CENTERING THE SUB-BASE AND
TEMPLET GUIDES
Your router features the Bosch "Precision
Centering Design". Its sub-base is precisely
centered at the factory. This positions the bit at
the center of the sub-base and optional templet
guides. Precision centering allows you to closely
follow jigs such as straight guides, templets, and
dovetail fixtures without worrying about bit walk-
off from the intended cut line for any reason,
including the orientation of the router's handles.
In the event the sub-base screws are loosened or
removed, such when preparing the router for use
in a router table, here's how to re-center the sub-
base when reattaching it:
To quickly re-center the sub-base, attach the
sub-base using the set of flathead screws
(included) and the countersunk screw holes in
the sub-base. (Flathead screws have the tapered
heads.) The flathead screws and countersunk
holes will pull the sub-base into a position that is
very close to centered.

GUIDING THE ROUTER
The router can be guided through the work in any
of several ways. The method you use depends,
of course, on the demands of the particular job
and on convenience.
For routing operations such as grooving or
dadoing, it is often necessary to guide the tool
in a line parallel to a straight edge. One method
of obtaining a straight cut is to securely clamp a
board or other straightedge to the work surface,
and guide the edge of the router sub-base along
this path (Fig. 18).

OR — To most precisely re-center the sub-base,
attach the sub-base using the optional Bosch
centering cone, an optional Bosch templet guide,
and the set of pan-head screws (included). (Pan-
head screws have rounded tops.) Follow steps 1-
8.
1. Position the sub-base so that its pan-head
screw holes are over the matching set of
threaded holes in the base.
2. Insert the pan-head screws, not the flathead
screws, through the sub-base and tighten
them until they are snug, but still allow the sub-
base to move.
3. Insert templet guide (optional accessory) the
installed template guide adapter as described
elsewhere in this manual.
4. Slide centering cone (optional accessory)
through templet guide and into collet. Use
narrow end of cone when inserting into 1/4"
collet, wider end of cone when inserting into
1/2" collet.
5. Tighten collet nut with fingers to put slight grip
on centering cone.
6. Lightly press centering cone into templet guide
to center guide and sub-base.
7. Tighten the pan-head screws.
8. Remove centering cone. The precision
centering of the templet guide and sub-base is
complete.
