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.

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.

PLUNGE BASE

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.

!WARNING Cutter diameter must be at least 1/4” smaller than

opening for the bit and cutter.
