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

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.
