Motor
Be sure the power supply agrees with nameplate marking. 120 Volts AC only means your tool
will operate on standard 60 Hz household power. Do not operate AC tools on DC. A rating of
120 volts AC/DC means that your tool will operate on standard 60 Hz AC or DC power. This
information is printed on the nameplate. Lower voltage will cause loss of power and can result
in over-heating. All Black & Decker tools are factory-tested; if this tool does not operate, check
the power supply.
Unpacking Your Saw
Check the contents of your scroll saw carton to make sure that you have received all parts. In
addition to this instruction manual, the carton should contain one No. BT4000 scroll saw and
the following:
- (12) assorted blades (1 already installed on unit)
- (1) zero clearance table insert
- (1) pattern book / helpful hints
- (3) rubber mounting feet
Mounting
Three holes are provided in the base of the scroll saw to facilitate mounting to a table or
bench (Figure 1). Place three rubber mounting feet from hardware bag into the three mount-
ing holes. Always mount your saw firmly to prevent movement. Do not over tighten mounting
bolts. Leave some cushion in the rubber feet for absorbing noise and vibration.
Aligning the Blade With the table Top
This is most easily accomplished with a carpenter's tri-square. Begin by installing a blade in
the saw. Next, place the tri-square on the table top, close to the blade. Observe the align-
ment of the blade to the edge of the square. The blade should be vertically parallel to the tri-
square edge. If it is not, you need to adjust the zero degree stop as described in the follow-
ing paragraph.
Adjusting the Zero Degree Stop
The zero degree stop is located on top of the motor housing on the right side of the saw
below the table (Figure 6). The stop is preset at the factory to have the table rest at 0˚. To
adjust the zero degree stop, tilt the table to 45˚. Loosen the nut, located at the bottom of the
bolt. The bolt can then be turned to correctly align the table at 0˚. Tilt the table to the right
until it stops on the bolt. Re-check the alignment of the blade with the table top. If the align-
ment is correct, tighten the nut finger tight.
To allow the table to tilt 1˚ or 2˚ to the right, turn the zero degree stop completely clockwise.
Installing the Blade
BEFORE INSTALLING A BLADE, UNPLUG THE SCROLL SAW.
The blade is held in place by the thumbscrew blade clamps attached to the top and bottom
arms of the scroll saw (Figure 2).
Before installing a blade, make sure the blade tension lever is rotated upward as shown in
Figure 3. Remove the table insert and loosen, but do not unscrew, the top and bottom thumb-
screws (Figure 2). Thread the blade through the hole in table, with the teeth facing toward
the front of the saw. NOTE: Scroll saws cut on the downstroke, so it is essential that teeth
face forward and down.
Insert the blade into the bottom blade clamp and securely tighten the thumbscrew. Reinstall
table insert. Next, insert the top of the blade into the top blade clamp and securely tighten
the top thumbscrew.
Properly adjust the tension of the blade before operating your scroll saw. (See: Blade Tension
Lever section of this manual.)
Blade Tension Lever
Move the blade tension lever (Figure 3) downward to tension the blade.
NOTE: The lever should move downward with a steady even pressure. The blade is too tight
if excessive pressure is needed.
TO FINE ADJUST THE TENSION ON THE BLADE FOLLOW THE STEPS
BELOW.
1.) To decrease tension, rotate the tension lever counterclockwise 1 or 2 turns.
2.) If the blade is too loose the tension can be increased by leaving the lever in the down
position and turning it clockwise until you feel the tension increase on the blade.
The proper degree of tension varies with different blade sizes. If you are frequently breaking
blades, decrease tension on the blade.
As you become more accustomed to operating your scroll saw, you will become more proficient
in fine-tuning blade tension. Practice on scrap material when possible.
Remove the blade or release tension on the blade when not using your scroll saw for an
extended period. Blade tension can be removed by flipping the blade tension lever up. Be sure
to place the blade tension lever in its downward position again before turning saw on.
Material Hold-down / Guard
The material hold-down (Figure 4) should contact the surface of the workpiece. To adjust the
material hold-down / guard, loosen the thumbscrew (Figure 4) and move the rod up or down.
The material hold-down / guard must be beveled when the table is beveled. To bevel the
material hold-down / guard, loosen the thumbscrew shown in Figure 4 and bevel the mater-
ial hold-down / guard until it is parallel to the table. Retighten the material hold-down / guard
before cutting.
Your scroll saw has a maximum thickness capacity of 2" at 0˚. Do not cut material thicker
than 2".
