25. Maintain tools with care. Keep saw blades sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories. 35. Always keep fingers and hands away from blade. Avoid awkward hand positions where a sudden slip might cause hand to move into or toward the blade. 26. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do not use your hands. 36. Always hold stock firmly against table.
1.2 Switch lock-out To safeguard your machine from unauthorized operation and accidental starting by young children, the use of a padlock (not included) is highly recommended. See Figure 1.

4.0 Glossary Some terms relevant to the scroll saw: Perpendicular: 90° (right angle) intersection or position of vertical and horizontal planes, such as saw blade to table. Beam strength: A blade’s resistance to backward deflection caused by pressure of the workpiece. Bevel edge cut: Tilt of blade between 0° and 45° to perform angled cutting operation. Pin-end blade: Blade that requires a pin to secure it to the saw. (These are not suitable for intricate fretwork.

7.0 Setup and assembly Read and understand all assembly instructions before attempting assembly. Saw must remain unplugged from power source during assembly procedures. 7.1 Shipping contents Refer to Figure 4. 1 4 2 1 1 1 5 4 1 1 Figure 5: hardware package JWSS22B-SHP Scroll saw (not shown) Leveling feet with hex nuts Lower blade holders Foot pedal assembly Dust port Blade rack Blades, skip type (not shown) Rubber washer – (HP5) Operator’s manual (not shown) Warranty card (not shown) 7.
7.5 Mounting to bench or stand included with the scroll saw, onto the bottoms of the stand leg extensions. The scroll saw should be installed upon a sturdy, flat surface with all four legs contacting the surface. Do NOT install with saw partially hanging over edge of table or workbench. If scroll saw will not be bolted down to a surface, install the four foot pads to reduce vibration. See Figure 8. Lower hex nut may be adjusted for height. Tighten top hex nut down against saw foot. 4.
7.9 Dust collection properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet (sketch A) can be installed by a qualified electrician. The green colored rigid ear, lug, or the like extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by a metal screw. Slide dust port into the slot on underside of table.
9.0 Adjustments Before making adjustments to saw, push rocker switch to OFF. Also unplug saw from power if working around blade area. 9.1 Arm tilt The table remains stationary, so the operator’s hands can remain in the same comfortable position, with no risk of the workpiece sliding off the table. The arm can be tilted up to 45-degrees left or right for beveled cuts, which are frequently used in projects such as marquetry. Figure 14: installing blade into holder Refer to Figure 13. 1.
TIP: If changing a blade while cutting fretwork, you may first push blade through pilot hole in workpiece, then install blade to saw. See Figure 16. This prevents having to raise the arm for the first cut. Figure 18: arm adjustment knob 9.4 Material hold-down Refer to Figure 19. Adjust material hold-down as close to workpiece as possible without impeding workpiece movement. Figure 16: installing blade with workpiece For vertical adjustment, Loosen knob (H, Figure 19) and slide hold-down to position.
4. Place a machinists square or other 90-degree measuring device on table and against blade (Figure 20). Do not deflect blade by pushing into it. This adjustment is based upon user’s preference; as the scroller gains experience, he/she will get a feel for the oscillation that is most efficient for the work at hand. 1. Turn off saw and unplug. 2. First verify that upper arm is parallel to table surface (Figure 22).
6. Slowly rotate entire motor by hand to adjust oscillation. Clockwise rotation will make blade movement more aggressive on downstroke. Counter-clockwise will make blade more aggressive on upstroke. See Figure 23. TIP: If more rotation is needed, turn off saw and install motor mount screws in second set of holes behind motor flange. 7. 7. Make relief cuts as needed to prevent binding of blade in workpiece. 8. A blade has a tendency to follow the wood grain.
11.0 User-maintenance Always unplug scroll saw from power before performing maintenance. Failure to comply may result in serious personal injury. 11.1 General maintenance Clean wood dust from the saw frequently, using a vacuum or compressed air, or damp cloth. Use a soft bristle brush for crevices. Figure 25: straight cutting Use proper eye and respiratory protection if using compressed air. Keep the table clean.
4. Pull out brush and inspect. Brush should be replaced if any of the following are discovered: • Brush has worn to about 1/2-inch long. • • Signs of crumbling, burning or breaking. End of brush is rough or pitted. • Abnormal coloration of spring • Broken lead in spring 5. • Collapsed spring Install new brush (or reinstall current brush) and gently press it all the way into hole until the brass clip is secured. 11.4 Commutator brush inspection 6. Install cap.
12.0 Blade selection Refer to Figures 31 and 32. The following information is general in nature. The scroller is encouraged to research specific options to meet project needs. Note that the same specifications may vary among manufacturers. A wide array of blades are available for the scroll saw. Woodworking blade sizes range from #3/0 to #12. Here are factors to consider when selecting a blade: • Type of material to be cut (hardwood, softwood?).
12.5 Tooth form Figure 32 shows common blade forms. Tooth form has an effect on cutting rate. Regular: Standard blade form with evenly spaced teeth and zero-degree rake angle. Offers clean cuts at slower feed rates. Skip Tooth: More space between teeth, for good chip removal and fast cuts. Double Tooth: A skip tooth with larger gaps between tooth sets; good chip removal, fast cutting. Reverse Tooth: Prevents underside tear-out, leaves clean edge.
14.0 Troubleshooting JWSS-22B Scroll Saw Symptom Possible Cause Correction * Motor will not start. Low voltage. Check power line for proper voltage. Open circuit in motor or loose connection. Damaged cord or plug. Inspect all lead connections on motor for loose or open connections. Inspect and replace. Carbon brushes worn. Replace brushes. Short circuit in line cord or plug. Inspect cord or plug for damaged insulation and shorted wires.
