CENTERING THE SUB-BASE OR
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 use the edge
of the subbase or templet guides 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 relative to the jig.
To most precisely re-center the sub-base or
templet guides, attach the sub-base using the
optional Bosch RA1151 Centering Device.
Follow steps 1-8 (Fig. 19 & 20).
1. If a templet guide is to be centered, Install
the templet guide adapter and template
guide (optional attachments) as described
elsewhere in this manual.
2. Position the sub-base so that its pan-head
screw holes are over the matching set of
threaded holes in the base.
3. Insert the pan-head screws through the
sub-base and tighten them until they are
snug, but still allow the sub-base to move.
4. Prepare the Centering Device:
• Use narrow end of steel shaft when
inserting into 1/4" collet, wider end of
cone when inserting into 1/2" collet.
• When centering subbase or templet
guide that has opening of more than ½",
slide the wide plastic sleeve over the
steel shaft.
5. Slide centering sleeve through the sub-base
or templet guide and into collet. Tighten
collet nut with fingers to put slight grip on
centering cone.
6. Lightly press centering sleeve into sub-base
or templet guide to center.
7. Tighten the pan-head screws. Remove
centering sleeve.
8. The precision centering of the sub-base or
templet guide is complete.
