ADJUSTMENTS

INSTALLING BLADES

Scroll saw blades wear out quickly and must be replaced
frequently for best cutting results. Expect to break some
blades while you learn to use and adjust your saw. Blades
generally stay sharp for 1/2 hour to 2 hours of cutting,
depending on the type of material and speed of operation.

Pin End Blades
