6. Insert long end (A) Fig. 16, of quickset blade

changing wrench into hole (G) in lower blade holder. This

will automatically align wrench (C) with blade holder

screw (H).

7. Turn wrench (E) Fig. 17, counterclockwise to loosen

screw (H) and remove blade (F) from lower blade holder.

8. Insert new blade into the lower and upper blade

holders in the same manner, making certain the blade

teeth are pointing down toward the table. Replace table

insert.

9. Apply blade tension by referring to the section

“ADJUSTING BLADE TENSION”.

ADJUSTING

BLADE TENSION

Tension is applied to the blade when the blade tension

lever (A) Fig. 18, has been adjusted and is in the

horizontal position as shown. When the blade tension

lever (A) is moved to the vertical position, as shown in

Fig. 19, blade tension is released.

To adjust blade tension, position lever (A) in the vertical

position, as shown in Fig. 19. To increase tension, turn

lever (A) clockwise and to decrease tension turn lever (A)

counterclockwise. When adjusting tension, turn lever

one-quarter of a turn at a time. NOTE: It is necessary to

adjust the blade tension only when the blade is removed

from both the 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. After desired

tension is obtained, position tension lever (A) in the

horizontal position, as shown in Fig. 18.

Adjusting the blade for proper tension is usually

accomplished by trial and error; however, a good method

to use is to pluck the rear of the blade like a guitar string,

after the tension lever (A) is moved to the horizontal

position, as shown in Fig. 18. A high-pitched tone of the

blade should be heard and this usually indicates proper

tension. Finer blades require more tensioning (a higher

pitched sound) while thicker blades require less tension.
