One of the distinctive and important features of the Porter-Cable jigsaw is the ability to start the cut, (in wood only) within an area, without making drilled holes first. This is especially important when making cutouts for electrical outlets in finished walls, openings in cabinet tops for sinks and openings for plumbing fixtures.

NOTE: When plunge cutting, it is recommended the orbit knob be set to position “3”.

First, measure the area to be cut out and mark it clearly with a pencil, chalk or

scriber. Choose a convenient starting point and hold the jigsaw over the point and inside the line of waste. Tip the machine forward until the front edge of the base rests firmly on the surface of the material with the tip of the blade clear of the work surface, as shown in Fig. 8. Turn motor “ON” and slowly lower the back of the machine until the base is fully seated on the surface of the work. Now, guide the cutting along the inside of the marked area. If sharp corners are desired cut right up to the corner of the marked edge. Stop and back up just a bit, start the turn and cut along the side. Do the same at each corner until you end up where you started. Then, go back and cut into each corner from the opposite direction. The base of the machine is wide enough so you will have a solid guiding surface on either side of the cut.

BASE ADJUSTMENT

The base may be adjusted two ways, front to rear and tilted either left or right for making bevel cuts. The base has a detent at the 0 (90 degree) setting and at 15, 30 and 45 degree setting both left and right of center.

The base is set at its forward most position at the factory. The base can be adjusted to the rear for making flush cuts around walls and other similar areas. To move the base forward or backward, turn the saw on its side, loosen screw (A), Fig. 9, move the base to the desired position and retighten the screw.

NOTE: When making bevel cuts, the base should be set to the forward most position (Fig. 9).
