Figure 26: outside curve cutting
For fretwork (inside cutting):
1. Drill pilot holes in workpiece just large enough
for blade insertion.
2. Release clamp lever (D, Figure 27) and raise
arm.
3. Guide blade through pilot hole in workpiece.
4. Lower arm and tighten clamp lever (D).
5. Hold workpiece tightly against table and turn on
saw. Set speed using variable control knob.
6. Smoothly guide workpiece into blade, using
light pressure. Avoid coming to a complete stop
while cutting.

11.0 User-maintenance

Always unplug scroll saw from
power before performing maintenance. Failure
to comply may result in serious personal injury.

11.1 General maintenance

Clean wood dust from the saw frequently, using a
vacuum or compressed air, or damp cloth. Use a
soft bristle brush for crevices.
Use proper eye and respiratory
protection if using compressed air.
Keep the table clean. Periodically apply a light coat
of paste wax or spray protectant to the table to
prevent rust and maintain a smooth surface.
When finished cutting, release blade from upper
clamp to remove unneeded tension on clamp
spring. Remove blade if saw will be stored for longer
periods.
Periodically inspect the prongs of the lower spring
plate (see E, Figure 15). Bend upward slightly if
needed to ensure a firm grip upon lower blade
holder.

11.2 Lubrication

Periodically apply light dabs of grease to front and
rear trunnions (Figure 28) where parts slide against
one another.
Bearings in the drive mechanism are pre-lubricated
and sealed; no further attention is needed for these.

11.3 Fuse inspection

The scroll saw is equipped with a 5-amp fuse for
overload protection. If the saw stops working,
inspect fuse:
1. Unscrew fuse cap (Figure 29) and pull fuse out
of cap.
2. If fuse has blown, replace it.
3. Install new fuse into cap, then screw cap into
hole.
