OPERATION
A. Blade installation in the blade holder
Place the blade holder in the oblong slot in the base
(right side of the saw base near the front.) Slide the
bottom of the blade (direction the teeth point) between
the two halves of the holder to the center screw. (Run
your finger across the teeth to determine the direction
the teeth point.) Center and secure using a 5/16 open
end wrench. (See Figure 1)

B. Blade installation in the saw (See Figure 2)
Place the quick change holder rod in the slot of the
upper arm behind the quick change blade holder. Slide
the blade up from the bottom thru the hole in the
center of the table. Pull the blade up until the holder
is at the bottom of the lower arm. Slide the blade and
holder back in the lower arm slot until the holder rests
in the V at the bottom of the lower arm between
the arm and clip.
Pull the upper arm down until the upper arm blade
holder assembly will slide over the blade (it may be
necessary to loosen the adjusting handle at the rear
of the saw to allow the upper arm to come down).
Center the blade in the blade holder and slide upward
to the screw. (See Figures 1, 2 & 3)

Using the Allen wrench supplied, left side in the rub-
ber grommet, secure the blade at the top.
Remove the quick change blade holder rod. Center
the tension adjusting rod and lock cam handle. Blade
has a ring like a guitar string when plucked.
Fordifferent blade length adjustments, hold the ten-
sion adjusting rod with a pair of pliers and tighten or
loosen the nut at the lower end of the rod. When the
blade is tensioned the rod should be to the top of
the round handle pivot at the top. (See Figure 3)

C. Sawing (Remember, let the saw blade do the work)
Feedthe material to be cut slowly into the saw blade
while maintaining downward pressure. (This may be
done by hand or by adjusting the holddown foot on
the material.) Note: Always keep hands away from the
saw blade and out from under the moving arm.
D. Using a guide board to saw a straight line (See Figure
4
It is necessary to angle your guide board approx. 4°
from right to left. This is necessary due to the manufac-
ture of all scroll saw blades with a small amount of
set on one side of the blade only.

E. Sawing inside cuts (See Figure 5)
To saw inside cuts, drill a hole in the board, in the
area to be cut out, slightly larger than the blade you
are using. Remove the blade from saw top arm. Loos-
en the handle at the rear of the arms and capscrew
holding blade in holders. Insert the blade up through
the hole drilled in your board and back into the blade
holder. (See blade installation for more details). This
allows quick and easy inside cuts to be made.

and point the tube at a point where the saw blade comes
thru the table and secure. It may be necessary to bend
the attaching bracket to get the proper location.

VARIABLE SPEED ADJUSTMENT
CAUTION: SAW MUST BE RUNNINGTOCHANGESPEED.
Toincreasethe strokes/minute, turn the adjusting knob
(on the right side of the saw base) counter clockwise.
Toreducethe strokes/minute, turn the adjusting knob clock-
wise. NOTE: Saw must be running to change speed. Your
saw was pre-set at the factory at 550 strokes/minute mini-
mum and 1550 strokes/minute maximum. (Figure 6)
e
FIGURE 6
After a period of use the belt may stretch and the
slow strokes/minute cannot be attained. It will then be
necessary to adjust the belt drive. To check first, turn
on the machine and turn the adjusting knob clockwise
until the adjustable pulley is together. Turn off the machine
and disconnect the electrical source. Takehold of the top
and bottom of the V-Belt and squeeze them together. If
it spreads the two halves of pulley on the motor, the motor
needs to be adjusted rearward to take up this slack and
retightened. This will again have the proper belt pulley
relationship for the minimum strokes/minute. There are
four bolts holding the motor which must be loosened to
slide the motor for the belt adjustment, then retightened.
