SPECIAL WARNINGS WHEN USING THIS SCROLL SAW
Brought to You by Augusta Flint
Using this powerful tool may create special hazar ds.
Operating the Saw.
1. Avoid overloading the saw . If the speed drops abnormally , decrease the pressure immediately .
2. Always use sharp blades which are suited to the material you are cutting. If the blade stops abruptly,
or becomes blocked, turn off the power switch immediately .
3. Do not apply excessive pressure to the work piece while cutting.
4. Be careful to use the power switch properly . Be aware that the saw will continue to
operate while the power switch is ON. Y ou must manually turn the switch to OFF to stop the motor .
5. Never start the saw while the blade is in contact with any material. Allow the saw to reach its
normal operating speed before applying the workpiece to the blade.
6. Never operate the saw if the metal safety guard (drop foot) is not in place.
7. Never touch the blade, upper blade holder or any other moving parts while the saw is in operation.
8. Never walk away from the saw until it has stopped operating completely.
9. Before cutting, adjust the drop foot to ride on the surface of the workpiece. This will prevent the
workpiece from “jumping” up and down, which can damage the workpiece, the saw , and the blade.
10. Hold the workpiece firmly while cutting. The action of the blade against the workpiece can cause it
to “kick out”. If you experience excessive “kick out” check your blade to assure that it is the proper
type for the material being cut, that it is installed with the teeth down, and that it is sharp.
11. Always wear ANSI certified eye protection, and do not allow others nearby when using this tool.
Cuttings and splinters can be ejected at high speed while cutting.
12. Do not handle the blade immediately after use; it may be very hot, potentially causing burns
or injury .
13. Make sure the workpiece is free of nails or other debris which can interfere with the cutting process,
and possibly cause damage or injury .
14. Y our saw must be bolted or clamped to the workbench prior to use.
Ensure the safety of the workplace.
1. Always wear ANSI-approved eye protection when trimming.
2. Clear the work area of any parts or debris that could cause injury by interfering with the
cutting process.
3. Remove trimmed off sections immediately to prevent their being ejected by the saw .
4. Keep children and unauthorized persons away from the area when cutting.
5. Avoid distractions while cutting.
6. Never leave the saw unattended where children or unauthorized persons can use it without
supervision.
Inspect the Scroll Saw before use.
1. Before cutting, run the tool for about 10 seconds to ensure that all moving parts are running
smoothly and there are no loose parts, rattles, or sparking that would indicate damage.
2. Repair any damage before using this tool.
3. Be sure the blade is firmly and properly installed before use. Improperly installed blades may eject
suddenly at high speed from the saw .

BASIC OPERA TION
This saw uses a very thin, very fine blade, which moves up and
down at high speed. This type of saw is ideal for making
detailed curved cuts in relatively thin materials. Fretwork, signs,
and gingerbread decorations can be readily made with a scroll saw.
Figure 1. Electrical Contr ols
and Fuse Cover.
1. After selecting and installing the proper blade for the work at hand, position the workpiece on the
table.
2. Lower the foot onto the workpiece, so that it just rests on the surface of the material. Tighten the
foot into position with the knob.
3. With the material not touching the blade, turn the power ON by pressing the upper part of the
rocker switch.
4. When the saw has come up to full speed, gently push the edge of the workpiece into the blade.
Notice how well the blade makes the cut. Adjust the speed if necessary .
NOTE: In general, harder and thinner materials r equire finer saw teeth and higher speeds. Softer and
thicker materials generally requir e slower speeds. Finding the ideal saw blade and speed combination may require some experimentation and experience.
5. As you work, remove cut off pieces of work material.
6. For cutting enclosed areas, first drill a hole through the cut-out area, install the blade through the
hole, then cut out the enclosed area with the scroll saw .
7. Keep your hands away from the saw blade while using this saw. Where possible, use a push stick to
guide the workpiece into the blade, keeping your hands away .

