BLADE BREAKAGE
Blade breakage is usually caused by one or more of the following:
1. Bending the blade during installation.
2. Improper blade tension.
3. Improper blade selection for the work
being cut.
4. Forcing the work into the blade too rapidly.
5. Cutting too sharp a turn for the blade
being used.
6. Improper blade speed.
CHOICE OF BLADE AND SPEED
Your scroll saw will accept a wide variety of 5" flat end blades and can be operated at any speed
from 300 to 2000 cutting strokes per minute. Consider the following as a general guideline for
selecting a blade and operating speed.
1. Use a finer blade for cutting thin workpieces, for hard materials, or when a smoother cut is
required.
2. Use a coarser blade for cutting thick workpieces, when making straight cuts or for medium
to soft materials.
3. Use a blade that will have 2 teeth in the workpiece at all times.
4. Most blade packaging is marked with the size of the wood the blade is intended to cut and
the minimum radius which can be cut with that blade.
5. Slower speeds are generally more effective than faster speeds when using thin blades and
making intricate cuts.
6. Always start at a slow speed and gradually increase the speed until the optimum cutting
speed is obtained.

located up under the rear of the machine and
should be removed and checked if the
machine does not operate. If the fuse (B) is
