To begin a cut, clearly mark the cutting line, and rest the front of the footplate on the work. Engage the switch, and move the blade into the work using only enough forward pressure to keep the blade cutting steadily. Do not force, as this will not make the saw cut faster; let the blade do the work.

Choose blades carefully, as the ability of the jigsaw to follow curves, provide smoother finishes, or faster cutting is directly related to the type of blade used (See your Bosch Dealer).

For tight curves it is best to use a narrow or scroll blade.

When sawing metal or similar materials, shut off chip blower and apply coolant/lubricant alongside the cutting line.

When cutting thick wood, use the precision control button for increased lateral guidance of the saw blade.

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 cutting line. We do not recommend plunge cutting with a scroll blade.

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.

CIRCLE AND PARALLEL CUTTING GUIDE

(Not included, available as accessory)

This accessory is available at an extra cost. It is used for fast and accurate straight and circle cutting (Fig.12).

PARALLEL CUTTING

1.Insert bar of guide through lock knob clamp, then through the slots provided in foot, from either side of foot with the edge guide facing DOWN (Fig. 12).

2.Hook lock knob clamp onto edge of footplate, adjust fence to desired width, and securely tighten lock knob clamp (Fig. 12).

CIRCLE CUTTING

1.Before attaching the guide, draw a circle and predrill a 13/64” center hole in workpiece.

2.Drill or plunge cut near the circles edge, turn saw off and disconnect the plug from power source.

3.Attach guide to saw with edge guide facing UP as shown (Fig. 13).

4.Remove guide pin from end of guide, push pin through hole provided in guide, then into center hole of workpiece.

5.Measure the distance from the selected hole to the blade to be equal to the circle radius.

6.Insert plug into power source, hold the saw firmly, squeeze trigger and slowly push the saw forward. To make a hole, cut from inside the circle; To make wheels or discs, cut from the outside.

Cutting Tip: Cut slowly so the blade will stay straight in the cut. Place small wedges in the cut as shown in Fig. 13, to keep the inner circle from spreading when near the end of the cut.
