SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop. If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your personal safety is your responsibility.
This machine was designed for certain applications only. Delta strongly recommends that this machine not be modified and/or used for any application other than that for which it was designed. If you have any questions relative to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should be performed on the product.

ADDITIONAL SAFETY RULES
FOR SCROLL SAWS
1. DO NOT operate your scroll saw until it is completely assembled and installed according to the instructions.
2. IF YOU ARE NOT thoroughly familiar with the operation of Scroll Saws, obtain advice from your supervisor, instructor or other qualified person.
3. YOUR SCROLL SAW MUST be securely fastened to a stand or workbench. If there is any tendency for the stand or workbench to move during operation, the stand or workbench MUST be fastened to the floor.
4. THIS SCROLL SAW is intended for indoor use only.
5. MAKE SURE blade is properly tensioned before operating saw.
6. TO AVOID blade breakage ALWAYS adjust blade tension correctly.
7. MAKE SURE the blade teeth point downward toward the table.
8. NEVER turn the saw “ON” before clearing the table of all objects (tools, scraps of wood, etc.).
9. DO NOT cut material that is too small to be safely supported.
10. AVOID awkward hand positions where a sudden slip could cause a hand to move into the blade.
11. ALWAYS keep hands and fingers away from blade.
12. ALWAYS adjust holddown foot for each new operation.
13. DO NOT USE dull or bent blades.
14. DO NOT attempt to saw material that does not have a flat surface, unless a suitable support is used.
15. MAKE “relief” cuts before cutting long curves.
16. NEVER attempt to cut a curve that is too tight for the blade being used.
17. WHEN backing a blade out of a workpiece, the blade may bind in the saw kerf. This is usually caused by sawdust in the kerf. If this happens, turn “OFF” the switch and remove plug from power source outlet. Wedge open the kerf and back blade out of the workpiece.
18. THE USE of attachments and accessories not recommended by Delta may result in the risk of injuries.
19. ALWAYS hold the work firmly against the table.
20. DO NOT feed the material too fast while cutting. Only feed the material fast enough so that the blade will cut.
21. NEVER start the Scroll Saw with the stock pressed against the blade.
22. WHEN cutting a large workpiece MAKE SURE the material is supported at table height.
23. USE CAUTION when cutting material which is irregular in cross section which could pinch the blade before the cut is completed. A piece of moulding for example must lay flat on the table and not be permitted to rock while being cut.
24. USE CAUTION when cutting round material such as dowel rods or tubing. They have a tendency to roll while being cut causing the blade to “bite.” Use a V­block to control the piece.
25. ALWAYS release blade tension before removing the blade from the upper or lower blade holders.
26. MAKE CERTAIN table tilting lock is tightened before starting the machine.
27. NEVER reach under the table while the machine is running.

MINIMUM GAUGE EXTENSION CORD
EXTENSION CORDS
Use proper extension cord. Make sure your extension cord is in good condition. When using an 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. Fig. 1 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.
Fig. 1
GROUNDING INSTRUCTIONS
WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.
1. All grounded, cord-connected tools:
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 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 conductor 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 tool is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and 3-pole receptacles that accept the tool’s plug.
Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. 2. The tool has a grounding plug that looks like the plug illustrated in Fig. 2. A temporary adapter, which looks like the adapter illustrated in Fig. 3, may be used to connect this plug to a 2-pole receptacle as shown in Fig. 3 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: IN ALL CASES, MAKE SURE THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. NEVER REMOVE GROUNDING PRONG FROM POWER PLUG.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

FASTENING SCROLL SAW TO SUPPORTING SURFACE
Your scroll saw MUST be securely fastened to a stand or workbench using the three holes in the base, two of which are shown at (A) Fig. 4.
IMPORTANT: If there is any tendency for the stand or workbench to move during operation, the stand or workbench MUST be fastened to the floor.
ON-OFF SWITCH AND VARIABLE SPEED CONTROL
The on-off switch (A) Fig. 5, and variable speed control (B) are located on the right front side of the scroll saw base, as shown. To turn the saw “ON”, push the switch (A) up and to turn the saw “OFF”, push the switch (A) down.
This scroll saw is supplied with variable speed control ranging from 600 to 1650 strokes per minute. Turn variable speed control (B) Fig. 5, counterclockwise to reduce speed and clockwise to increase speed.
LOCKING SWITCH IN THE “OFF” POSITION
IMPORTANT: When the tool is not in use, the switch should be locked in the “OFF” position. Grasp the
switch toggle (B) Fig. 6, and pull it out as shown. With the switch toggle (B) removed, the switch, (A) Fig. 6, will not operate.

TABLE INSERT
The table insert (A) can be assembled to the saw table with the opening in the insert pointing to the front of the table, as shown in Fig. 7, or to the right as shown in Fig. 8.
With the table in the level position, 90° to the blade, the insert (A) should be positioned, as shown in Fig. 7. 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. 8. This allows for clearance of the blade when tilting the table.
A table insert blank (B) Fig. 9, 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.
CHANGING BLADES
1. WARNING: TO AVOID INJURY FROM ACCIDENTAL STARTING ALWAYS TURN SWITCH “OFF” AND REMOVE SWITCH INSERT AND DISCONNECT THE POWER CORD BEFORE REMOVING OR REPLACING BLADE.
2. Remove table insert (A) Fig. 10, and release blade tension by pulling tension lever (B) forward, as shown.

