PRODUCT SPECIFIC SAFETY WARNINGS

5
Importance of Measuring Accurately
Most molding miscues involve incorrect
cuts or incorrect measurements. If set up
and used correctly, Crown-Cut eliminates
incorrect cuts. It’s up to you to avoid
incorrect measurements. Get help when
measuring long distances and double-check
your measurements whenever possible. As
the old woodworking adage goes: Measure
twice, cut once.
Types of Cuts
Crown-Cut is designed to make it easier to
get great results in four types of cuts with
crown or cove moldings: inside corners,
outside corners, left-over-right splice (or
scarf) joints and right-over-left splice (or
scarf) joints. The latter two cuts are used to
hide differences in moldings butted against
each other in long, straight runs.
Crown-Cut Setup
1. Place your molding (or a section of it)
upside down on the Crown-Cut.
2. From the back of the Crown-Cut,
loosen the screws holding the three
Fence Risers in Place and extend
the Fence Risers enough to support
the upper edge of the molding.
(Retract the Fence Risers when
not needed and for storage.) Fig. 1.
3. Loosen the knobs on the adjustable
Crown Stop and move it until both
flat sections on the back of the
molding are flush against the base
and fence of the Crown-Cut. Tighten
the knobs to lock in the final
position. Fig. 2.

Making 90° Corner Cuts
>Always position the Crown-Cut on the
miter saw so that it is clear of the
blade’s cutting path by at least 1/2".
>Hold the Crown-Cut and molding
securely against the fence of the
miter saw when making cuts.
>Always position moldings upside
down on the Crown-Cut. The jig will
not produce the desired results if the
molding is not positioned upside down.
>For best results, always provide
adequate support for long moldings.
>Always allow the blade to come to a
complete stop before lifting the miter
saw handle and removing the
Crown-Cut, the molding and/or any
offcut pieces.
> Do NOT attempt to cut pieces
shorter than 7".
> Always make tests cuts in scrap
molding to verify the fit of the joint
before cutting your final workpieces.
THESE WARNINGS PERTAIN TO ALL REMAINING STEPS:
>Keep hands and fingers out of the path of the saw
blade. Maintain awareness of the blade at all times.
>Never cut cross-handed.

Left-Over-Right Splice
To decide whether
to use a left-over-right or a right-over-left
splice joint, note whether the joint will
be visible to the right or to the left when
you enter the room. If it will be visible
on the left, use the left-over-right cut.
If it will be visible to the right, use
the right-over-left cut.

blade’s cutting path by at least 1/2”.
