11. This saw uses 5 in. long pin or plain
end type blades only.
12. Blades wear faster when cutting
plywood or particle board which
is very abrasive. Angle cutting in
hardwoods reduces blade tooth set
faster due to the blade deflection.
FREEHAND CUTTING (FIG. V)
To avoid injury from an accidental
start, make sure the switch is in
the OFF position and the plug is
not connected to the power source
outlet.
1. Lay out desired design, or secure
design to the workpiece (1).
2. Raise the blade guard foot (2) by
loosening the blade guard foot lock
knob (3).
3. Position the workpiece against the
blade and place the blade guard
foot slightly above the top surface
of the workpiece.
4. Secure the blade guard foot (2) by
tightening the blade guard foot lock
knob (3).
5. Remove the workpiece from the
blade prior to turning the scroll saw
ON. Set the variable speed control
knob (4) to the desired speed by
turning the control knob clockwise
or counterclockwise.
CAUTION: In order to avoid
uncontrollable lifting of the
workpiece and to reduce blade
breakage, do not turn saw ON
while the workpiece is against the
blade.
can only remove wood when they
are on the down stroke.
4. There is a learning curve for each
person who wants to use this
saw. During that period of time it
is expected that some blades will
break until you learn how to use
the saw and receive the greatest
benefit from the blades.
5. Best results are achieved when
cutting wood less than one inch
thick.
6. When cutting wood thicker than
one inch, the user must guide the
wood very slowly into the blade and
take extra care not to bend or twist
the blade while cutting in order to
maximize blade life.
7. Teeth on scroll saw blades wear out
and must be replaced frequently
for best cutting results. Scroll saw
blades generally stay sharp for 1/2
to 2 hours of cutting, depending on
material being cut.
8. To get accurate cuts, be prepared
to compensate for the blade’s
tendency to follow the wood grain
as you are cutting.
9. This scroll saw is intended to cut
wood or wood products. Plastics
and non-ferrous metals perform
well on scroll saws that have very
slow speed capability, and should
be lubricated with machine oil or
beeswax.
10. When choosing a blade to use
with your scroll saw, consider very
fine, narrow blades to scroll cut in
thin wood 1/4 in. thick or less. Use
wider blades for thicker materials
but this will reduce the ability to cut
tight curves.
