FUSE REPLACEMENT
A fuse holder (A) Fig. 36, and fuse (B) are 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 bad, replace it with a 4 amp fuse.

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.
