and lower blade holders by pulling forward on blade and
then lifting the blade through the access hole in the table.

workpiece, the teeth of the blade used on the scroll saw
should always point downwards when installed.

the access hole in the table and hook the blade pin in the
pin recess in the lower blade holder. Silde the top blade
pin into the pin recess of the inner upper blade holder. You
may need to press down lightly on the upper blade holder
to install the blade.
■ Carefully tighten the blade by rotating the blade tension
knob clockwise just untill you feel the slack in the blade
removed. Double check to see that the pins are properly
located in the blade holder. Then turn the blade tension
knob ONE full turn clockwise. This amount of blade pressure
