POWER CONNECTIONS

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the "OFF" position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.

Do not expose the machine to rain or operate the machine in damp locations.

MOTOR SPECIFICATIONS

Your machine is wired for 120V, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the "OFF" position.

GROUNDING INSTRUCTIONS

This machine must be grounded while in use to protect the operator from electric shock.

1. All grounded, cord-connected machines:

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 machine is equipped with an electric cord having an equipment-grounding conductor and a 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 the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conduc-tor can result in 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 machine is properly grounded. Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that

accept the machine’s plug, as shown in Fig. A. Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less

than 150 volts:

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the

machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks

like the adapter illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor receptacle as

shown in Fig. 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. Whenever the adapter is used, it must be held in place with a metal screw.

NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

In all cases, make certain that the receptacle in question is properly grounded. If you are not sure,

have a qualified electrician check the receptacle.

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 or D-2, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

OPERATION

OPERATIONAL CONTROLS AND ADJUSTMENTS

STARTING AND STOPPING SCROLL SAW

Make sure that the switch is in the "OFF" position before plugging cord into outlet. Do not touch the plug’s metal prongs when unplugging or plugging in

the cord.

The on/off switch (A) Fig. 5 is located on the right side of the scroll saw base. To turn the machine "ON", move the switch up to the "ON" position. To turn the machine "OFF", move the switch (A) down to the "OFF" position.

LOCKING SWITCH IN THE "OFF" POSITION

IMPORTANT: When the machine is not in use, the switch should be locked in the "OFF" position to prevent unauthorized use. To lock the machine, grasp the switch toggle (B) and pull it out of the switch (Fig. 6). With

the switch toggle (B) removed, the switch will not operate. However, should the switch toggle be removed while the saw is running, the machine can be turned "OFF," but cannot be restarted without re-inserting the switch toggle (B).

In the event of a power outage (such as a breaker or fuse trip), always move the switch to the "OFF" position until the main power is restored. An accidental start-up can cause injury.

Fig. 5

Fig. 6

VARIABLE SPEED SWITCH

The scroll saw is equipped with a variable speed control (B) Fig. 5. The variable speed range is 600 to 1650 strokes per minute. When the variable speed knob (B) Fig. 5, is rotated all the way to the left (counterclockwise) the speed will be 600 strokes per minute. To increase the speed, rotate knob (B) to the right (clockwise) until the desired speed is obtained. When the knob (B) is rotated all the way to the right (clockwise) the speed will be 1650 strokes per minute.

ADJUSTING BLADE TENSION

Disconnect machine from power source.

Tension is applied to the blade when the blade tension lever (A) Fig. 7, has been adjusted and is in the vertical position as shown. When the blade tension lever (A) is moved to the horizontal position, as shown in Fig. 8, blade tension is released.

To adjust blade tension, position lever (A) in the vertical position, as shown in Fig. 7. To increase tension, turn lever (A) clockwise and to decrease tension turn lever (A) counterclockwise. When adjusting tension, turn lever onequarter of a turn at a time. NOTE: It is necessary to adjust the blade tension only when the blade is removed from both the upper and lower blade holders and a new or different type of blade is used. It is not necessary to adjust blade tension when the blade is removed and replaced in only the upper blade holder as in performing inside cutting operations. After desired tension is obtained, position tension lever (A) in the horizontal position, as shown in Fig. 7.

Adjusting the blade for proper tension is usually accomplished by trial and error. One method is to pull back on the blade tension lever (A) Fig. 8, the blade should start to have tension (resistance) when the blade tension lever is half way between open Fig. 8, and closed Fig. 7 positions. Finer blades require more tensioning while thicker blades require less tension.

Fig. 7

Fig. 8

ADJUSTING CLAMPING ACTION OF UPPER AND LOWER BLADE HOLDER CHUCK

Disconnect machine from power source.

Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper and lower blade holders. It should be noted, however, that very little adjustment is necessary and very little clamping force is required to hold the blade satisfactorily. As a rule of thumb, looking down at the table with the table insert slot in the 6 o’clock position, resistance on the blade locking lever should be felt when the upper blade locking lever reaches the 7 o’clock position, or when the lower blade locking lever reaches the 5 o’clock position.

1. Move the blade locking lever (A) Fig. 9, to the rear (open) position, as shown.

2. Turn chuck clamping knob (B) Fig. 9, clockwise to tighten and counterclockwise to loosen the clamping action of the blade holder chuck. Very little movement of knob (B) will be necessary. NOTE: Only the upper chuck is shown. Clamping action of the lower chuck is adjusted in the same manner and can be accessed by removing dust cup shown in Fig. 24.

Fig. 9

TILTING THE TABLE

Disconnect machine from power source.

The table on your scroll saw can be tilted 45° to the left for bevel cutting operations by removing the dust cup as shown in Fig. 24 and loosening table lock knob (A) Fig. 10, tilt the table to the desired angle indicated on degree scale (B) Fig. 11 and tighten lock handle (A) Fig. 10.

When bevel cutting, the holddown (B) Fig. 12, can be adjusted to lay flat on the stock by loosening screw (C) and tilting the holddown (B). Then tighten screw (C).

ADJUSTING THE TABLE

Disconnect machine from power source.

