STACK CUTTING
See Figure 19.
After becoming well acquainted with your saw through
practice and experience, you may wish to try stack
cutting. Stack cutting may be used when several
identical shapes need to be cut. Several pieces of
wood may be stacked on top and secured to each
other before cutting. The wood pieces may be joined
together by placing double sided tape between each
piece or by wrapping masking tape around the
corners or ends of the stacked wood. You must attach
the stacked pieces of wood to each other so they will
move on the table as a single piece of material.
_I, .WARNING:. To avoid possible, serious personal
injury, do not cut more than one loose piece of
material at a time.

CHOICE OF BLADE AND SPEED
The scroll saw accepts a wide variety of blade widths and thicknesses for cutting wood and other fibrous materi-
als. Your saw uses 5 inch long blades of either the pin end or the plain end style. The blade width and thickness
and the number of teeth per inch to use are determined by the type of material and the size of the radius being
cut. A full selection of scroll saw blades are available through Sears Retail Stores.
Note: As a general rule, always select narrow blades for intricate curve cutting, and wide blades for straight and
large curve cutting.

BEFORE EACH USE:
INSPECT YOUR SAW. Disconnect the saw. To
avoid injury from accidental starting, turn the
switch OFF and unplug the saw before changing
the setup or removing covers, guards, or blade.
INSPECT YOUR WORKPIECE. Make sure there
are no nails or foreign objects in the workpiece to
be cut.
USE EXTRA CAUTION WITH LARGE, VERY
SMALL, OR AWKWARD WORKPIECES.
Never use this tool to cut pieces too small to hold
by hand.
Always use extra supports (tables, saw horses,
blocks, etc.) for any workpiece large enough to
tip when not held down to the table top.
Never use another person as a substitute for a
table extension, or as additional support for a
workpiece or to help feed, support, or pull the
workpiece.
When cutting an irregularly shaped workpiece,
plan your work so it will not pinch the blade. A
piece of molding, for example, must lay flat or be
held by a fixture or jig that will not let it twist,
rock, or slip while being cut.