ADJUSTING BLADE TENSION
Tension is applied to the blade when the blade tension lever (A) Fig. 15, is in the rear position, as shown. When the lever (A) is moved forward, as shown in Fig. 16, blade tension is released.
To increase blade tension, turn lever knob (B) Fig. 16, clockwise and to decrease blade tension, turn knob (B) counterclockwise. When adjusting blade tension, lever (A) should be in the forward position, as shown in Fig.
16. NOTE: It is necessary to adjust the blade tension knob (B) only when the blade is removed from both upper and lower blade holders and a new or different type of blade is assembled to the holders. 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.
Adjusting the blade for proper tension is usually accomplished by trial and error; however, a good method to use is to pluck the rear of the blade, like a guitar string, after the tension lever (A) Fig. 15, is moved to the rear. A high-pitched tone of the blade should be heard and this usually indicates proper tension. Finer blades require more tensioning (a higher pitched sound) while thicker blades require less tension.
ADJUSTING CLAMPING ACTION OF UPPER AND LOWER BLADE HOLDER CHUCK
Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper and lower blade holder chuck. 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 holder chuck locking lever (A) Fig. 17, to the rear (open) position, as shown.
2. Turn chuck clamping knob (B) Fig. 17, 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. 12.

TILTING THE TABLE
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. 12 and loosening table lock knob (A) Fig. 18, tilt the table to the desired angle indicated on degree scale (B) Fig. 19 and tighten lock handle (A) Fig.
18.
When bevel cutting, the holddown (B) Fig. 20, can be adjusted to lay flat on the stock by loosening screw (C) and tilting the holddown (B) accordingly. Then tighten screw (C).
LEVELING THE TABLE
1. Loosen table lock knob as shown in Fig. 18 and move the table all the way to the right until angle indicator shown in Fig. 19 is on “0”.
2. Using a square that includes a level, check to see if the table is level (A) Fig. 21, and is 90° to the saw blade (B), as shown.
3. If the table is not at 90° to the blade, adjust the table accordingly making certain screw (B) Fig. 22, contacts bottom of table surface when table is 90° to the blade. Screw (B) can be adjusted by loosening nut (C), turn screw (B) in or out the desired distance and tighten nut (C).
Note: After adjusting table, reposition the angle indicator (B) Fig. 19 to "O" degrees.

The holddown (A) Fig. 23, may be adjusted front to rear, by loosening set screw (B) Fig. 24, and positioning the holddown in the desired location. Once the holddown is in the desired location, tighten set screw (B), Fig. 24.
ADJUSTING DUST BLOWER
The dust blower (A) Fig. 24, may be positioned to direct air to the most effective point on the cutting line.
DUST COLLECTION CUP
A dust collection cup (A) Fig. 25 is provided and can be attached to a shop vacuum system by utilizing the port covered by cap (B).
INSIDE CUTTING
A blade threaded through a hole in the workpiece is inside cutting. The Delta 16" Scroll Saw has the capability of performing this operation quickly and easily.
Loosen lock knob (A) Fig. 26, and raise the holddown (B). Release blade tension by moving tension lever (C) forward and loosen upper blade holder by moving lever (D) to the rear as shown. This will release the blade (E). Insert the blade (E) into the next hole in the pattern, as shown.

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 smoother 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 optimum cutting speed is obtained.
LUBRICATION
To keep the scroll saw operating at peak efficiency, we recommend that a simple maintenance procedure be performed after each 20 hours of use (approximately) as follows:
1. MAKE CERTAIN THE MACHINE IS DISCON-
NECTED FROM THE POWER SOURCE.
2. Tilt the table 45° to the left as shown in Fig. 28.
3. Remove four rubber grommets (A) Fig. 29 that cover the lubrication access holes.
4. Lubricate the pivot points in each of the four access holes with a few drops of light machine oil as shown in Fig. 30.
5. Reassemble the four grommets as shown in Fig. 29, to machine.
6. Apply lightweight grease or anti-sieze to lubricate the tensioning lever (A) Fig. 15 where it pivots on the upper chuck .

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.
13
FOLLOWING A LINE
With your scroll saw you should be able to cut a straight or curved line 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 way of cutting and you will find out what you can and cannot 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.
ACCESSORIES

Two Year Limited Warranty
Delta will repair or replace, at its expense and at its option, any Delta machine, machine part, or machine accessory which in normal use has proven to be defective in workmanship or material, provided that the customer returns the product prepaid to a Delta factory service center or authorized service station with proof of purchase of the product within two years and provides Delta with reasonable opportunity to verify the alleged defect by inspection. Delta may require that electric motors be returned prepaid to a motor manufacturer’s authorized station for inspection and repair or replacement. Delta will not be responsible for any asserted defect which has resulted from normal wear, misuse, abuse or repair or alteration made or specifically authorized by anyone other than an authorized Delta Service facility or representative. Under no circumstances will Delta be liable for incidental or consequential damages resulting from defective products. This warranty is Delta’s sole warranty and sets forth the customer’s exclusive remedy, with respect to defective products; all other warranties, express or implied, whether of merchantability, fitness for purpose, or otherwise, are expressly disclaimed by Delta.
