7�2�6 LEDGER BLADES:
Each machine is equipped with a ledger (stationary) blade that acts as a shear for the moving rotor
blades.
The ledger blade is located on the lower rotor housing, mounted on slotted holes for adjustment. There
are 4 usable corners on the blade, when the corner facing the rotor blade rounds over, remove the blade
and re-install with a different corner facing the rotor blade. It is recommended that the clearance between
the rotor and stationary blades be
set and maintained at 1/32 to 1/16"
(.76 - 1.52 mm) to obtain the best
performance.
