cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,

Cutting Tips
Face the good side of the material down and
s
ecure 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
finish 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.
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
t
he 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. 4).
As you cut, keep the saw foot edge flush
against the straightedge and flat on the
workpiece (Fig. 4).

Plunge cutting is useful and time-saving in
PLUNGE CUTTING
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. 5).
To make sharp corners, cut up to the corner,
then back up slightly before rounding the
corner. After the opening is complete, go back
to each corner and cut it from the opposite
direction to square it off. Do not try to plunge
cut into hard materials such as steel.

To adjust, push foot forward and pivot foot to

To return to 90˚, push foot forward and pivot
foot to 90˚. To lock, slide foot backward

METAL CUTTING
When cutting metal clamp material down. Be
extra certain that you move the saw along
slowly. Use lower speeds. Do not twist, bend,
or force the blade. If the saw jumps or
bounces, use a blade with finer teeth. If the
blade seems clogged when cutting soft metal,
use a blade with coarser teeth.
For easier cutting, lubricate the blade with a
stick of cutting wax, if available, or cutting oil
when cutting steel. Thin metal should be

sandwiched between two pieces of wood or
tightly clamped on a single piece of wood
(wood on top of the metal). Draw the cut lines
or design on the top piece of wood.
When cutting aluminum extrusion or angle
iron, clamp the work in a bench vise and saw
close to the vise jaws.
When sawing tubing and the diameter is
larger than the blade is deep, cut through the
wall of the tubing and then insert the blade
into the cut rotating the tube as you saw.
RIP FENCE AND CIRCLE CUTTING GUIDE
This accessory is available at an extra cost. It
is used for fast and accurate straight and

ATTACHING RIP FENCE
1. Insert bar of rip fence through the slots
provided in foot, from either side of foot with
the edge guide facing down (Fig. 7).
2. Thread the clamp screw through threaded
hole in tab on either the left or right side of
foot, and securely tighten clamp screw with a
screwdriver against rip fence bar (Fig. 7).

5. Insert plug into power source, hold the saw

the circle; To make wheels or discs, cut from
the outside.
Cutting Tip: Cut slowly so the blade will stay
straight in the cut. Place small wedges in the
cut as shown in Fig. 9, to keep the inner circle
from spreading when near the end of the cut.
