supporting aids for difficult to handle
workpieces.
Never cut pieces that are too small.
During cutting operation the
workpiece must firmly be pressed
against the table surface.
Do not perform any operation
freehand.
Remove cut and jammed workpieces
only when motor is turned off and the
machine is at a complete standstill.
Do not reach under the scroll saw
table when the motor is running.
Install the machine so that there is
sufficient space for safe operation
and workpiece handling.
Keep work area well lighted.
