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.

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.

Not Recommended

 

 

 

 

 

 

 

 

 

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.

ALWAYS USE SAFETY GLASSES. 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 performance. 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 TOOL. 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. A guard 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

MATERIAL HOLD-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.

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 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. 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 manner 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).

Accessories

Use only 5" plain end and pin scroll saw blades. Recommended accessories for use with your tool are available at extra cost from your local dealer or authorized service center. If you need assistance in locating any accessory for your tool, please call:

1-800-54-HOW-TO (544-6986).

CAUTION: The use of any other accessory not recommended for use with this tool could be hazardous.

Maintenance

Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. Dry table thoroughly to prevent rust.

IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers or other qualified service personnel, always using identical replacement parts.
