Black & Decker BT4000, 398178-00 User Manual

WARNING: For your own safety read instruction manual before operating tool.

Grounding Instructions

In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded in accordance with all local
codes and ordinances. Do not modify plug provided—if it will not fit the outlet, have the proper
outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-grounding conductor to a live
terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles
that accept the tool’s plug.

Repair or replace damaged or worn cords immediately.
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in

Figure A. The tool has a grounding plug that looks like the plug illustrated in Figure A. A
temporary adapter, which looks the adapter illustrated in Figures B and C, may be used to
connect this plug to a 2-pole receptacle as shown in Figure B if a properly grounded outlet is
not available. The temporary adapter should be used only until a properly grounded outlet
can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like,
extending from the adapter must be connected to a permanent ground such as a properly
grounded outlet box.

WARNING:Read and understand all instructions. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious personal injury.

Important Safety Instructions

• KEEP GUARDS IN PLACE and in working order.

• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys
and adjusting wrenches are removed from tool before turning it on.

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.

• DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet
locations, or expose them to rain. Keep work area well lighted.

• KEEP CHILDREN AWAY.All visitors should be kept safe distance from work area.

• MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter
keys.

• DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was
designed.

• USE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not designed.

• USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
When using and extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. The following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.

• OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension
cords intended for use outdoors and so marked.

• WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets,
or other jewelry which may get caught in moving parts. Nonslip footwear is recommended.
Wear protective hair covering to contain long hair.

• ALWA YS USE SAFETYGLASSES.Also use face or dust mask if cutting operation is dusty .
Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.

• DON’T OVERREACH. Keep proper footing and balance at all times.

• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest per-
formance. Follow instructions for changing accessories.

• DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits,
cutters, and the like.

• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position
before plugging in.

• USE RECOMMENDED ACCESSORIES. Consult the instruction manual for recommended
accessories. The use of improper accessories may cause risk of injury to persons.

• NEVER STAND ON T OOL. Serious injury could occur if the tool is tipped or if the cutting tool
is unintentionally contacted.

• CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is
damaged should be carefully checked to determine that it will operate properly and perform
its intended function–check for alignment of moving parts, binding of moving parts, breakage
of parts, mounting, and any other conditions that may affect its operation. Aguard or other
part that is damaged should be properly repaired or replaced.

• NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.

ADDITIONAL SAFETY RULES FOR SCROLL SAWS

• MATERIALHOLD-DOWN must be properly set according to these instructions and remain
in position during use.

• NEVER reach under the table when operating or make any adjustments when it is running.

• SECURE saw to work bench or stand with clamps or mounting hardware. Secure work
bench or stand to floor.

• DO NOT use the upper arm as a lifting point.

• MAKE SURE blade tension is properly adjusted.

• AVOID awkward hand positions where a sudden slip could cause a hand to move into a saw
blade or cutting tool. DO NOT PLACE FINGERS OR HANDS IN PATH OF THE SAW
BLADE.

• WHEN REMOVING short workpieces, or cleaning up around the table, be sure the saw is in
the OFF position and blade has stopped moving.

• NEVER turn the saw ON before clearing the table of all tools, wood scraps, etc., except the
workpiece and related feed or support devices for the operation planned.

• CHECK for proper blade size and type.

• DO NOT attempt to saw stock that does not have a flat surface, unless a suitable support is
used.

• HOLD material firmly against table and feed into blade teeth at a moderate speed.

• TURN OFF motor if the material resists being backed out of an uncompleted cut. Use
appropriate speed for applications.

• MAKE “relief” cuts before cutting long curves.

• USE a dust mask and safety glasses when sawing.

• KEEP GUARDS in place and working order.

• MAKE SURE your fingers do not contact the terminals of the power cord when installing or
removing the plug to or from the line power source.

• NEVER overfeed or force work into the blade.

• WARNING: Do not allow familiarity (gained from frequent use of your saw) to replace
following safety rules. Always remember that a careless fraction of a second is sufficient to
inflict severe injury.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or other repro­ductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber. (CCA)
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.

KEY INFORMATION YOU SHOULD KNOW:

• For best performance, secure saw to work bench or stand with clamps or mounting

hardware. Secure work bench or stand to floor.

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 Y our 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 mount­ing 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 align­ment of the blade to the edge of the square. The blade should be vertically parallel to the tri­square edge. If it is not, you need to adjust the zero degree stop as described in the follow­ing 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 align­ment 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 thumb­screws (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 mater­ial 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 oper­ator.

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. Aslot 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”.

GUIDE D’UTILISATION

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:

• V acuum 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 man­ner that will not allow sawdust to accumulate under the tool.

Beveling

The table of your scroll saw bevels 47° left and -2° right. Astop 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

Y our 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).

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 con­formément 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’incom­préhension des instructions relatives à la mise à la terre ou en cas de doute quant à la mise
à la terre de l’outil.
