Routing with Guide Bushing
(see figures H1–H3)
The guide bushing 16 enables template and pat-
tern routing on workpieces.
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. (see figure H1)
Select a router bit with a diameter smaller
than the interior diameter of the guide
bushing.
– Unscrew the four pan head screws on the
bottom side of the guide plate 6 and remove
the guide plate.
– Insert the guide bushing 16 into the guide
plate. (see figure H2)
– Screw the guide plate loosely onto the base
plate 7 again. The guide plate must be able to
move freely.
To ensure that the distance from router bit cen-
tre and guide bushing edge is uniform, the guide
bushing and the guide plate must be adjusted to
each other, if required.
– Align the guide plate in such a manner that
router bit and guide bushing are centred to
the guide plate opening. (see figure H3)
– Hold the guide plate in this position and
tighten the fastening screws.
For routing with the guide bushing 16 proceed
as follows:
– Place the machine with the guide bushing 16
against the template.
– Guide the switched on power tool with the
protruding guide bushing alongside the tem-
plate applying lateral pressure.
Bosch Power Tools
Shaping or Molding Applications (see figure I)
For shaping or molding applications without the
use of a parallel 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 machine alongside the workpiece
edge. Ensure rectangular support. Excessive
pressure can damage the edge of the work-
piece.
Routing with Parallel Guide (see figure K)
For edge-parallel cuts, mount the parallel guide
17.
– Fasten the parallel guide 17 to the routing
base 2 with wing bolt 18.
– Adjust the desired depth setting with wing
bolt 19 on the parallel guide.
– Guide the switched on power tool with uni-
form feed and lateral pressure on the parallel
guide alongside the workpiece edge.
Routing with Roller Guide (see figure L)
The roller guide 20 is used for routing edges
with router bits without pilot or ball bearing.
– Fasten the roller guide 2 to the routing base
with wing bolt 18.
– Guide the machine with uniform feed along-
side the workpiece edge.
Lateral Clearance: In order to change the
amount of material removal, the lateral clear-
ance between workpiece and the guide roller 21
of the roller guide 20 can be adjusted.
– Loosen wing bolt 22, adjust the desired later-
al clearance by turning wing bolt 23 and
tighten wing bolt 22 again.
Height: Adjust the vertical alignment of the roll-
er guide depending on the router bit in use and
the thickness of the material to be worked.
– Loosen wing bolt 18 on the roller guide,
move the roller guide to the desired position
and tighten the wing bolt again.
