counterclockwise.
3. Slide the stock rollers so that they are pressed
firmly up against the workpiece.
4. Tighten the knobs on the stock rollers by turning

NOTE: Make sure that the rollers are pressed against
the workpiece firmly enough to keep it from pulling
away from the fence, but not so tight that the workpiece
cannot slide freely from left to right.
USING AUXILIARY WOOD FENCE
When mortising an extra high workpiece, an auxiliary
fence can be fastened to the fence with wood screws
(not provided) through the holes in the fence. This
provides additional support for the workpiece during
mortising operation.
