Cutting Tips

Face the good side of the material down and secure it in a bench vise or clamp it down. Draw cutting lines or designs on the side of the material facing up towards you. Then place the front edge of the saw foot on the work and line up the blade with the line to be cut. Hold the jigsaw firmly, turn it on, and press down (to keep the saw foot flat against the work) as you slowly push the saw in the direction of the cut.

Build up cutting rate gradually, cutting close to the line (unless you want to leave stock for

finish sanding). As you cut you may have to adjust or relocate the vise or clamps to keep the work stable. Do not force the saw or the blade teeth may rub and wear without cutting and the blade may break. Let the saw do most of the work. When following curves, cut slowly so the blade can cut through cross grain. This will give you an accurate cut and will prevent the blade from wandering.

 

 

ORBITAL ACTION

Note: In order to reach full orbital action, the

To activate, turn the lever to fast cut. To deactivate orbital action turn lever to smooth cut. When minimal splintering is desired we recommend using smooth cut position.

CUTTING WITH A STRAIGHTEDGE

Always use a rough cut blade when possible. Clamp a straightedge on the work parallel to the line of cut and flush with the side of the saw foot. (Either first mark the line of cut and then position the straightedge parallel and at the same distance as between the blade and the side edge of the foot or first mark the side edge of the foot and then clamp the straightedge on the mark and parallel to the cut line Fig. 7)

As you cut, keep the saw foot edge flush against the straightedge and flat on the workpiece (Fig. 7).
