An electric scroll saw or fretsaw lets you cut curves, fretwork patterns and inlays in timber and plywood. Cutting is easy, yet many beginners give up after the first snapped blade, when the real cause is usually set up and the condition of the machine.
Like any woodworking machine, it is constantly covered in dust inside and out. Dust clogs the arm pivots, blade clamps and switch, and in an unheated shed or garage moisture adds to the problem. A monthly service takes little time and keeps the saw in shape.
What you will need
Important: Switch off and unplug the saw before cleaning, changing a blade or lubricating. Keep your fingers away from the blade even when the machine is off.
Step 1
Choose the right blade
Blades come in different widths: fine ones are for tight turns and detailed patterns, wider ones for long straight cuts. The wrong blade, too little tension or feeding too fast is what usually breaks them. Tension the blade until it rings when plucked lightly and never force the work into the teeth.
Step 2
Remove the dust
After work, wipe dust off the blade, table and body with a soft cloth and brush. Vacuum sawdust from under the table and around the motor housing, especially near the cooling vents.
Step 3
Clean off deposits
If resin or old grease mixed with dust remains on metal parts, spray a little WD-40 Multi-Use onto a corner of the cloth and wipe gently. It dissolves the deposits and displaces moisture, protecting the metal from rust.
Step 4
Lubricate the moving parts
The blade assembly and arm bearings are in constant motion. Use the precision straw of WD-40 Smart Straw to treat the arm pivots, blade clamps and tension screw, then turn the mechanism by hand a few times. Service the motor bearings according to the manufacturer's manual.
Always wipe off the excess so it does not collect dust.
Tip: Before applying a finish such as lacquer or wax, make sure no silicone from the table has transferred to the piece: wipe it with a clean dry cloth or give it a light sanding with fine paper.
What next
Service the saw monthly and remove dust after every session, and it will cut cleanly and accurately for years. For other workshop machines, see our band saw and wood lathe guides.
These uses come from the experience of WD-40 users in many countries. Always follow the instructions and warnings on the product label.
