Coarsely adjust the required radius by moving
the router compass and tighten the wing bolts
38 and 39.
The length can be fine adjusted with the fine-ad-
justment knob 40 after loosening the wing bolt
39. One revolution corresponds with a setting
range of 2.0 mm. One graduation mark on the
fine-adjustment knob 40 changes the setting
range by 0.1 mm.
Guide the switched on power tool over the
workpiece with the right handle 1 and the router
compass handle 37.
Routing with Guide Rail (see figure I)
Straight routing cuts can be carried out with
help of the guide rail 43.
The base spacer 42 must be mounted in order to
compensate the height difference.
Mount the router compass/guide-rail adapter 36
as shown in the figure.
Fasten the guide rail 43 to the workpiece with
suitable clamping devices, e. g. screw clamps.
Place the machine with the guide-rail adapter 36
mounted onto the guide rail.
Routing with Guide Bushing (see figures K–N)
The guide bushing 47 enables template and pat-
tern routing on workpieces.
In order to use the guide bushing 47, the guide
bushing adapter 44 must be inserted into the
guide plate 9 first.
Place the guide bushing adapter 44 from above
onto the guide plate 9 and tighten it firmly with
the 2 fastening screws 45. Pay attention that
the release lever for the guide bushing adapter
46 is freely movable.
Choose a suitable guide bushing, depending on
the thickness of the template or the pattern. Be-
cause of the projecting height of the guide bush-
ing, the template must have a minimum thick-
ness of 8 mm.
Actuate the release lever 46 and insert the guide
bushing 47 from below into the guide bushing
adapter 44. Ensure that the encoding keys clear-
ly engage in the grooves of the guide bushing.
Select a router bit with a diameter smaller
than the interior diameter of the guide
bushing.
Bosch Power Tools
To ensure that the distance from router bit cen-
tre and guide bushing edge is uniform, the guide
bushing and the guide plate can be adjusted to
each other, if required.
– Push the release lever 22 down and guide the
router to the stop in the direction of the base
plate 12. Let go of the release lever 22 again,
in order to lock this plunging depth.
– Unscrew the countersunk head screws 49.
Screw the pan head screws 48 into the holes
intended for this purpose in such a manner
that the guide plate 9 can be moved freely.
– Insert the centring pin 50 into the tool holder
as shown in the figure. Hand-tighten the
tightening nut so that the centring pin can
still be moved freely.
– Align the centring pin 50 and the guide bush-
ing 47 to each other by slightly moving the
guide plate 9.
– Tighten the pan head screws 48.
– Remove the centring pin 50 from the tool
holder.
– Push the release lever 22 and guide the
plunge router to the uppermost position.
For routing with the guide bushing 47 proceed
as follows:
– Guide the switched on power tool with the
guide bushing toward the template.
– Push the release lever 22 down and slowly
lower the plunge router until the adjusted
depth-of-cut is reached. Let go of the release
lever 22 again to lock this cutting depth.
– Guide the switched on power tool with the
protruding guide bushing alongside the tem-
plate applying lateral pressure.