CAUTION: NEVER remove the material hold-down since it also functions as a
barrier between fingers and blade. This is especially important when cutting metals; sharp
edges may be present
Air Hose
Your scroll saw features an adjustable air hose to keep your work area free from dust and
debris. Be sure to position the air hose properly: it should blow saw dust away from the oper-
ator.
On/Off Switch
To turn the scroll saw on, pull up on the switch shown in Figure 5. To turn the tool off, push
down on the switch. A slot is provided for insertion of a padlock to lock the saw off (Figure 5).
NOTE: The pad lock shackle diameter should be between 3/16" and 7/32".

Speed Control Knob
Your scroll saw features a variable speed control, from 400 to 1,700 strokes per minute. To
operate the variable speed feature, turn the speed control knob (Figure 5).
To increase the speed, turn the knob clockwise. The numbers on the speed control knob
represent speed ranges. 1 is the minimum speed, 5 is the maximum speed.
Slower speeds are recommended for metals, plastics, harder woods and very thin materials.
Sawing
Hold material firmly against table. Always feed material toward the blade. Feed the workpiece
fast enough to allow the blade to cut, but do not force material into the blade too quickly.
CAUTION: The scroll saw should be used to cut wood, wood-like products, plastics
and nonferrous metals (aluminum, copper, brass etc.) only. DO NOT use for cutting ferrous
metals such as iron and steel. Note that when cutting nonferrous metals, the hot metal
shavings can cause a fire when coming in contact with sawdust.
When sawing nonferrous metals:
• Vacuum all sawdust from inside and under the saw before use.
• Vacuum all traces of metal dust (after it has completely cooled) from inside and under the
saw before using saw to cut wood, etc.
Sawdust Collection Port
A sawdust collection port is located on the side of the saw as shown in Figure 6. To use the
port, attach a 1-1/4" vac hose to the opening.
NOTE: Through normal use sawdust accumulates under the saw. Frequently clean sawdust
from under the unit to prevent the linkage from binding, which could overload and damage the
motor. A hole can also be cut in the bench or stand below the lower blade clamp in such a man-
ner that will not allow sawdust to accumulate under the tool.
Beveling
The table of your scroll saw bevels 47° left and -2° right. A stop is set at 0°. To bevel the scroll
saw table, loosen the bevel lock knob (Figure 7), and bevel the table to the desired setting,
indicated by the bevel pointer.
Fretwork
INSIDE CUTS
Your scroll saw is ideal for making inside cuts for detail work. To make an inside cut:
1. Drill a pilot hole in your workpiece.
2. Make sure the blade tension lever is rotated upward to remove tension.
3. Loosen the top blade clamp knob.
4. Leaving the blade held in place by the bottom blade clamp, thread the saw blade through
the pilot hole in your workpiece and reattach the blade by tightening the top blade clamp
knob.
5. Readjust the blade tension and begin the inside cut.
Zero Clearance Table Insert
A Zero Clearance Table Insert (solid orange plastic circular disk) is included with the scroll
saw. It is designed to give maximum support to the underside of the workpiece and to prevent
small workpieces from falling into the saw.
When working with small workpieces with the table set at 0˚, remove the standard insert and
replace with the Zero Clearance Table Insert.
Before using, drill a hole in the center of the disk for the blade. You should drill the smallest
hole possible that will allow the blade to move freely.
Table
Keep the table clean and free from oil, grease and pitch. Treat the table with paste wax to
help maintain its smooth finish.
Blade Storage Tray
A convenient storage tray for blades is built into the top of the saw (Figure 5).

GUIDE D'UTILISATION
Mise à la terre
En cas de mauvais fonctionnement ou de bris de l'outil, la mise à la terre procure un chemin
de moindre résistance au courant électrique afin de minimiser les risques de secousses élec-
triques. Le cordon de l'outil comporte un conducteur de terre et une fiche de mise à la terre.
La fiche doit être branchée dans une prise de machine bien installée et mise à la terre con-
formément aux lois et règlements locaux. Ne pas modifier la fiche fournie. Lorsque la fiche
n'entre pas dans la prise, demander à un électricien qualifié d'installer une prise appropriée.
La mauvaise connexion du conducteur de terre de l'outil présente des risques de secousses
électriques. Le conducteur dont l'isolant est vert ou vert avec des lignes jaunes constitue la
mise à la terre. En cas de réparation ou de remplacement du cordon ou de la fiche, ne pas
relier le conducteur de terre à une borne sous tension.
Consulter un électricien qualifié ou le personnel des centres de service an cas d'incom-
préhension des instructions relatives à la mise à la terre ou en cas de doute quant à la mise
à la terre de l'outil.
