After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
Switching On and Off
Adjust the depth-of-cut before switching on or off; see Sec-
tion “Adjusting the Depth-of-cut”.
To start the machine, press the On/Off switch 19 and keep it
pressed.
To lock the pressed On/Off switch 19, press the lock-on but-
ton 18.
To switch off the machine, release the On/Off switch 19 or
when it is locked with the lock-on button 18, briefly press the
On/Off switch 19 and then release it.
Constant Electronic Control
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perform-
ance.
Adjusting the Depth-of-cut
f The adjustment of the depth-of-cut may only be carried
out when the router is switched off.
For coarse adjustment of the depth-of-cut, proceed as fol-
lows:
– Place the machine with the router bit mounted on the
workpiece to be machined.
– Set the scale for fine adjustment 2 to “0”.
– Set the step buffer 8 to the lowest position; the step buffer
engages noticeably.
– Loosen the clamping lever for depth-of-cut coarse adjust-
ment 5 by turning in counterclockwise direction so that the
depth stop 4 can move freely and faces against the step
buffer 8.
– Push the release lever 16 downward and slowly lower the
plunge router until the router bit 22 touches the surface of
the workpiece. Let go of the release lever 16 again to lock
this plunging depth.
– Set the scale for coarse adjustment of the depth-of-cut 6 to
“0”.
– Adjust the required depth-of-cut by turning the adjustment
knob for coarse adjustment 7 and reading the scale 6. Pay
attention not to readjust the rotatable scale 6.
– Lock the clamping lever for depth-of-cut coarse adjust-
ment 5 by turning in clockwise direction and slide the rout-
er upward.
For deep cuts, it is recommended to carry out several cuts,
each with little material removal. By using the step buffer 8,
the cutting process can be divided into several steps. For this,
adjust the desired depth-of-cut with the lowest step of the
step buffer and select the higher steps first for the initial cuts.
The clearance of the steps can be changed by screwing the
adjusting screws further in or out.
After a trial cut, the depth-of-cut can be set exactly to the de-
sired measure by turning the adjustment knob 1; turn in
clockwise direction to increase the cutting depth and in anti-
clockwise direction to decrease the cutting depth. The scale 2
can be used for guidance. One full turn corresponds with a
setting range of 2.0 mm; a graduation mark on the top edge of
the scale 2 corresponds with a 0.1 mm change of the setting
range. The maximum setting range is ± 8 mm.
Example: The desired depth-of-cut is to be 10.0 mm; the trial
cut resulted in a cutting depth of 9.6 mm.
– Lift up the router and place e. g. a piece of scrap wood un-
der the guide plate 12 so that the router bit 22 cannot
touch the workpiece when lowering it. Push the release le-
ver 16 down and slowly lower the plunge router until the
depth stop 4 faces on the step buffer 8.
– Turn scale 2 to “0” and release the clamping lever for
depth-of-cut coarse adjustment 5 by turning anticlock-
wise.
– Turn the adjustment knob for coarse adjustment of depth-
of-cut 7 by 0.4 mm/4 scale marks (difference from nomi-
nal to actual value) in clockwise direction and lock the
clamping lever for depth-of-cut coarse adjustment 5 also
by turning in clockwise direction.
– Check the selected depth-of-cut by carrying out another
trial cut.
Working Advice
f Protect router bits against shock and impact.
Direction of Feed and Routing Process (see figure C)
f
The routing process must always be carried out against
the rotation direction of the router bit 22 (up-cutting
motion). When routing in the direction with the rota-
tion of the router (down-cutting), the machine can
break loose, eliminating control by the user.
– Adjust the required depth-of-cut; see Section “Adjusting
the Depth-of-cut”.
– Place the machine with the router bit mounted on the
workpiece to be machined and switch the power tool on.
– Push the release lever 16 down and slowly lower the
plunge router until the adjusted depth-of-cut is reached.
Let go of the release lever 16 again to lock this cutting
depth.
– Carry out the routing process applying uniform feed.
– After finishing the cutting process, guide the plunge router
upward again to the uppermost position.
– Switch the power tool off.
