- Always wear approved safety glasses or face shield while operating the equipment.
- Before operating equipment, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair.
- Non-slip footwear or anti-skid floor strips are recommended.
- Closed toe shoes are required when working in a shop area.
- Do not wear gloves while operating the equipment.
- Make all machine adjustments or maintenance with the machine unplugged from the power source.
- Do not attempt to saw boards with loose knots or with nails or other foreign material, on its surface.
- KEEP GUARDS IN PLACE and in working order.
- DON’T FORCE TOOL.
- USE RIGHT TOOL.
- DON’T OVERREACH. Keep proper footing and balance at all times.
- Keep tools sharp and clean for best and safest performance.
- CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function–check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
- NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop.
- MATERIAL HOLD-DOWN must be properly set and remain in position during use.
- NEVER reach under the table when operating or make any adjustments when it is running.
- SECURE saw to work bench or stand with clamps or mounting hardware. Secure work bench or stand to floor.
- DO NOT use the upper arm as a lifting point.
- MAKE SURE blade tension is properly adjusted.
- DO NOT attempt to saw stock that does not have a flat surface, unless a suitable support is used.
- HOLD material firmly against table and feed into blade teeth at a moderate speed.
- TURN OFF motor if the material resists being backed out of an uncompleted cut. Use appropriate speed for applications.
- MAKE “relief” cuts before cutting long curves.
Blade Tension Lever
- Move the blade tension lever to the left to increase tension on the blade.
- The proper degree of tension varies with different blade sizes.
- If you are frequently breaking blades, decrease tension on the blade.
- The material hold-down should contact the surface of the workpiece.
- To adjust the material hold-down, loosen the thumbscrew and move the rod up or down.
- The material hold-down must be beveled when the table is beveled.
- To bevel the material hold-down, loosen the allen screw and bevel the material hold-down until it is parallel to the table.
- Retighten the material hold-down before cutting.
- When cutting, ensure the material hold-down does not contact the bottom arm of the scroll saw. Your scroll saw has a maximum thickness capacity of 2".
- Do not cut material thicker than 2".
Speed Control Knob
- Variable speed control, from 400 to 1,750 strokes per minute.
- To operate the variable speed feature, turn the speed control knob with the saw running.
- To increase the speed, turn the knob clockwise.
- The numbers on the speed control knob represent speed ranges.
- One is the minimum speed, 8 is the maximum speed.
- Slower speeds are recommended for metals, plastics, harder woods and very thin materials.
- Hold material firmly against table.
- Always feed material toward the blade.
- Feed the workpiece fast enough to allow the blade to cut, but do not force material into the blade too quickly.
- The table bevels 45° left and right.
- A detent is set at 0°.
- To bevel the scroll saw table, loosen the bevel lock knob, and bevel the table to the desired setting, indicated by the bevel pointer.
- Before tilting the table for bevel cuts of 45°, check the clearance around the lower thumbscrew.
- To facilitate an accurate 45°cut the thumbscrew and setscrew may need to change places.
- On the setscrew side, sufficient clearance is available.
Fretwork - INSIDE CUTS
1. Drill a pilot hole in your workpiece.
2. Make sure the blade tension lever is moved fully to the right
3. Loosen the top thumbscrew blade clamp.
4. Leaving the blade held in place by the bottom blade clamp, lift the top arm of the scroll saw. Thread the saw blade through the pilot hole in your workpiece and reattach the blade by tightening the top thumbscrew.
5.Readjust the blade tension and begin the inside cut.
6. Alternately, you can loosen the bottom thumbscrew blade clamp in step 3 above, and thread the blade through the top of the workpiece.
- Scroll saw is equipped with a 3 amp overload protection fuse.
- If saw becomes overloaded and stops operating, turn off the scroll saw, check for a blown fuse by removing the fuse cap.
- Replace with fuse #3AG Fast Acting, 1 1/4" long x 1/4" diameter.
