8. Check that blade teeth point forward and down
toward table.
9. Try moving blade by hand to make sure it is
secure. Pluck the blade with your finger, as you
would a guitar string – it should emit a clear note if
properly tensioned.
TIP: If changing a blade while cutting fretwork, you
may first push blade through pilot hole in workpiece,
then install blade to saw. See Figure 14. This prevents
having to raise the arm for the first cut.
Figure 14: Installing Blade with Workpiece
Adjusting Blade Tension
If blade refuses to be clamped tightly according to the
above steps, one or both of the following adjustments
may be needed (Figure 15):
•
Upper clamp spring pressure can be adjusted by
lifting handle (D) to vertical position. Rotate handle
clockwise one turn to increase pressure, then
push handle into clamping position. Note: Too
much handle rotation will prevent clamping.
•
Turn set screws (G) with 3mm hex wrench
clockwise to reduce gap between clamping
surfaces.
Figure 15: Tension Adjustment
Either of the above steps should resolve blade tension
problems. If problem still exists:
•
Rotate arm adjustment knob (Figure 16) clockwise
by hand. This will raise arm and apply more
tension to blade.
IMPORTANT
: Rotating arm adjustment knob for
tension purposes should only be done if absolutely
needed, as it will affect later blade oscillation
settings. See
Adjusting Blade Oscillation,
page 21.
