(Fig.1)Note:Set Blade cover in place to prevent being injured as illustrated inFig. 1.3) Remove Gear housing cover complete by levering with 1R263 or slotted screwdriver. (Fig.2)4) Turn crank portion with slotted screwdriver inserted to the groove on Spindle. (Fig.3)Two oval holes of Shear bladesand the crank portion of Gear complete have to be aligned as illustrated inFig. 3.5) Loosen two M5x25 Pan head screws (threadlocker type) and separate Shear blade ass’y from the machine. (Fig.4)Note:1. Leave the two M5x25 Pan head screws in their holes of Shear blade ass’y when setting Shear blade ass’y in placewithout disassembly.Removing two M5x25 Pan head screws may cause misalignment of holes of the components of Shear blade ass’y.2. Leave Dust guard in the groove of Gear housing complete.6) Pull out Gear complete from Gear housing.
