PR006 UNDERSCRIBE ATTACHMENT
(Included with PR20EVSNK. Also available as
optional accessory)
The PR006 Underscribe Attachment is used to
create precision-fit seams between two sheets
of laminate (Fig. 33), such as stile and rail
constructions and very large surfaces. It is
attached to the bottom of the PR001 Fixed
Base or PR011 Plunge Base. See PR011
Plunge Base for use of PR006 with that base.
Installation (Fig. 34)
1. Remove rear screws used to hold subbase
onto PR001 Fixed Base.
2. Attach infeed side of PR006 to the Fixed
Base using hex screw*
3. Insert eccentric adjuster into pocket on
outfeed side of PR006.
4. Attach outfeed side of PR006 to the Fixed
Base using hex screw*
*When used with PR007 Side-Handle Base,
the longer set of attachment screws should be
used.
Bit Installation
• The recommend bit for use with the
Underscribe Attachment is the Bosch
85213M with 1/8” cutting diameter.
• It should be installed according to the
instructions on page 9.
Bit Height Adjustment
After installing the bit, the height should be
adjusted as follows:
1. Lower bit until it just enters the recess that is
machined in the underscribe attachment’s
aluminum plate.
2. The tool is now ready for making a test cut.
Front-to-Back Adjustment
If necessary, the cutting point can be adjusted
front-to-back as follows (Fig. 35):
1. Loosen the two screws holding the
aluminum plate.
2. Using the pin wrench, adjust the eccentric
adjuster as follows:
• For a tighter seam, turn the eccentric
adjuster clockwise (as viewed from under
the base)
• For a looser seam, turn the eccentric
adjuster counterclockwise, (as viewed from
under the base)
3. Retighten the screws
4. Make a test cut
5. Repeat steps 1-4 as necessary
Creating a Seam
1. To create a precision seam, make sure he
guiding piece of laminate has a clean,
straight edge, because it will serve as the
guide for the underscribe attachment.
2. Contact cement should be applied to the
substrate core material and the guiding
piece of laminate up to 1” from its guiding
edge.