Figure 2. Basic Components
Brought to You by Augusta Flint
and Features of Your Scroll Saw .
1. T able. Provides a working surface to support the workpiece.
2. Sawdust Blower . Keeps your workpiece clean for more accurate scroll cuts. For best results, adjust the
blower to the point at which the blade is cutting. T o adjust, loosen the set screw in the drop foot, position the
blower and retighten the screw . CAUTION: do not overtighten the screw , which may collapse the tube.
3. Power Cord. This is a 3-wire UL approved cord and CSA-approved grounded plug for use in a 110-120 V olt,
60Hz outlet only . Be sure your power supply is protected with an appropriate breaker switch.
4. Drop Foot. The foot should always be adjusted so it just rests on top of the workpiece.. You want to prevent the
workpiece from lifting, but not create drag on the surface.
5. Drop Foot Lock Knob. Loosen and tighten this knob as you adjust the drop foot.
6. Blade T ension Knob. Allows you to loosen or tighten the blade tension. Y ou also use this knob when replacing
the blade.
7. T able Lock Knob. This knob allows you to adjust the table angle up to 45 degrees.
8. Degree Scale. This scale indicates the degree from horizontal that you have the table set.
9. Power Switch. Turn the switch up to turn ON, and down to turn OFF .
10. ElectricalBreaker Switch. This fuse will automatically cut off power to the saw in the event of a short or
surge in the power supply. If the fuse activates, find and repair the source of the problem before replacing the fuse.
11. Speed Control. Turn this knob to the right to increase saw blade speed, and to the left to reduce speed.
12. T able Insert. This should always be in place and flush with the table during the cutting operation.

INSTALLING THE SA W BLADE
Brought to You by Augusta Flint
Fig. 3. Installing the Blade
Your new scroll saw accepts 5” pin-type blades. Your saw is also equipped with blade
adapters that allow you to use a variety of 5” plain-end blades.
WARNING: To prevent personal injury, always disconnect the plug from the power source
before changing blades or making adjustments.
1. Rotate the blade tension knob counter-clockwise to release blade tension.
2. Remove the table insert and remove the blade from the upper and lower blade holders by pulling
forward on the blade and then lifting the blade through the access hole in the table. Slight downward
pressure against the upper holder may be helpful when removing the blade from upper holder.
3. Look at the blade holders closely and notice the blade slots and recesses in the blade holders. The
blade holders are made so you can position the blade for cutting from the front or from the side of
the saw as shown in Figure 3 above. Cutting from the side of the saw will be necessary if your
workpiece exceeds 16 inches in length. This allows your scroll saw to cut like a band saw . This
option is for 0O table setting only .
4. In order to cut, and to avoid uncontrollable lifting of the workpiece, the teeth of the blade used on
the scroll saw should always point downward.
5. Install the blade by inserting one end of the blade through the access hole in the table and hook the
blade pin in the pin recess in the lower blade holder. Slide the top blade pin into the pin recess of the
inner upper blade holder. Y ou may need to press down lightly on the upper blade holder to install
the blade.
6. Carefully tighten the blade by rotating the blade tension knob clockwise until you feel the slack in the
blade removed. Double check to see that pins are properly located in the blade holder . Then turn
the blade tension knob ONE full turn clockwise. This amount of blade tension should do well for
most cutting operations and blades.

ADJUSTING AND USING THE TABLE ALIGNMENT FEATURE
Brought to You by Augusta Flint
Fig. 4. Aligning the Table
and adjusting the Scale
Aligning the Degree Scale Pointer
1. Loosen the table lock knob and move the table until it is
approximately perpendicular, that is, at a right angle to
the blade.
2. Place a small square on the table next to the blade as
shown in Figure 4 to check if the table is 90
O
to the
blade. If adjustment is needed, raise or lower the table
until it is as close to 90O as possible. Securely tighten the
table lock knob.
3. Loosen the screw holding the degree scale pointer, as
shown in Figure 4. Move the pointer to the 0O degree
marker on the scale, and securely tighten the screw .
Remember the scale is a convenient guide, but should not
be relied upon for extremely accurate cutting. Make
practice cuts in scrap wood to determine if your angle
settings are correct.
Setting the Table for Horizontal or Bevel Cutting.
1. Loosen the table lock knob, and the saw table can be
tilted to the left and locked in any angle from 0O degree
horizontal cutting position up to 45O for bevel cutting.
2. A degree scale is also provided under the work table as a
convenient reference for setting the approximate table
angle for bevel cutting. When greater precision is
required, make practice cuts and adjust the table as
necessary for your requirements.
3. NOTE: When cutting at angles, the drop foot can be tilted
so it is parallel with the table surface, and rests flush
against the workpiece. T o tilt drop foot, loosen the allen
screw , tilt the foot so it is parallel with the table, and then
securely retighten the screw .
