Shop Area: Woodshop

Tool: DeWalt 20" Scroll Saw

Requires in-person training: Yes 

Procedure Number

UG 110-09, Rev. 1




The scroll saw is used for cutting curves in thin material. It is capable of making tighter turns than the bandsaw and allows for interior cuts.

  • 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.
  • 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.
  • A gentle pluck of the blade should make a "musical" sound if tension is properly set.
  • If you are frequently breaking blades, decrease tension on the blade.

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.
  • Slower speeds are recommended for metals, plastics, harder woods and very thin materials.


  • Keep hands to side or rear of blade.
  • 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 to de-tension 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.


Overload Protector

  • 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.
                                            END OF THE PROCEDURE
