MANUAL INSTRUCTION
GENERAL 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 Machinery strongly recommends that this machine not be modified and/or used for any application other than that for which it was designed.

ADDITIONAL SAFETY RULES FOR
SCROLL SAWS
WARNING: Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
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 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. Please also refer to the American National Standards Institute ANSI 01.1 Safety Requirements for Woodworking Machinery and the U.S. Department of Labor OSHA 1910.213 Regulations.
SAVE THESE INSTRUCTIONS. Refer to them often
and use them to instruct others.

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 motor to the power line, make sure the switch 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 motor.
WARNING: SHOCK HAZARD. DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
GROUNDING INSTRUCTIONS
WARNING: SHOCK HAZARD. THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE
OPERATOR FROM ELECTRIC SHOCK. Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the “OFF” position.
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 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 equipmentgrounding 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.
WARNING: SHOCK HAZARD. IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLYGROUNDED. IF YOU ARE NOT SURE HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

(B) is located on the right side of the scroll saw base, as |
|
|
shown. To turn the saw "ON," push the switch (A) up to |
|
|
the “ON” position. To turn the saw "OFF", push the |
|
|
switch (A) down to the “OFF” position. |
B |
A |
|
|
The scroll saw is equipped with a variable speed control knob (B) Fig. 17. The variable speed range is 400 to 1800 strokes per minute. When the variable speed knob
is rotated all the way to the left (counterclockwise) the Fig. 17 speed will be 400 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 1800 strokes per minute.
LOCKING ON-OFF SWITCH
IN THE "OFF" POSITION
IMPORTANT: When the machine is not in use, the switch should be locked in the OFF position using a padlock (C) Fig. 18, with a 3/16" diameter shackle to prevent unauthorized use.

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. 19, or to the right as shown in Fig. 20.
With the table in the level position, 90 degrees to the blade, the insert should be positioned, as shown in Fig. 19. This allows for the blade to be pivoted forward after it is unclasped from the top blade holder, enabling you to quickly insert the blade into the next hole in a pattern when doing inside-cutting.
When tilting the table for bevel cutting operations the insert (A) should be positioned as shown in Fig. 20. This allows for clearance of the blade when the table is tilting.
A table insert blank (B) Fig. 21, 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.

ADJUSTING BLADE
TENSION
Tension is applied to the blade when the blade tension lever (A) Fig. 27, is in the rear position, as shown. When the lever (A) is moved forward, as shown in Fig. 28, blade tension is released.
When adjusting blade tension, lever (A) should be in the forward position, as shown in Fig. 28. To increase blade tension, turn knob (B) Fig. 28, clockwise and to decrease blade tension, turn knob (B) counterclockwise. 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. One method is to pull back on the blade tension lever (A) Fig. 28, the blade should start to have tension (resistance) when the blade tension lever is half way between open Fig. 28, and closed Fig. 27. Finer blades require more tensioning while thicker blades require less tension.
ADJUSTING CLAMPING ACTION OF UPPER BLADE HOLDER
Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper blade holder. It should be noted, however, that very little adjustment is necessary and very little clamping force is required to hold the blade.
1.Move the chuck locking lever (C) Fig. 23, to the rear (open) position, as shown.
2.Turn locknut (C) Fig. 29, clockwise to tighten and counterclockwise to loosen the clamping action of the, blade holder. Very little movement of locknut (C) is necessary.

TILTING THE TABLE
The table on your scroll saw can be tilted 45 degrees to the left for bevel cutting operations by loosening table lock handle (A) Fig. 30, tilt the table to the desired angle and tighten lock handle (A).
When bevel cutting, the holddown (B) Fig. 31, can be adjusted to lay flat on the stock by loosening screw (C) and tilting the holddown (B) accordingly. Then tighten screw (C).
ADJUSTING THE TABLE
1.Loosen the table locking handle, and move the table all the way to the right.
2.Using a square (A) Fig. 32, check to see if the table is 90 degrees to the saw blade, as shown.
3. If the table is not at 90 degrees to the blade, adjust the table accordingly making certain screw (B) Fig. 33, contacts bottom of table surface when table is 90 degrees to the blade. Screw (B) can be adjusted by loosening nut (C), thread screw (B) in or out the desired distance and tighten nut (C).

FOLLOWING A LINE
WARNING: CUT HAZARD: Keep hands away from blade. 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.
INSIDE CUTTING
Inside cutting is where the blade must be threaded through a hole in the workpiece. The Shopmaster 16" Scroll Saw has the capability of performing this operation quickly and easily as follows:
Inside cutting can be accomplished quickly with the saw. In Fig. 36, the operator has just completed one of the inside cuts and must move to the next hole.
Fig. 36
Loosen lock handle (A) Fig. 37, 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.
Place blade (E) Fig. 38, 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.

LUBRICATION
It is recommended that the scroll saw be oiled after each 20 hours of use, as follows:
1.WARNING: DISCONNECT MACHINE FROM POWER SOURCE.
2.Remove four screws (A) Fig. 39, and remove side panel (B) from the scroll saw.
3.Release blade tension by pulling tension lever (C) Fig. 40, forward as shown.
4.Lubricate the shafts of two special screws (D) Fig. 41, with a few drops of light machine oil in the areas where they pass through the connecting link (E). NOTE: DO NOT REMOVE SPECIAL SCREWS TO LUBRICATE.
5.Remove two pivot bolts (F) Fig. 42.
6.Thoroughly clean grease from shafts (G) Fig. 42, of both pivot bolts (F) and lubricate shafts (G) with a few drops of light machine oil.
7.Reassemble two pivot bolts (F) Fig. 42, to machine.
8.Replace side panel removed in STEP 2 and reapply tension to the blade.

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 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.
TROUBLESHOOTING - 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.
