10.2.1. General Operating Tips

When you feed the material through the tool horizontally, or move the carriage over the material

vertically, do it slowly, smoothly, and (whenever possible) without stopping. Overfeeding results in

poor-quality cuts, shortened blade life, and motor overloading.

Be careful when setting material onto the rollers. Do not drop heavy material onto the rollers or

damage to the rollers may result.

Place the workpiece onto the tool with its back side facing you, this provides the smoothest possible

cut on the face side of the panel. As a circular saw blade cuts up through wood, the fibers on top

splinter off, a condition known as tear-out (usually worse on cross-cutting). If you must cut the board

face-up or if both sides will show, score the cut line with a utility knife before cutting.

Panels being cut HORIZONTALLY must always be fed RIGHT to LEFT and VERTICALLY from TOP to

BOTTOM. This way they are fed against the rotation of the saw blade.

Panel saws are intended for cutting large panels down to size. As the overall panel size becomes smaller

and smaller, other types of sawing tools become more convenient and safer to use.

10.2.2. Operating Procedure: Crosscutting (Vertical Cutting)

WARNING: To reduce the risk of injury, do not place your hands on or under the

carriage or in the path of the saw blade.

A crosscut is a vertical cut that must always be done from the top to the bottom of a workpiece as

shown in Figure 1. (See also “General Operating Tips” above.)

a. Position the saw motor in the crosscutting position with the blade oriented vertically. To rotate

the turntable, pull out both indexing pins, and pivot the turntable until they snap into the

appropriate holes.

b. Loosen the carriage lock and move the carriage to the top

of the guides.

c. Place the workpiece on top of the rollers. Be careful not to

drop the material on the rollers.

NOTE: When crosscutting (vertical cuts), the workpiece

must be supported on at least two rollers (Figure 1) for

safe operation and accurate cutting.

d. Slide the workpiece to the desired position, using the

crosscut rulers or optional gauging systems (Stop Bar or

Quick Stop) as measures.
