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.

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.