1. Loosen table lock knob as shown in Fig. 10 and move the table all the way to the right until angle indicator shown in Fig. 11 is on "0".

2. Using a square that includes a level, check to see if the table is level (A) Fig. 13, and is 90° to the saw blade (B), as shown.

3. If the table is not at 90° to the blade, adjust the table making certain screw (B) Fig. 14, contacts bottom of table surface when table is 90° to the blade. To make this adjustment loosen nut (C), turn screw (B) in or out the desired distance and tighten nut (C).

NOTE: After adjusting table, reposition the pointer (B) Fig. 11 to "0" degrees. Loosen the screw (A) Fig. 11 and adjust pointer (B) to "0" degree mark and retighten screw (A).

TABLE INSERT

Disconnect machine from power source.

The table insert (A) can be positioned in the saw table with the opening in the insert pointing to the front of the table, as shown in Fig. 18, or to the right as shown in Fig. 19.

With the table in the level position, 90° to the blade, the insert (A) should be positioned, as shown in Fig. 18. This allows for the blade to be pivoted forward after it is unclamped from the top blade holder, enabling you to quickly insert the blade into the next hole in a pattern when doing inside-cutting, as you will see later in this manual.

When tilting the table for bevel cutting operations the insert (A) should be positioned as shown in Fig. 19. This allows for clearance of the blade when tilting the table.

A blank table insert (B) Fig. 20, is supplied as standard equipment with your scroll saw and can be used when cutting very small workpieces to give added support to the bottom of the workpiece. Cut a slot into the blank and replace the standard insert (A) with the blank (B). The slot cut into the blank (B) will only be as wide as the blade giving maximum support to the bottom of the workpiece. Adhesive backed spacer pads (C) are also supplied for adjusting the table insert height relative to the table surface. Place three pads an equal distance apart on a cleaned surface to be applied to the blank insert. Pads can be stacked in order to achieve desired insert height.

MACHINE USE

FOLLOWING A LINE

With your scroll saw you should be able to perform straight or curved cuts with ease. Most beginners will experience blade wandering; however, they eventually learn to control it as they become more familiar with the machine. Use scrap material to practice cuts before starting a project. This enables you to develop your own style of cutting and you will discover what you can do with your saw.

Always hold the work firmly against the table and do not feed the workpiece too fast while cutting. Feed the workpiece only fast enough so that the blade will cut. Scroll saws cut faster across the grain than they do with the grain. Allow for this tendency when cutting patterns that shift rather quickly from with-the-grain cuts to cross-grain cuts.

Make "relief" cuts before cutting long curves and never attempt to cut a curve that is too tight for the blade being

used.

Fig. 21

INSIDE CUTTING

Inside cutting takes place when the blade is threaded through a hole in the workpiece. With your scroll saw, you can perform this operation quickly and easily as follows:

Loosen lock handle (A) Fig. 21, and raise the holddown (B). Release blade tension by moving the blade tension lever (C) to the horizontal position as previously explained. Release upper blade holder lever (D) as previously explained. This will release the blade (E) and allow you to thread the blade through the next hole in the pattern. Replace blade in upper blade holder and move blade tension lever to the vertical position to reapply blade tension. Lower holddown and you are ready to make the next cut.

TROUBLESHOOTING

For assistance with your machine, visit our website at www.deltamachinery.com for a list of service centers or call the DELTA Machinery help line at 1-800-223-7278 (In Canada call 1-800-463-3582).

CHOICE OF BLADE AND SPEED

Your scroll saw will accept a wide variety of 5" flat end blades and can be operated at any speed from 600 to 1650 cutting strokes per minute. Consider the following as a general guideline for selecting a blade and operating speed.

1. Use a finer blade for cutting thin workpieces, for hard materials, or when a smooth cut is required.

2. Use a coarser blade for cutting thick workpieces, when making straight cuts or for medium to soft materials.

3. Use a blade that will have 2 teeth in the workpiece at all times.

4. Most blade packaging is marked with the size of the wood the blade is intended to cut and the minimum radius which can be cut with that blade.

5. Slower speeds are generally more effective than faster speeds when using thin blades and making intricate cuts.

6. Always start at a slow speed and gradually increase the speed until the best cutting speed is obtained.

BLADE BREAKAGE

Blade breakage is usually caused by one or more of the following:

1. Bending the blade during installation.

2. Improper blade tension.

3. Improper blade selection for the work being cut.

4. Forcing the work into the blade too rapidly.

5. Cutting too sharp a turn for the blade being used.

6. Improper blade speed.

MAINTENANCE

KEEP MACHINE CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear certified safety equipment for eye, hearing and respiratory protection while using compressed air.

FAILURE TO START

Should your machine fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.

LUBRICATION & RUST PROTECTION

Apply household floor paste wax to the machine table, extension table or other work surface weekly. Or use a commercially available protective product designed for this purpose. Follow the manufacturer’s instructions for use and safety.

To clean cast iron tables of rust, you will need the following materials: a sheet of medium Scotch-Brite™ Blending Hand Pad, a can of WD-40® and a can of degreaser. Apply the WD-40 and polish the table surface with the Scotch-Brite pad. Degrease the table, then apply the protective product as described above.
