(Fig.3)Note:Set Blade cover in place to prevent being injured as illustrated inFig. 3.3) Remove Gear housing cover by levering with two 1R263 or slotted screwdrivers. (Fig.4)4) Turn crank portion with slotted screwdriver inserted to the groove on Spindle. (Fig.5) Two oval holes of Shear bladesand the crank portion of Gear ass’y have to be aligned as illustrated inFig. 5.Note:It is possible that Two oval holes of Shear blades and the crank portion of Gear ass’y do not be aligned becauseGear ass’y is in locked position by Pin 5. Turn Spindle counterclockwise with strong force to release the lockedcondition. (The spring and the lock washer in Gear ass’y will be slid, and Pin 5 will be out of the locked position.)Fig. 3Fig. 4Blade coverUnder coverM4x25 Pan headscrew (4pcs.)Gear housing coverFront gripFig. 5groove on Spindle of Gear ass’yBlade coverSlottedscrewdriver1R263 or Slotted screwdriver (2pcs.)Tangential lines of Crank portion and straight linesof Shear blades’ oval holesCenter line of Housing setand Shear blade ass’yOval holes ofShear blades(one hole each)90Housing set90Viewed from the upper sideRepair[3] DISASSEMBLY/ASSEMBLY[3] -2.

(Fig.8)Pass the two M5x25 Pan head screws through Shear blade ass’y to align the holes of Shear blade ass’y withSleeves, and tighten the two M5x25 Pan head screws. (Refer toFig. 6.)When reusing two M5x25 Pan head screws, apply adhesive to the threads.When the holes and Sleeves for two M5x25 Pan head screws are not aligned, slide only Guide plate back and forth.(Fig.9)After tightening M5x25 Pan head screws, make sure that Shear blades reciprocates smoothly with turning Crankwith slotted screwdriver.

(Fig.13)Note:Lifter section of UH5580, UH6580 and UH7580 is different from that of UH4570, UH5570 and UH6570.Enlarge the distance between Pin holder and Cap holder using 1R003 with 1R212, and keep Compression spring 5compress to separate the bottom end of Pin 5 from the hole of Gear housing. SeeFig. 14for the detail.7) After removing Brush holders, separate Armature ass’y, Field ass’y, Lever and Gear housing as a assembled part fromHousing L.
