* SCROLL/AUTO-SCROLL MODELS
Scrolling saws permit 360˚ rotation of the saw
blade without turning the saw, so intricate
designs may be cut with minimum effort. To
permit rotation of plunger turn lever, (Fig. 9)
to unlock. The plunger of your scrolling saw
can also be locked in (4) positions, 90˚ apart.
Note: If may be necessary to turn scrolling
knob slightly back and forth a to be sure the
plunger is locked in the desired position.
When manually scroll cutting, operate saw by
holding the handle with one hand and rotating
the scrolling knob manually with your free
hand. When auto scroll cutting, operate saw
by guiding the saw in the direction of cut with
applied pressure on the handle only (Fig. 9).

the blade could result in
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. 10)
On models with the scroll feature, it is advised
to unlock scroller knob and cut with the blade
in the REAR position of the blade holder. As
you cut, keep the saw foot edge flush against
the straightedge and flat on th work (Fig. 10).

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 line of cut line. We do not
recommend plunge cutting with a scroll blade
(Fig. 11).
To make sharp corners, cut up to the corner,
then back up slightly before rounding the
corner. After the opening is complete, go

broken blades and/or damage to the material
being cut.
Note: When scroll cutting intricate designs,
we recommend using a scroll cutting blade.
However, a standard blade can be used.
