MATERIAL HOLd-dOWN
The material hold-down (F) Fig. 9 should contact the
surface of the workpiece. To adjust the material hold-
down, loosen the thumbscrew (D) Fig. 9 and move the
rod up or down.
The material hold-down must be beveled when the table
is beveled. To bevel the material hold-down, loosen the
hex screw (E) Fig. 9 and bevel the material hold-down
until it is parallel to the table. Retighten the material hold-
down before cutting.
NOTE: When cutting, ensure the material hold-down
does not contact the bottom arm of the scroll saw. Your
scroll saw has a maximum thickness capacity of 2"
(50.8 mm). Do not cut material thicker than 2" (50.8 mm).
NEVER remove the material hold-down since it also
functions as a barrier between fingers and blade.
AIR HOSE
Your scroll saw features an adjustable air (G) Fig. 9 hose
to keep your work area free from dust and debris. Be sure
to position the air hose properly: it should blow saw dust
away from the operator.
SPEEd CONTROL KNOB
Your scroll saw features a variable speed control, from
400 to 1,750 strokes per minute. To operate the variable
speed feature, turn the speed control knob (C) Fig. 8 with
the saw running.
To increase the speed, turn the knob clockwise. The
numbers on the speed control knob represent speed
ranges. One is the minimum speed, 8 is the maximum
speed.
Slower speeds are recommended for metals, plastics,
harder woods and very thin materials.
SAWINg
Hold material firmly against table. Always feed material
toward the blade. Feed the workpiece fast enough to
allow the blade to cut, but do not force material into the
blade too quickly.
BEVELINg
The table of your scroll saw bevels 45° left and right. A
detent is set at 0°. To bevel the scroll saw table, loosen

the bevel lock knob (H) Fig. 10, and bevel the table to the
desired setting on the bevel scale (J), indicated by the
bevel pointer (I).
NOTE:
Before tilting the table for bevel cuts of 45°, check
the clearance around the lower thumbscrew. To facilitate
an accurate 45° cut, the thumbscrew and set screw may
need to change places. On the setscrew side, sufficient
clearance is available.
FRETWORK
INSIdE CUTS
Your scroll saw is ideal for making inside cuts for detail
work. To make an inside cut:
1. Drill a pilot hole in your workpiece.
2. Make sure the blade tension lever is moved fully to
the right
3. Loosen the top thumbscrew blade clamp.
4. Leaving the blade held in place by the bottom blade
clamp, lift the top arm of the scroll saw, as shown in
Figure 11. Thread the saw blade through the pilot hole
in your workpiece and reattach the blade by tightening
the top thumbscrew.
5. Readjust the blade tension and begin the inside cut.
Alternately, you can loosen the bottom thumbscrew blade
clamp in step 3 above, and thread the blade through the
top of the workpiece.
NOTE : Do not lift saw by upper arm. Damage will occur.
