Description
This tool 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 to cut a metal workpiece. The workpiece is clamped firmly against a fence in the back of the machine and the saw cuts when it is tilted down.
Superficially it resembles a wood-cutting miter saw but operates much differently. This machine has many fewer adjustments and degrees of freedom than the miter saw.
Use for:
- Hardened Steel
- Mild Steel
Do Not Use for:
- Aluminum
- Copper, Brass, Bronze
Soft metals will gum up the abrasive cutting disk.
- Zinc (or anything galvanized).
- Titanium

Basic Operation Instructions and Best Practices
1. Before operation, perform a quick safety check:
- Never use a damaged cutting wheel — Inspect for cracks or flaws. Damaged wheels may break or shatter during saw operation.
- Remove anything from behind the saw before operating.
2. Secure work piece in the chop saw’s vise.
- Work piece must fill vise to at least center of the vise’s back fence.
- Prevent mishaps: Understand how the rotating blade will try to move your part in the vise and position / stabilize your workpiece accordingly. (See Clamping Tips below.)
- Use the vise lever to fasten the workpiece, then tighten securely by turning the vise crank. (See features H and I.)
3. Perform the cut.
- Watch where you stand - avoid line of cutting wheel. Sparks and small pieces will tend to kick back toward wall, but can fly in any direction.

| Chop Saw clamping tips |
- Never start with cutting wheel inserted into or touching the workpiece. Press handle trigger to start the blade, then lower the blade.
- Vary force and travel speed to match the shape of work – judge by ear and by the sparks produced. No quick chops.
Clamping Tips
Be aware of blade rotation.
Angles are best cut with both legs facing down. This allows a safe cut, but is not optimal for miter cuts.
Another option for Angles: L facing backward, into the rotation of the blade.
Use square tube as a stabilizer. A spacer block slightly more narrow than the work piece can increase blade utilization.
Long workpieces must be supported to remain level. The cut-off end should be free to fall in order to avoid wheel binding.
