cutting line with the line-of-cut indicator Fig. 9. Back saw up slightly and start motor. Move saw forward keeping the edge of line indicator parallel to line of cut.

CAUTION: Keep the cord away from cutting area, so it does not get hung up in the work being cut. See Fig. 14.

Do not force the cut. Let the saw do the cutting at the rate of speed permitted by the type of cut and the material being cut. When the cut is completed, release the switch and allow the blade to stop before lifting the saw from the work. On through-cuts, be sure the lower blade guard is closed, before setting the saw down.

CROSS-CUTTING

Cutting directly across the grain of a piece of lumber is called crosscutting. Fig. 14 illustrates a crosscut operation. Position the work so that the cut will be on the right, as shown.

RIPPING

Cutting wood lengthwise is referred to as ripping. This operation is performed in the same manner as crosscutting with the exception of supporting the material to be cut. If material is supported on a large table, bench or floor, several pieces of scrap stock approximately one inch thick should be placed beneath the material to allow clearance for the portion of the saw blade that extends through the material. Large sheets of paneling or thin plywood supported on saw horses should have 2 x 4’s placed lengthwise between the horses and the material, to prevent it from sagging in the center.

For narrow rip cuts, the rip guide, available as an accessory can be used. The saw is guided by keeping the inner face of the rip guide, Fig. 13, tight against the edge of the board.

For making wider cuts, such as might be made in plywood and wide sheets, a wooden guide strip, against which the left edge of the saw base can be guided, can be tacked or clamped to the work, as shown in Fig. 15. NOTE: The depth of cut must be adjusted to allow for the thickness of the wooden guide strip.
