ADJUSTING BLADE TENSION
See Figure 9.
 Turning the blade tension knob counterclockwise
decreases (or loosens) blade tension.
 Turning the blade tension knob clockwise increases (or
tightens) blade tension.
NOTE: Adjustments to blade tension can be made at any
time.
Check tension by the sound the blade makes when plucked
like a guitar string. This method of adding tension to the
blade can be developed with practice and requires knowing
the scroll saw.
 Pluck the back straight edge of blade while turning ten-
sion adjusting knob. Sound should be a musical note.
Sound becomes less flat as tension increases. Sound
decreases with too much tension.
NOTE: Be careful not to adjust blade too tight. Too much
tension may cause the blade to break as soon as you start
cutting. Too little tension may cause the blade to bend or
break before the teeth wear out.
WARNING:
Do not allow familiarity with products to make you care-
less. Remember that a careless fraction of a second is
sufficient to inflict serious injury.
WARNING:

shields when operating power tools. Failure to do so
could result in objects being thrown into your eyes
resulting in possible serious injury.
WARNING:
Do not use any attachments or accessories not
recommended by the manufacturer of this product. The
