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. 7)
As you cut, keep the saw foot edge flush
against the straightedge and flat on the
workpiece (Fig. 7).
ORBITAL ACTION
(Model 4380 only)
Orbital Action models, have a lever (Fig. 6)
that will regulate the orbital action from
smooth cut position for normal up and down
motion to maximum orbital action for faster
more aggresive cutting in softer materials.
To activate, turn the lever to fast cut. To
deactivate orbital action turn lever to smooth
cut. When minimal splintering is desired we
recommend using smooth cut position.
Note: In order to reach full orbital action, the
blade must be facing STRAIGHT FORWARD.
Orbital action 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.

ace 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
f
inish 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.
