HOW TO USE THE SAW

For your protection, effective control of this powerful saw requires two-handed operation. The saw may be operated either right-handed (Fig. 21) or left- handed (Fig. 22).

Support the work properly and hold the saw firmly to prevent loss of control which could cause personal injury.

Clamp the workpiece on a rigid support such as a bench or saw horses (Fig. 21). Mark the line of cut on the work. Be sure that the cut-off line is beyond the end of the support to the left only enough to allow proper operation of the telescoping guard. Place the front edge of the saw squarely on the workpiece before starting the motor. Sight the cutting line with the line of cut indicator (P) Fig. 15. Back the saw up slightly and start the motor. Move the saw forward, keeping the edge of the line indicator parallel to the line of cut.

Do not force the cut. Let the saw do the cutting at the rate of speed permitted by the type of cut and the type of workpiece. When the cut is complete, release the switch and allow the blade to stop before lifting the saw from the work. Be sure the lower blade guard is closed before putting the saw down.

CROSSCUTTING

Cutting directly across the grain of a piece of lumber is called crosscutting. Fig. 21 illustrates a crosscut operation. Position the work so that the cut will be on the left.

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 workpiece. If workpiece is supported on a large table, bench, or floor, place several pieces of scrap stock approximately one inch thick beneath the workpiece to allow clearance for the portion of the saw blade that extends thru the workpiece.

Place 2 x 4’s lengthwise between the horses and the workpiece to prevent large sheets of paneling or thin plywood from sagging.
