ADJUSTING BLADE

TENSION

Tension is applied to the blade when the blade tension lever (A) Fig. 27, is in the rear position, as shown. When the lever (A) is moved forward, as shown in Fig. 28, blade tension is released.

When adjusting blade tension, lever (A) should be in the forward position, as shown in Fig. 28. To increase blade tension, turn knob (B) Fig. 28, clockwise and to decrease blade tension, turn knob (B) counterclockwise. NOTE: It is necessary to adjust the blade tension knob (B) only when the blade is removed from both upper and lower blade holders and a new or different type of blade is assembled to the holders. It is not necessary to adjust blade tension when the blade is removed and replaced in only the upper blade holder as in performing inside cutting operations.

Adjusting the blade for proper tension is usually accomplished by trial and error. One method is to pull back on the blade tension lever (A) Fig. 28, the blade should start to have tension (resistance) when the blade tension lever is half way between open Fig. 28, and closed Fig. 27. Finer blades require more tensioning while thicker blades require less tension.

ADJUSTING CLAMPING ACTION OF UPPER BLADE HOLDER

Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper blade holder. It should be noted, however, that very little adjustment is necessary and very little clamping force is required to hold the blade.

1.Move the chuck locking lever (C) Fig. 23, to the rear (open) position, as shown.

2.Turn locknut (C) Fig. 29, clockwise to tighten and counterclockwise to loosen the clamping action of the, blade holder. Very little movement of locknut (C) is necessary.
