ELECTRICAL EQUIPMENT INJURY RISKS. You can

be shocked, burned, or killed by touching live

machinery. To reduce this risk, only allow an
electrician or qualified service personnel to
do electrical installation or repair work, and
always disconnect power before accessing or
exposing electrical equipment.

DISCONNECT POWER FIRST. Always disconnect

machine from power supply BEFORE making
adjustments, changing tooling, or servicing
machine. This eliminates the risk of injury
from unintended startup or contact with live
electrical components.

machinery may cause cancer, birth defects,
or long-term respiratory damage. Be aware of
dust hazards associated with each workpiece
material, and always wear a NIOSH-approved
respirator to reduce your risk.

Always wear hearing
protection when operating or observing
loud machinery. Extended exposure to this
noise without hearing protection can cause
permanent hearing loss.

Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys,
wrenches, or any other tools on machine.
Always verify removal before starting!

Only use machine for its
intended purpose—never make modifications
without prior approval from Woodstock
International. Modifying machine or using
it differently than intended will void the
warranty and may result in malfunction or
mechanical failure that leads to serious
personal injury or death!

Keep proper footing and
balance at all times when operating machine.
Do not overreach! Avoid awkward hand
positions that make workpiece control difficult
or increase the risk of accidental injury.

Additional Safety for Scroll Saws

Serious cuts or amputation can occur from contact with the moving saw blade during operation or
if blade breakage occurs. To reduce this risk, anyone operating this machine MUST completely heed
the hazards and warnings below.

SAFETY

HAND PLAC E M E NT. Never position fingers or

hands in line with the blade. If the workpiece
or your hands slip, serious personal injury
could occur.

INTENDED USE. This machine is intended for

cutting natural and man-made wood products,
and laminate covered wood products. This
machine is NOT designed to cut metal, glass,
stone, tile, etc.

BLADE

BLA

BLADE SPEED. Always allow blade to reach full

BLADE CONTROL. To avoid serious personal

CONDITION. Do not operate with dull,

cracked, or badly worn blade. Dull blades
require more effort to perform the cut and
increase the risk of kickback. Inspect blades
for cracks and missing teeth before each use.

DE TENSION. To avoid mishaps that could

result in operator injury, make sure blade
teeth face down toward the table and the
blade is properly tensioned before operating.

speed before starting the cut. Moving the
workpiece into a blade that is not at full
speed could cause the blade to break or grab
the workpiece and draw the operator’s hands
into the blade.

injury, DO NOT attempt to stop or slow the
blade with your hand or the workpiece. Allow
the blade to stop on its own.

BLADE GUARD. When properly adjusted, the

blade guard helps protect the operator’s
hands and fingers from accidental contact
with the moving blade. ONLY operate this
scroll saw with the blade guard in the proper
position. Keep the guard as close as possible
to the workpiece without interfering with the
intended operation.

CUTTING TECHNIQUES. Plan your operation so

the blade always cuts to the outside of the
workpiece. DO NOT back the workpiece away
from the blade while the saw is running,
as this could cause kickback and personal
injuries. If you need to back the workpiece
out of blade, turn scroll saw OFF and wait
for the blade to come to a complete stop.
DO NOT twist or put excessive stress on
the blade or it could damage/break blade.
Instead, use relief cuts for curve cuts that
may twist the blade.

LEAVING WORK AREA. Never leave a machine

running unattended. Allow the scroll saw to
come to a complete stop before you leave it
unattended.

SMALL WORKPIECE HANDLING. If your hands

slip while guiding small workpieces with your
fingers during a cut, amputation or laceration
injuries could occur. Always support/feed the
workpiece with push sticks, jig, vise, or some
type of clamping fixture.

FEED RATE. To avoid the risk of the workpiece

slipping and causing operator injury, always
feed stock evenly and smoothly. DO NOT
force or twist the blade while cutting,
especially when cutting small curves.

CUT-OFF PIECES. Never use your hands to move

cut-offs away from the blade while the saw
is running. If a cut-off becomes trapped
between the blade and table insert, turn the
saw OFF and allow the blade to completely
stop before removing it.

This machine will perform many types of operations
that are beyond the scope of this manual. Many of these
operations can be dangerous or deadly if performed
incorrectly.

The instructions in this section are written with the
understanding that the operator has the necessary
knowledge and skills to operate this machine. If at any
time you are experiencing difficulties performing any
operation, stop using the machine!

The overview below provides the novice machine operator
with a basic understanding of how the machine is used
during operation, so the machine controls/components
discussed later in this manual are easier to understand.
Due to its generic nature, this overview is
to be an instructional guide.

OPERATIONS

General

To reduce your risk of serious injury
or damage to the machine, read this
entire manual BEFORE using machine.

NOT intended

To complete a typical operation, the operator does the
following:

Examines workpiece to make sure it is suitable for

1.

cutting.

If necessary, adjusts table tilt to correct angle of

2.

desired cut.

Loosens hold-down shoe height knob, adjusts blade

3.

guard height to just clear workpiece (no more than

1

⁄4"), then retightens hold-down shoe height knob.

Verifies workpiece can safely pass all the way

4.

through blade without interference from other
objects.

Puts on safety glasses and a respirator.

5.

6. Starts dust collector and turns machine ON.

To reduce the risk of eye injury and
long-term respiratory damage, always
wear safety glasses and a respirator
while operating this machine.

If you are an inexperienced operator,
we strongly recommend that you read
books or trade articles, or seek training
from an experienced operator of this
type of machinery before performing
unfamiliar operations. Above all, safety

must come first!

