When fine-adjusting the routing depth, take care that the in-
dex mark 8 on the side of the plunge base points towards the
centre imprinted line. This measure ensures that there is suf-
ficient travel in both directions for readjustment of the plunge
depth.
When the plunge base 2 is lowered to the maximal plunge
depth, cutting deeper by means of the fine adjustment is not
possible, as the maximum travel has been utilised.
Fine adjustment is also not possible when the depth stop 11
faces against the turret stop 12.
Adjusting the Depth-of-cut on the Non-plunge Base
(see figure H)
For adjustment of the depth-of-cut, proceed as follows:
– Open the clamping lever for the non-plunge base 22.
– Coarse pre-adjustment of the routing depth is possible in 3
steps. For this, press clamping lever 25 and slide the rout-
ing motor 1 up or down in the non-plunge base 3, until it,
with the clamping lever 25 released, is locked in one of the
3 notches 26. The notches each have a clearance of
12.7 mm (0.5 ").
– The adjustment knob for depth-of-cut fine adjustment 24
is used for fine adjustment of the routing depth; turn clock-
wise to increase the routing depth, and anticlockwise to
decrease the routing depth. The travel on the scale of ad-
justment knob 24 is indicated in inch and millimeter. The
maximum setting range is 41 mm. The scale for depth-of-
cut adjustment 34 provides added orientation.
Example: The desired depth-of-cut is to be 10.0 mm; the
trial cut resulted in a cutting depth of 9.5 mm.
– Set the scale of the adjustment knob 24 to "0" without
changing the setting of the adjustment knob 24 itself. Then
set the adjustment knob 24 to the value "0.5" by turning in
clockwise direction.
– Check the selected depth-of-cut by carrying out another
trial cut.

Working Advice

Direction of Feed and Routing Process (see figure I)
The routing process must always be carried out against
the rotation direction of the router bit 18 (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.
For routing with the plunge base 2, proceed as follows:
– 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.
– Press the release lever for plunge action 7 down and slowly
guide the router down until the set depth-of-cut is reached.
Let go of release lever 7 again to lock this plunging depth.
– Carry out the routing process applying uniform feed.
– After finishing the routing process, guide the router up to
the uppermost position.
– Switch the power tool off.
2 610 008 242 | (18.7.11)
For routing with the non-plunge base 3, proceed as follows:
– Note: Take into consideration that for routing work with
the non-plunge base 3, the router bit 18 always protrudes
out of the base plate 13. Do not damage the template or
the workpiece.
– Adjust the required depth-of-cut; see Section "Adjusting
the Depth-of-cut".
– Switch the machine on and guide it to the location subject
to routing.
– Carry out the routing process applying uniform feed.
– Switch the power tool off. Do not place the power tool
down until the router bit has come to a standstill.
Routing with Auxiliary Guide (see figure J)
For working large workpieces, e. g., when routing grooves, a
board or straight edge can be securely fastened to the work-
piece as an auxiliary guide. The multifunction router can be
guided alongside the path of this auxiliary guide. When using
the plunge base 2, guide the guide plate (flattened side) of the
multifunction router alongside the auxiliary guide.
Shaping or Molding Applications
For shaping or molding applications without the use of a par-
allel guide, the router bit must be equipped with a pilot or a
ball bearing.
– Guide the switched on power tool from the side toward the
workpiece until the pilot or the ball bearing of the router bit
faces against the workpiece edge to be machined.
– Guide the power tool alongside the workpiece edge with
both hands, paying attention that the router is positioned
rectangular. Too much pressure can damage the edge of
the workpiece.
Routing with Parallel Guide (see figure K)
Slide the parallel guide 35 with the guide rods 36 into the
base plate 13 and tighten as required with the wing bolts 41.
Additionally, the parallel guide can be adjusted lengthwise
with the wing bolts 37 and 38.
Fine adjustment of the length is possible with the fine-adjust-
ment knob 39 after loosening both wing bolts 37. One revolu-
tion corresponds with a setting range of 2.0 mm. One gradu-
ation mark on the fine-adjustment knob 39 changes the
setting range by 0.1 mm.
The effective contact surface of the parallel guide can be ad-
justed with the edge guide 40.
Guide the switched on power tool with uniform feed and later-
al pressure on the parallel guide alongside the workpiece
edge.
Routing with the Router Compass (see figure L)
The router compass/guide-rail adapter 42 can be used for cir-
cular routing jobs. Mount the router compass as shown in the
figure.
Screw the centring screw 47 into the thread on the router
compass. Insert the point of the centring screw into the cen-
tre of the circular arc to be routed, paying attention that point
of the screw engages into the workpiece surface.
Coarsely adjust the required radius by moving the router com-
pass and tighten the wing bolts 44 and 45.
