SAFETY WARNING KEY

24

> Keep hands and fingers out of the path of the saw blade. Maintain awareness of the blade at all times.

> Never cut cross-handed.

> 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 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 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 make tests cuts in scrap molding to verify the fit of the joint before cutting your final workpieces.

PRODUCT SPECIFIC SAFETY WARNINGS

Importance of Measuring AccuratelyMost 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 CutsCrown-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 Setup1. 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.

Cutting Inside 90° Corners1. To cut the left-side molding, swing the head of your miter saw 45° to the right (adjust the angle if your walls aren’t square) and position the Crown-Cut and molding to the right of the blade. Fig. 3.

2. Make sure the Crown-Cut is tight against the miter saw fence and at least 1/2" clear of the blade’s path. Also double-check that the molding is upside down in the Crown-Cut.

3. Line up your mark and carefully make the cut.

4. To cut the right-side molding, swing the head of your miter saw 45° to the left (adjust the angle if your walls aren’t square) and position the Crown-Cut and molding to the left of the blade. Fig. 4.



Cutting Outside 90° Corners1. To cut the left-side molding, swing the head of your miter saw 45° to the left (adjust the angle if your walls aren’t square) and position the Crown-Cut and molding to the right of the blade. Fig. 5.



4. To cut the right-side molding, swing the head of your miter saw 45° to the right (adjust the angle if your walls aren’t square) and position the Crown-Cut and molding to the left of the blade. Fig. 6.

Right-Over-Left Splice

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.

> 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”.





> Do NOT attempt to cut pieces shorter than 7”.
