4.0 Glossary Some terms relevant to the scroll saw: Beam strength: A blade’s resistance to backward deflection caused by pressure of the workpiece. Perpendicular: 90° (right angle) intersection or position of vertical and horizontal planes, such as saw blade to table. 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 7-1. 1 4 4 3 5 1 1 Figure 7-2: hardware package JWSS22B-SHK Scroll saw (not shown) Leveling feet with hex nuts Rubber washers – (HP5) Lower blade holders (one installed) Blades, reverse skip tooth (one installed) Operator’s manual (not shown) Product registration card (not shown) 7.
7.5 Mounting to bench or stand 2. The leg extensions (#10, Figure 7-7) can be adjusted for height. 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. 3. If stand will not be bolted to the floor, install the leveling feet (shown in Figure 7-5) that were included with the scroll saw, onto the bottoms of the stand leg extensions (Figure 7-7). 4.
It is strongly recommended the foot pedal be secured in place using screws through the two holes. It may be secured directly to the floor or a wide board laid beneath the saw. Repair or replace immediately. damaged or worn cord This tool is for use on a nominal 120-V circuit, and has a grounded plug that looks like the plug illustrated in sketch A in Figure 8-1.
NOTE: If the blade holder set screw is backed out, turn it in with a 3mm hex wrench until it touches the tip of the knob when knob is tightened down. You may need to stabilize the blade holder with a 10mm wrench on the flats while doing this. 9.0 Adjustments Before making adjustments to saw, push rocker switch to OFF. Also unplug saw from power if working around blade area. 9.
9. • Try moving blade by hand to make sure it is secure. Pluck the blade with your finger, as you would a guitar string – it should emit a clear note if properly tensioned. Rotate arm adjustment knob (Figure 9-6) clockwise by hand. This will raise arm and apply more tension to blade. IMPORTANT: Rotating arm adjustment knob for tension purposes should only be done if absolutely needed, as it will affect later blade oscillation settings (sect. 9.7).
1. Turn off saw, unplug from power source. 2. Make sure blade is fully tensioned. 3. Set blade tilt to “0” (90 degrees). movement into the wood on the downstroke. For slower, fine detail work and more control, completely vertical blade movement is often preferred. 4. Place a machinists square or other 90-degree measuring device on table and against blade (Figure 9-2). Do not deflect blade by pushing into it.
5. 6. Turn motor shaft (N, Figure 9-5) with flat-blade screwdriver to observe blade motion. Alternatively, you may turn on saw to slowest speed to observe blade motion. into the blade, taking care not to bend or twist the blade. Slowly rotate entire motor by hand to adjust oscillation. Clockwise rotation will make blade movement more aggressive on downstroke. Counterclockwise will make blade more aggressive on upstroke. See Figure 9-5.
5. Hold workpiece firmly against table and feed workpiece directly into front edge of blade with steady pressure. See Figures 10-1 and 10-2. Do not use excessive pressure; allow the blade to do the work. Compensate for blade drift. Figure 10-3: fretwork cutting 11.0 User-maintenance Figure 10-1: straight cutting Always unplug scroll saw from power before performing maintenance. Failure to comply may result in serious personal injury. 11.
Bearings in the drive mechanism are pre-lubricated and sealed; no further attention is needed for these. 4. 11.3 Fuse inspection The scroll saw is equipped with a 5-amp fuse for overload protection. If the saw stops working, inspect fuse: 1. Unscrew fuse cap (Figure 11-2) and pull fuse out of cap. 2. If fuse has blown, replace it. 3. Install new fuse into cap, then screw cap into hole. Pull out brush and inspect.
12.0 Blade selection Refer to Figures 12-1 and 12-2. 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, density, etc.).
12.5 Tooth form Figure 12-2 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-18B Scroll Saw Table 3 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.
