ADDITIONAL SAFETY RULES FOR SCROLL SAWS
1. WARNING: Do not operate your scroll saw until it is
completely assembled and installed according to the
instructions.
2. IF YOU ARE NOT thoroughly familiar with the operation of scroll saws, obtqin advice from your supervisor,
instructor or other qualified person.
3. YOUR SCROLL
SAW
MUST be securely fastened
to
a stand or workbench. If there
is
any tendency for the
stand or workbench
to
move during operation, the stand
or workbench MUST be fastened
to
the floor.
4. THIS SCROLL
SAW
is intended for indoor use only.
5. MAKE SURE blade
is
properly tensioned before
operating saw.
6. TO AVOID blade breakage
ALWAYS
adjust blade
tension correctly.
7. MAKE SURE the blade teeth point downward toward
the table.
8. NEVER turn the saw
"ON"
before clearing the table
of all objects (tools, scraps of wood, etc.).
9.
DO
NOT cut material that is too small to
be
safely
supported.
10. AVOID awkward hand positions where a sudden slip
could cause a hand to move into the blade.
11.
ALWAYS
keep hands and fingers away from the
blade.
12.
ALWAYS
adjust holddown foot for each new
operation.
13. DO NOT USE dull or bent blades.
14. DO NOT attempt
to
saw material that does not have
a flat surface, unless a suitable support is used.
15.
MAKE
"relief"
cuts before cutting long curves.
16. NEVER attempt to cut a curve that is too tight for
the blade being used.
17. WHEN backing a blade out of a workpiece, the blade
may bind in the saw kerf. This is usually caused by
sawdust
in
the kerf. If this happens, turn
"OFF"
the switch
and remove plug from power source outlet. Wedge open
the kerf and back blade out of the workpiece.
4
18.
ALWAYS
hold the work firmly against the table.
19. DO NOT feed the material too fast while cutting.
Only feed the material fast enough so that the blade will
cut.
20. NEVER start the Scroll Saw with the stock pressed
against the blade.
21. WHEN cutting a large workpiece
MAKE
SURE the
material is supported at table height.
22. USE CAUTION when cutting material which
is
ir-
regular
in
cross section, which could pinch the blade
before the cut is completed. A piece of moulding, for
example, must lay flat on the table and not be permitted
to
rock while being cut.
23. USE CAUTION when cutting round material such
as
dowel rods or tubing. They have a tendency
to
roll while
being cut, causing the blade to
"bite."
Use a V-block to
control the piece.
24.
ALWAYS
release blade tension before loosening the
blade holder screw.
25. MAKE CERTAIN table tilting lock
is
tightened before
starting the machine.
26. NEVER reach under the table while the machine is
running.
27. NEVER perform layout, assembly or set-up work on
the table while the saw
is
operating.
28.
ALWAYS
STOP the saw before removing scrap
pieces from the table.
29. SHOULD any part of your scroll saw be missing,
damaged, or fail
in
any way, or any electrical component
fail
to
perform properly, shut off switch and remove plug
from power supply outlet. Replace missing, damaged or
failed parts before resuming operation.

CONNECTING SCROLL SAW TO POWER SOURCE
POWER CONNECTIONS
A separate electrical circuit should be used for your tools. This circuit should not be less than
#12 wire and should be protected with a 20
Amp
time lag fuse. If an extension cord is used, use
only 3-wire extension cords which have 3-prong grounding type plugs and 3-pole receptacles which
accept the tools plug. For distances up to 100 feet use #12 wire. For distances up to 150 feet
use #10 wire. Have a certified electrician replace or repair damaged or worn cord immediately.
Before connecting the motor to the power line, make sure the switch
is
in the
"OFF"
position
and be sure that the electric current
is
of the same characteristics
as
stamped on motor nameplate.
All line connections should make good contact. Running on low voltage will injure the motor.

TABLE
INSERT
The
table insert (A) can be
assembled
to the
saw
table with the
opening
in the insert
pointing
to the front
of
the table, as
shown
in Fig. 14,
or
to the right of the table, as
shown
in Fig. 15.
With
the table in the level position, 90
degrees
to the blade, the insert (A)
should
be
positioned
as
shown
in Fig. 14.
This
allows for the blade to be pivoted forward
after
it is
unclamped
from
the top blade holder,
enabling
you to
quickly
insert the blade into the next hole in a pattern when
doing
inside
cutting, as you will see later in this manual.
When
tilting the table for bevel
cutting
operations, the insert (A)
should
be
positioned
as
shown
in Fig.
15.
This
allows
clearance
for the blade
when
tilting the table.
A table insert
blank
(B) Fig. 16, is
supplied
as
standard
equipment
with
your
scroll
saw
and can be used
when
cutting
very small
workpieces
to
give
added
support
to
the bottom of the
workpiece.
Simply
cut
a slot into the
blank
and replace the
standard
insert
(A)
with the
blank
(B).
The
slot
cut
into the
blank
(B) will
only
be
as
wide
as
the blade
giving
maximum
support
to the
bottom
of
the
workpiece.

