▼ CENTERING THE SUB-BASE OR
TEMPLATE GUIDES
Your PR111 plunge base features the
Bosch "Precision Centering Design".
Its subbase is precisely centered at
the factory. This positions the bit at
the center of the subbase and
optional template guides.
Precision centering allows you to use
the edge of the subbase or template
guides to closely follow jigs such as
straight guides, templates, 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
subbase or template guides, attach
the subbase using the optional Bosch
RA1151 Centering Device. Follow
steps 1-8 (Fig. 27).
