WARNING: If the desired depth of cut is greater
than can be safely cut in one pass, make cuts in two
or more passes. Do not remove more than
1/8 in. with a single pass. Excessive depth of cut can
result in loss of control and the possibility of serious
personal injury.

ROUTING GROOVES PARALLEL TO AN EDGE
See Figures 17- 18.
You can use the scale provided on the woodworking sub-
base to cut a straight parallel line up to 1 in. from the edge
of the workpiece.
[] The intersection of the horizontal and vertical lines at
the center of the woodworking subbase indicates the
center of the cutter. This is also the center of groove
being cut.
[] For grooves more than 1 in. from the edge of
workpiece, align the center of desired groove on the
workpiece with the centerline on the woodworking
subbase. Then measure from the centerline on the
woodworking subbase to the guiding portion of the
straight guide. Tighten the knob on the straight guide
securely.
[] Using "C" clamps and a board to act as the straight
edge, place the cutter at the desired position on the
workpiece and make the cut from right to left.
NOTE: The board being used as a straight edge must
be 1/4 in. thick to prevent contact with the trim router
base. It must also be at least as long as the workpiece
in order to be a guide.
[] The thrust is from the trim router against the straight
edge.
[] Do not make a cut that is too heavy in one pass. If
a deep cut is required, make successive passes at
increasing depths with each new pass until you reach
the desired groove depth.
