Mount your workpiece in the jig properly. If the workpiece is not secure, it can be damaged when it moves.
The jigs utilize two mounting positions for workpieces - horizontal and vertical. Some joints require both, while
others require the use of a scrap board in the horizontal position (upper clamp) and the workpiece in the vertical
position (lower clamp).
Position your workpiece correctly left-to-right to produce symmetrical and tight-fitting joints.
Tear-out from the router bit can be reduced when scrap wood is positioned properly against the workpiece.
CLAMPS
The 4200 series jigs are equipped with two cam-action clamps (A) Fig. C1 with knobs (B) to adjust for workpiece
thickness, and levers (C) for quick clamping and releasing of workpieces.
NOTE: Use a scrap board (A) Fig. C2 to prevent misalignment (A) Fig. C3.

TEMPLATE MOUNTING
You can mount the templates in two positions on the jig(s) which allows the production of multiple types of joints
with each template. To reverse a template, loosen the template knobs (C) Fig. D1, remove the template (B) from the
base, rotate it 180 degrees horizontally, replace it on the base, and tighten the template knobs.
NOTE: Secure the templates by inserting the template brackets (A) Fig. D2 between the large template knobs (B)
Fig. D2 and the brass adjustment knobs (C). You can then make front-to-back adjustments by loosening the large
template knobs (B) and rotating the brass adjustment knobs (C).
