OPERATION

ORBITAL ADJUSTMENT KNOB

See Figure 9.

The blade of the saw cuts in an orbital motion. This feature is adjustable and provides faster, more efficient cutting. With orbital motion, the blade cuts through your work in the up- stroke but does not drag across your work in the downstroke. The “0” setting should be used when cutting materials with more resistance. The higher settings (3, 4) should be used when fast cutting in soft material is desired.

INSTALLING JIG SAW BLADES

See Figure 10.

Unplug the saw.

Remove the chip shield and the splinter guard if needed.

Lift the rapid change blade clamp until it stops.

Holding the rapid change blade clamp up, insert the saw blade as far as possible into the slot in the saw bar.

Check to make sure the back of the saw blade is centered in the groove of the roller guide.

Release the rapid change blade clamp. Make sure the blade is securely in place.

Replace the chip shield and splinter guard if needed.

REMOVING JIG SAW BLADES

See Figure 10.

Unplug the saw.

Remove the chip shield and the splinter guard if needed.

Lift the rapid change blade clamp until it stops.

Holding the rapid change blade clamp up, remove the saw blade.

NOTE: The jig saw is designed to use T-shank blades only.

STRAIGHT CUTTING

See Figure 11.

A straight cut can be made by clamping a piece of wood or straightedge to the workpiece and guiding the edge of the saw against it. Make the cut from one direction only. Don't cut halfway and complete the cut from the opposite end.
