holder slot (12-Fig. I) and then tighten the quick
release tension lever (1-Fig. J).
NOTE: Apply slight downward pressure against the
upper arm (3) when installing the blade into the
upper blade holder. (Fig. I)
5. Tighten the tension on the blade by turning the
tension knob (2) clockwise. Check the tension the
blade. If too loose, turn knob clockwise. Do not make
it too tight or blade will easily break in used. (Fig. J)
NOTE: The quick release lever must always be down

release lever upward only during blade changing
operations. If the blade is over-tightened, the lever will
be difficult to lower and could result in damage to the
blade holder or arm assembly.
