7). FIG. 7 ORBITAL ACTION MODELS Orbital Action models, have a lever (Fig. 8) that will regulate the orbital action from "Smooth" position for normal up and down motion to maximum orbital action for faster cutting in softer materials. FIG. 8 ORBIT CONTROL LEVER To increase orbital action, turn the lever to a higher setting. To decrease orbital action turn ever to a lower setting. When minimal splintering is desired we recommend using "Smooth" position. SMOOTH LOW / MED FAST MILD STEEL / SOFT METALS METAL PLASTIC SOFT WOODS ALL MATERIALS HARD WOODS PLYWOOD ATTENTION: In order to achieve orbital action, the blade must be facing STRAIGHT FORWARD and the back of the blade must rest in the groove of the guide roller, and the foot must be all the way in the forward position. To adjust foot, lift foot adjustment lever and flip lever completely over, then push foot forward as far as possible and lower foot adjustment lever to maintain adjustment (Fig. 9). Orbital cut control is not observable when jigsaw is free running. Jigsaw must be cutting for orbital action to occur. The speed of cut is much more apparent in thicker materials such as 2 by lumber. FOOT BLADE ROLLER GUIDE FOOT ADJUSTMENT LEVER FIG. 9 -8 SCROLL MODELS (4540 & 4580 ONLY) locking tab, then lower the foot adjustment Scrolling saws permit 360° rotation of the saw lever to maintain adjustment (Fig. 11). blade without turning the saw, so intricate Note: It may be necessary to turn scrolling designs may be cut with minimum effort. To knob slightly back and forth to be sure the permit rotation of plunger turn lever, (Fig. 10) plunger is locked in the desired position. FIG. 10 LEVER HANDLE SCROLLING KNOB to scrolling. The plunger of your scrolling saw can also be locked in (4) positions, 90° apart. ATTENTION: When scroll cutting the blade must be moved away from the guide rollers. (Always move foot completely back). To adjust foot, lift foot adjustment lever and flip lever completely over, then push foot backwards as far as possible to engage When manually scroll cutting, operate saw by holding the handle with one hand and rotating the scrolling knob manually with your free hand. !CAUTION Excessive side pressure to the blade could result in broken blades and/or damage to the material being cut. Note: When scroll cutting intricate designs, we recommend using a scroll cutting blade. However, a standard blade can be used. FOOT BLADE ROLLER GUIDE FIG. 11 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. 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. 12). On models with the scroll feature, it is advised to lock scroller knob. As you cut, keep the saw foot edge flush against the straightedge and flat on the workpiece (Fig. 12). LINE OF CUT FOOT AGAINST STRAIGHT- EDGE CLAMPS FIG. 12 -9 PLUNGE CUTTING Plunge cutting is useful and time-saving in making rough openings in softer materials. It is not necessary to drill a hole for an inside or pocket cut. Draw lines for the opening, hold the saw firmly, tilt it forward so that the toe of the saw foot rests on the work, but with the blade well clear of the work. Start the motor, and then very gradually lower the blade. When it touches, continue pressing down on the toe of the saw foot slowly pivoting the saw like a hinge until the blade cuts through and the foot rests flat on the work. Then saw ahead on the line of cut line. We do not recommend plunge cutting with a scroll blade (Fig. 13). To make sharp corners, cut up to the corner, then back up slightly before rounding the corner. After the opening is complete, go back to each corner and cut it from the opposite direction to square it off. Do not try to plunge cut into hard materials such as steel. TOE OF FOOT FIG. 13 B...
