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 possiblity 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 Machinery 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 com-
pletely assembled and installed according to the instruc­tions.
2. IF YOU ARE NOT thoroughly familiar with the oper-
ation 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 rec- ommended 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 irreg- ular 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 V-block 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.
28. NEVER perform layout, assembly or set-up work on the table while the saw is operating.
29. ALWAYS STOP the saw before removing scrap pieces from the table.
30. WHEN THE TOOL IS NOT IN USE, the switch should be locked in the “OFF” position to prevent unau­thorized use.
31. SHOULD any part of your Scroll Saw be missing, damaged or fail in any way, or any electrical component fail to perform properly, shut off switch and remove plug from power supply outlet. Replace missing, damaged or failed parts before resuming operation.
32. ADDITIONAL INFORMATION regarding the safe and proper operation of this product is available from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201, in the Accident Prevention Manual for Industrial Operations and also in the Safety Data Sheets provided by the NSC.

CONNECTING SCROLL SAW TO POWER SOURCE
POWER CONNECTIONS
A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be protected with a 20 Amp fuse. Have a certified electrician replace or repair a worn cord immediately. Before connect­ing the motor to a power line, make sure the switch is in the "OFF" position and be sure that the electric current is of the same characteristics as stamped on the motor name-plate. Running on low voltage will damage the motor.
WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCATIONS.
MOTOR SPECIFICATIONS
Your scroll saw is wired for 110-120 volt, 60 HZ current. Before connecting the saw to the power source, make sure the switch is in the "OFF" position.
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 a 3-pole receptacle which will accept the tools plug. When using an extension cord, be sure to use one heavy enough to carry the current of the scroll saw. An undersized cord will cause a drop in line voltage, resulting in loss and overheating. Fig. 14 shows the correct gage to use depending on the cord length. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
GROUNDING INSTRUCTIONS
WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.
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

ON-OFF AND VARIABLE SPEED SWITCHES
Fig. 18
The on-off switch (A) Fig. 18, and variable speed switch (B) is located on the left side of the scroll saw base, as shown. To turn the saw "ON," push the top portion of switch (A) and to turn the saw "OFF", push the bottom portion of the switch (A).
This scroll saw is supplied with variable speeds of 400 to 1800 strokes per minute. When the variable speed switch (B) Fig. 18, is rotated all the way to the left (coun­terclock-wise) the speed will be 400 strokes per minute. To increase the strokes per minute, rotate switch (B) to the right (clock-wise) until the desired speed is obtained. When the switch (B) is rotated all the way to the right (clockwise) the speed will be 1800 strokes per minute.
LOCKING ON-OFF SWITCH IN THE "OFF" POSITION
IMPORTANT: When the tool is not in use, the switch
should be locked in the off position using a padlock (C), as shown in Fig. 19. This padlock is available as an an accessory, Model 50-325 padlock.

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. 20, or to the right as shown in Fig.
21.
With the table in the level position, 90 degrees to the blade, the insert (A) should be positioned, as shown in Fig. 20. 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. 21. This allows for clearance of the blade when tilting the table.

6. Insert new blade into the lower and upper blade holders in the same manner, making certain the blade teeth are pointing down toward the table.
7. Apply blade tension by referring to the following section "ADJUSTING BLADE TENSION."
Fig. 28
Fig. 29
ADJUSTING BLADE TEN­SION
Tension is applied to the blade when the blade tension lever (A) Fig. 28, is in the rear position, as shown. When the lever (A) is moved forward, as shown in Fig. 29, blade tension is released.
To increase blade tension, turn knob (B) Fig. 29, clock­wise and to decrease blade tension, turn knob (B) counter-clockwise. When adjusting blade tension, lever (A) should be in the forward position, as shown in Fig.
29. 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. 29, 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.

INSIDE CUTTING
Inside cutting is where the blade must be threaded through a hole in the workpiece. The Delta 16" Scroll Saw has the capability of performing this operation quickly and easily as follows:
Fig. 37
Let's assume you are performing an inside cutting oper­ation on a project, similar to the one shown in Fig. 37, that has numerous inside cuts to be made. This can be accomplished quickly with the Delta saw. In Fig. 37, the operator has just completed one of the inside cuts and must move to the next hole.
Fig. 38
Fig. 39
Loosen lock handle (A) Fig. 38, and raise the spring 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.
Reassemble blade (E) Fig. 39, back into the upper blade holder and tighten blade by moving lever (D) forward. Move tension lever (C) to the rear as shown and lower spring holddown (B). You are ready to make the next inside cut.
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.

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.
To keep the scroll saw operating at peak efficiency, we recommend that a simple maintenance procedure be performed after approximately each 20 hours of use. Proceed as follows:

Your scroll saw will accept a wide variety of 5" flat end blades and can be operated at any speed from 400 to 1800 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.
