Description
| |
|---|---|
The miter saw is a circular saw mounted to a mechanical arm that allows it to travel smoothly in the plane of the cut. It can tilt up and down and it can move in and out from a fixed column in the back. As such, it is less constrained than a radial-arm saw but more constrained than a hand-held circular saw. The workpiece is held firmly against a fence in the back of the machine and the saw cuts from the front to the back. The saw can be rotated with respect to the fence to do "miter" cutting. The blade can also be tilted laterally to make "bevel" and "compound" cuts.

Tool Safety
- Always treat this tool as a dangerous instrument, no matter how familiar you are with it. Don't become complacent or ignore safety rules.
- Use clamps to support the workpiece if possible. Keep hands at least 4 inches away from the path of the blade.
- Keep the workpiece stationary and press or clamp it against both the rear fence and the table.
- Do not feed the workpiece into the blade or cut "freehand" in any way.
- Never cross your hand over the line of cutting, either in front of or behind the saw blade.
- Inspect the workpiece. If it is bowed or warped, clamp it with the outside of the bow against the fence. Always make sure there is no gap between the workpiece, fence, and table along the line of the cut.
- No nails in the workpiece
- Cut only one piece at a time.
- Plan your cuts. Do not confine the workpiece in any way that may cause it to jam against the blade.
- When cutting a rod, reduce its tendency to roll under the spinning blade by clamping it or using a fixture.
- If the workpiece jams on the blade, turn the saw off and unplug it before reaching in to free up the piece.
