open the clamping lever 10, turn the routing
base 2 to the "
" symbol and slowly lower the
motor unit until the router bit touches the work-
piece. Fix the motor unit in this position by locking
the clamping lever 10.
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 10 and set the motor
unit to the calculated scale value. Turn the rout-
ing base 2 to the " " symbol and lock the clamp-
ing lever 10 again.
Check the adjusted depth-of-cut with a trial cut
and correct it, if necessary.
For fine adjustment of the depth-of-cut, set the
motor unit with the clamping lever 10 open to the
" " symbol. Adjust the desired depth-of-cut with
the knurled screw 3. Afterwards, lock the clamp-
ing lever to securely lock the motor unit in the
routing base.

Operating Instructions
Direction of Feed (see figure
The feed motion of the trimmer must always be
carried out against the rotation direction of the
router bit (up-grinding).
When milling in the direction with the rotation of
the router bit (down-cutting), the router can break
loose, eliminating control by the user.
Routing Process
I Use the machine only with the routing base
mounted. Loss of control over the machine
can cause injuries.
I Before beginning the routing procedure, check
if the routing base 2 is positioned at the
" " symbol on the motor unit 1.
Adjust the depth-of-cut as described previously.
Place the machine onto the workpiece and switch
it on with the On/Off switch 12.
After finishing the cutting process, switch the ma-
chine off with the On/Off switch 12.
Routing with Guide Bushing
The guide bushing 15 enables template and pat-
tern routing on workpieces.
Inserting the Guide Bushing 15
(see figure
K
)
Unscrew the 4 pan head screws on the bottom
side of the guide plate 6 and remove the guide
plate. Insert the guide bushing into the guide
plate and fasten it again to the base plate.
Routing Process
Select a router bit with a smaller diame-
ter than the inside diameter of the guide
bushing.
Place the machine with the guide bushing 15
against the template.
Guide the machine with the projecting guide
bushing along the template, applying slight lateral
pressure.
Note: The template must have a minimum thick-
ness of 8 mm, due to the projecting height of the
guide bushing.