OPERATIONS

Sets saw blade speed.

7.

8. Holds workpiece firmly and flat against table and

then pushes workpiece into blade at a steady and
controlled rate until cut is complete.

Rotates variable-speed dial to slowest speed, then

9.

turns machine OFF.

Basic Functions of a Scroll Saw

A properly adjusted scroll saw performs many
types of cuts with ease and accuracy. It is
capable of performing these types of cuts:

Straight Cuts

• Miters, angles and compound angles,
ripping, and crosscutting

Irregular Cuts

• Simple and complex curves, duplicate
parts, circles, and beveled curves

Basic Cutting Tips

Basic tips to follow when operating a scroll saw:

• Typically, a scroll saw blade stays sharp

• Best cutting results will be achieved when

being cut.

cutting workpieces less than 1" thick. When
cutting workpieces thicker than 1", move
workpiece through the blade very slowly.

⁄2 hour to 2 hours of use, depending

Workpiece Inspection

Some workpieces are not safe to cut or may
require modification before they can be made
safe to cut.

inspecting all workpieces for the following:

• Material Type: This machine is intended

for cutting natural and man-made wood
products, laminate covered wood products,
and some plastics. Cutting drywall or
cementitious backer board creates
extremely fine dust and may reduce the
life of the bearings. This machine is NOT
designed to cut metal, glass, stone, tile,
etc.; cutting these materials with a scroll
saw may lead to injury.

• Foreign Objects: Nails, staples, dirt,

rocks and other foreign objects are often
embedded in wood. While cutting, these
objects can become dislodged and hit the
operator, cause kickback, or break the
blade, which might then fly apart. Always
visually inspect your workpiece for these
items. If they can't be removed, DO NOT
cut the workpiece.

Before cutting, get in the habit of

• Blades dull much faster when cutting

plywood, hardwoods, and laminates.

• Exerting excessive side pressure on blade

OPERATIONS

greatly increases chance of blade breakage.

• Plan cut before starting curves. Make relief

cuts in waste areas near tight inside curves
or leave tight inside curves for a second
pass to minimize backing out. Cut sharp
outside curves by cutting past curve and
looping around to cut from different angle.

• When approaching tight radius, slow down

feed rate, but don’t stop. Give teeth time
to make cut. Forcing workpiece through
curve will cause blade to twist or break.

• If cut produces waste in curve’s interior,

turn power OFF and wait until all motion
stops before removing waste.

• Scroll saw blades have a tendency to drift.

This is compensated by adjusting the feed
direction.

• Large/Loose Knots: Loose knots can

become dislodged during the cutting
operation. Large knots can cause kickback
and machine damage. Choose workpieces
that do not have large/loose knots or plan
ahead to avoid cutting through them.

• Wet or "Green" Stock: Cutting wood

with a moisture content over 20% causes
unnecessary wear on the blades, increases
the risk of kickback, yields poor results.

• Excessive Warping: Workpieces with

excessive cupping, bowing, or twisting are
dangerous to cut because they are unstable
and often unpredictable when being
cut. DO NOT use workpieces with these
characteristics!

• Minor Warping: Workpieces with slight

cupping can be safely supported if the
cupped side faces the table. On the
contrary, a workpiece supported on the
bowed side will rock during a cut and could
cause kickback or severe injury.

Hold-Down Shoe

& Blade Guard

The hold-down shoe and blade guard are mounted on the
same rod and are adjusted together. The hold-down shoe
keeps the workpiece from raising up from the force of the
moving blade. The blade guard helps prevent debris from
flying at the operator and acts as a barrier between the
blade and the operator's hands, thus reducing the risk of
accidental contact.

Item(s)

Hex Wrench 4mm

To adjust hold-down shoe and blade guard, do these
steps:

1.

2. Loosen hold-down shoe lock knob and shoe screw

Chip Blower

The chip blower moves air across the blade to keep wood
debris away from the line of the cut. This makes it easier
to follow your cutting lines with accuracy.

Standard Scroll Cuts

For standard scroll cutting, follow the pattern line on the
workpiece by pushing and turning the workpiece at the
same time, which allows the kerf of the cut to make way
for the turn.

DO NOT turn the workpiece without pushing it through
the blade at the same time; otherwise, the blade could
twist and break. See
standard scroll cutting.

Blade Tension

If the blade is not tensioned enough, it will drift while
cutting, making it difficult to follow your cutting lines. If
the blade is tensioned too tightly, it can break or cause
damage to the saw.

To make a bevel cut, do these steps:

1. Draw your cutting path pattern on workpiece.

2. Adjust table to desired angle.

3. Turn machine ON, then feed workpiece slowly

Inside Cuts

Inside cuts can be easily made with your scroll saw by
threading the blade through a hole drilled in the workpiece.
The flex-shaft rotary tool on the W1872 can be used to
assist with this drilling.

To make an inside cut, do these steps:

1. Drill a 1⁄4" hole in the workpiece inside scrap area of

internal cut.

DISCONNECT MACHINE FROM POWER!

2.

3. Remove blade from saw.

4. Insert blade through previously drilled hole in

workpiece (see Figure 23).

Note: If using a plain-end blade, remove one blade

Blade Speed

The variable-speed dial shown in Figure 24 adjusts the
blade speed between 550–1650 SPM (strokes per minute).

To reduce the risk of injury from unexpected fast speed
at startup, always rotate the variable-speed dial to its
slowest setting when starting/stopping the scroll saw.
