ADJUSTING BLADE TENSION
See Figures 16 and 17.
■ Turn off and unplug the saw.
WARNING:
Failure to unplug your saw could result in accidental
starting causing possible serious personal injury.
■ Tension adjusting knob is on the top of the saw.
See
Figure 17.
Rotate the quick release knob (outer, larger
knob) 1/4 turn to the left or counterclockwise to release
blade tension.
■ Turn tension adjusting knob (upper, smaller knob) to the
right or clockwise to increase tension. Turn it to the left or
counterclockwise to decrease blade tension.
Note: Adjustments of blade tension can be made at any-
time. The quick release knob can be either released
or engaged while making adjustments with the ten-
sion adjusting knob.
■ Rotate quick release knob to the right or clockwise 1/4
turn to engage tension before using the scroll saw.
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 your
scroll saw.
■ Pluck the back straight edge of blade while turning
tension 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 over tension the blade. Too much
tension may cause blade to break as soon as you start
cutting. Too little tension may cause blade to bend or
break before teeth wear out.
