VARIABLE SPEED CONTROL AND
ON/OFF SWITCH

the switch "OFF" when the scroll
saw is not in use. Also, in the
case of power failure (all of your
lights go out) push the knob
"OFF". Remove the plug from
the power source outlet to avoid
accidental starting.
The variable speed control allows
greater versatility to cut a variety
of materials such as wood,
plastics, non-ferrous metals, etc.
Depending on the hardness and
thickness of material, the speed
should be reduced to allow
the blade teeth to remove cut
material from the kerf.

RECOMMENDATIONS FOR CUTTING
1. When feeding the workpiece into
the blade do not force the leading
edge of the workpiece into the
blade because the blade will
deflect, reducing the accuracy
of cut and possibly breaking the
blade. Allow the saw to cut material
by guiding the workpiece into the
blade as it cuts.
2. The blade teeth cut material ONLY
on the down stroke.
3. You must guide the wood into the
blade slowly because the teeth of
the blade are very small and they
