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 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.

BLADE TENSION. To avoid mishaps that could

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

BLADE SPEED. Always allow the blade to come

to full speed before starting the cut. Moving
the workpiece against 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.

BLADE CONTROL. To avoid serious personal

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

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 sawing small curves.

BLADE GUARD. The blade guard protects the

operator’s hands and fingers from 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,
which could cause kickback and personal
injuries. If you need to back the workpiece
out, turn the scroll saw OFF and wait for the
blade to come to a complete stop. DO NOT
twist or put excessive stress on the blade
that could damage it. 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 holding 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.

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.

Model W1870 (For Machines Mfd. Since 03/19)

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but
it will take a little time to clean.

Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper
care of your machine's unpainted surfaces.

There are many ways to remove this rust
preventative, but the following steps work well
in a wide variety of situations. Always follow the
manufacturer’s instructions with any cleaning
product you use and make sure you work in a
well-ventilated area to minimize exposure to
toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

1.

3.

4.

Refer to the Machine Specifications for the
weight and footprint specifications of your
machine. Some workbenches may require
additional reinforcement to support the weight
of the machine and workpiece materials.

Consider anticipated workpiece sizes and
additional space needed for auxiliary stands,
work tables, or other machinery when
establishing a location for this machine in the
shop. Below is the minimum amount of space
needed for the machine.

Put on safety glasses.

Coat the rust preventative with a liberal

amount of cleaner/degreaser, then let it
soak for 5–10 minutes.

Wipe off the surfaces. If your cleaner/

degreaser is effective, the rust
preventative will wipe off easily. If you
have a plastic paint scraper, scrape off as
much as you can first, then wipe off the
rest with the rag.

Repeat Steps 2–3 as necessary until clean,

then coat all unpainted surfaces with a
quality metal protectant to prevent rust.

INJURY HAZARD! Untrained
users can injure themselves
with this machine. Restrict
access to machine when
you are away, especially if
it is installed where chil­dren are present.

Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.

Bench Mounting

The base of this machine has mounting holes that allow it
to be fastened to a workbench or other mounting surface
to prevent it from moving during operation and causing
accidental injury or damage.

The strongest mounting option is a "Through Mount" (see
example) where holes are drilled all the way through the
workbench—and hex bolts, washers, and hex nuts are
used to secure the machine in place.

Another option is a "Direct Mount" (see example) where
the machine is secured directly to the workbench with lag
screws and washers.

Do not confuse this CFM recommendation with the rating
of the dust collector. To determine the CFM at the dust
port, you must consider these variables: (1) CFM rating of
the dust collector, (2) hose type and length between the
dust collector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines throughout
the system. Explaining how to calculate these variables
is beyond the scope of this manual. Consult an expert or
purchase a good dust collection “how-to” book.

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:

1. Examines workpiece to make sure it is suitable for
cutting.

2. Adjusts table tilt, if necessary, to correct angle of
desired cut.

3. Loosens hold-down shoe height knob, adjusts blade
guard height to just clear the workpiece (no more

1

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

than
knob.

4. Checks to make sure workpiece can safely pass all
the way through blade without interference from
other objects.

5. Puts on safety glasses and respirator.

6. Starts dust collector and turns machine ON.

7. Holds workpiece firmly and flat against table and

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

8. Rotates variable-speed dial to slowest speed, then
turns machine OFF.

-19-

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

Model W1870 (For Machines Mfd. Since 03/19)

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

on how blade is used and type of material
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. Before cutting, get in the habit of

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.

• 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.

Model W1870 (For Machines Mfd. Since 03/19)

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) Needed Qty

Hex Wrench 4mm ...............................................1

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

1. DISCONNECT MACHINE FROM POWER!

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

shown in Figure 17.

3. Adjust shoe so it is no more than
workpiece.

Note: When tilting table for your cutting operation,

adjust shoe so it remains parallel with table.

OPERATIONS

4. Lower blade guard over shoe.

5. Re-tighten hold-down height knob and shoe screw,

then verify workpiece moves smoothly under shoe.

Air Nozzle

The air nozzle blows air at 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 Figures 18–19 for examples of
standard scroll cutting.

Figure 18. Example of making straight cut.

Figure 19. Example of making curved cut.

-21-

Blade Tension

Adjust blade tension using the knob shown in Figure 20.
Turn the blade tension knob clockwise to increase the
blade tension and counterclockwise to decrease it.

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 check/adjust blade tension, do these steps:

1. DISCONNECT MACHINE FROM POWER!

2. Pivot blade guard up.

3. Pinch blade and move it side to side with light

pressure to check tension. When properly tensioned,
blade will deflect only slightly when moved, and
ends will remain firmly in position.

Blade Tension Knob

Figure 20. Location of blade tension knob.

4. Tighten/loosen blade as necessary and pivot blade

guard down. Perform a test cut on a scrap piece
of wood and repeat this entire procedure if further
adjustments are necessary.

Bevel Cuts

Bevel cuts can be used for miters, cope joints, and
making relief or recessed projects.

OPERATIONS

To make a bevel cut, do these steps:

1. Draw your pattern as described in the previous

sections.

2. Adjust table to desired angle.

3. Turn machine ON, feed work piece slowly and evenly
into blade, remembering not to force workpiece (see
Figure 21).

4. Turn machine OFF, then wait until blade stops

before removing waste near blade.

Model W1870 (For Machines Mfd. Since 03/19)

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 W1870 can be used to
assist with drilling.

To make an inside cut, do these steps:

1

1. Drill a
internal cut.

2. DISCONNECT MACHINE FROM POWER!

3. Remove blade from saw.

4. Insert blade through previously drilled hole in

workpiece (see Figure 22).

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

adapter to allow the blade to be inserted through
the workpiece, then re-install the adapter on the
blade.

Blade Speed

The variable-speed dial shown in Figure 23 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.

Blade Selection