BLADE BREAKAGE
Blade
breakage
is
usually
caused
by
one
or
more
of
the
following:
1.
Bending
the blade
during
installation.
2.
Improper
blade tension.
3.
Improper
blade
selection
for the
work
being
cut.
4. Forcing the
work
into the blade too rapidly.
5.
Cutting too
sharp

6.
Improper
blade speed.

ADJUSTING BLADE TENSION
Tension
is
applied
to
the
blade
when
the
blade
tension
lever (A) is in the rear position, as
shown
in Fig. 17.
When
the
lever
(A) is
moved
forward, as
shown
in Fig. 18, blade
tension
is released.
To increase blade tension, turn knob (8) Fig. 18, clockwise
and to decrease blade tension, turn knob
(8) counterclock-
wise.
When
adjusting
blade
tension,
lever
(A)
should
be
in the forward position, as
shown
in Fig. 18.
NOTE:
It
is
necessary
to
adjust
the
blade
tension
knob (8)
only
when
the
blade
is
removed
from both
upper
and
lower
blade
holders and a
new
or
different
type of blade is
assembled
to
the
holders. It is not
necessary
to
adjust
blade
tension
when the blade is removed and replaced
in
only the
upper
blade
holder
as in
performing
inside
CUlling
operations.
Adjusting
the
blade
for
proper
tension
is
usually
accomp-
lished
by trial and error;
however, a good
method
to
use
is to
pluck
the
rear
of
the
blade,
like a guitar
string
after
the
tension
lever
(A) Fig. 18, is
moved
to
the
rear. A
high
pitched tone
of
the blade should be heard
and
this usually
indicates
proper
tension.
Finer
blades
require
more
ten-
sioning
(a
higher
pitched
sound)
while
thicker
blades
require less tension.
TILTING THE TABLE
The
table
on
your
scroll
saw
can
be
tilted
45
degrees
to
the left for bevel CUlling operations by loosening table lock
handle
(A) Fig. 19, tilt
the
table
to the
desired
angle
and
tighten
lock
handle
(A).
NOTE:
The
table
lock
handle
(A)
can be repositioned by
removing
screw
(0)
and
removing
and
repositioning
handle
(A) on the
hex
rod located
underneath
the
hub
of the
handle.
When
bevel CUlling,
the
holddown
(8)
Fig. 20, can be
adjusted
to lay flat on
the
stock
by
loosening
screw
(C)
and tilting
the
holddown
(8)
accordingly.
Then
tighten
screw
(C).
If the
workpiece
is too thick,
causing
the
stock
to
contact
the holddown arm, the complete holddown assembly
must
be
removed,
since
thick
stock
is
heavy
enough
to resist
lifting
off
the
table
during
the
blade
up
stroke.

OPERATION
Fig. 26
FOLLOWING A LINE
Fig. 26 illustrates a typical scroll saw operation being made following the outside line on a
pattern. With your scroll saw you should be able to cut a straight or curved line with ease. Most
beginners will experience blade wandering; however, they eventually learn to control it
as
they
become more familiar with the machine. Use scrap material to practice cuts before starting
a project. This enables you to develop your own way of cutting and you will find out what you
can and cannot do with your saw. Always hold the work firmly against the table and do not
feed the workpiece too fast while cutting. Feed the workpiece only fast enough so that the blade
will cut. Scroll saws cut faster across the grain than they do with the grain. Allow for this tendency
when cutting patterns that shift rather quickly from with-the-grain cuts to cross-grain cuts. Make
"relief"
cuts before cutting long curves and never attempt to cut a curve that
is
too tight for
the blade being used.
12
Page 13
INSIDE CUTTING
Inside cutting
is
where the blade must be threaded through a hole
in
the workpiece. The Delta
20"
Scroll Saw has
the capability
of
performing this operation quickly and easily as follows:
Fig. 27
1.
Let's assume you are performing
an
inside cutting operation on a project, similar to the one shown
in
Fig. 27, that
has numerous inside cuts to be made. This can be accomplished quickly with the Delta saw.
In
Fig. 27, the operator
has just completed one of the inside cuts and must move to the next hole.
2.
Loosen lock handle (A) Fig. 28, and raise holddown bar (B). Release blade tension by moving tension lever
(C)
forward and loosen upper blade holder screw using the quickset blade changing wrench (D). Move the blade forward
and insert it into the next hole
in

BRUSH INSPECTION
AND REPLACEMENT
CAUTION: BEFORE INSPECTING THE BRUSHES,
DISCONNECT THE MACHINE FROM THE POWER
SOURCE.
Brush life varies. It
depends
on the load on the motor.
Check the brushes after the first 50 hours of use for a new
machine
or after a new set of brushes has been installed.
After the first check,
examine
them
after
about
10
hours
of
use until
such
time that
replacement
is necessary.

The brush holders,
one
of
which
is shown at (A) Fig. 34,
are located on the
motor
housing opposite each other.
Fig.
35, illustrates one of the brushes removed for inspec-
tion. When the carbon (B) on either brush is worn to
3/16"
in length or if
either
spring (C) or
shunt
wire is burned or
damaged in any way, replace both brushes. If the brushes
are found serviceable after removing, reinstall them in the
same position as removed.
