DUST BLOWER
A dust blower (A) Fig. 18, is provided, and can
be moved to direct air to the most effective
point on the cutting line.
ADJUSTING BLADE TENSION
Tension is applied to the blade when the blade tension lever (A) Fig. 19, is in the rear position, as
shown. When the lever (A) is moved forward, as shown in Fig. 20, blade tension is released.
To increase tension on the blade, rotate tension lever (A) Fig. 20, clockwise; to decrease blade ten-
sion, rotate tension lever counterclockwise. NOTE: When adjusting blade tension, the lever (A) Fig.
20, should be in the full forward position.It is only necessary to adjust blade tension knob when a
different type of blade is assembled to the blade holders. It is not necessary to adjust blade tension
when the blade is removed from and replaced in only the upper blade holder, as in performing inside
cutting operations. Adjusting proper tension on the blade is usually accomplished by trial and error;
however, a good method to use is to pluck the rear of the blade like guitar string after the tension
lever is moved to the rear. A high-pitched tone of the blade usually indicates proper tension. Thicker
blades require more tension (a higher pitched sound) while finer blades require less tension.
