Ledger blades are located on the lower rotor housing,
mounted on slotted holes for adjustment. There are
four usable corners on the blade. When the corner
facing the rotor blade rounds over, remove the blade
and re-install so a different corner is facing the rotor
blade.
Place machine in Safe Condition (See
