The stroke rate may be adjusted as described
earlier under "Variable Speed Dial". The best
results for a particular application is
Face 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
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 he
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.
REDUCED SPLINTER CUTTING
NOT AVAILABLE ON MODEL 4470
WITH TOOL-LESS BLADE HOLDER
Reduced splinter cutting is used when cutting
through plywood or a similar material. The
foot must be horizontal 0˚ (Fig. 7), and the use
of a hollow ground or smooth cutting blade is
recommended during reduced splinter
cutting.
Always disconnect the plug from power
source before making adjustments. Your saw
has an adjustable foot for doing reduced
splinter cutting. To adjust: loosen the foot
adjustment screw in the bottom of foot with a
* ORBITAL ACTION MODELS
Orbital Action models, have a lever (Fig. 2)
that will regulate the orbital action from "0"
position for normal up and down motion to
maximum orbital action for faster cutting in
softer materials.
To increase orbital action, turn the lever to a
higher number. To decrease orbital action
turn lever to a lower number. When minimal
splintering is desired we recommend using
"0" position.
Note: In order to reach full orbital action, the

PLUNGER SPEED
determined by experience, though as a general
rule, slower speeds are for denser materials
and faster speeds are for soft materials.

flat tip screwdriver, and slide the foot forward
so the slot in foot surrounds the blade on
both sides and securely tighten foot
adjustment screw.
Note: On auto-scrolling models, the blade
must be the REAR position of the blade
holder as shown in Fig. 5, in order for the slot
to surround the blade.
CAUTION
!
cutting, using the bevel adjustment, or any
other blade than hollow or smooth cutting
blades.
If finished materials must be cut face up, use
splinter free setting and reverse tooth blade
available at your dealer. Note: Do not use the
blade provided with your jigsaw during
reduced cutting since it is not hollow ground
or smooth cutting blade. These blades can be
purchased from your dealer.
HORIZONTAL

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.
