Shear blade ass’y and Gear complete [1] NECESSARY REPAIRING TOOLS CAUTION: Unplug the machine for safety before repair/ maintenance ! 1) Turn the machine upside down and keep it in a horizontal position by the use of a horizontal portion of Front grip. 2) Remove four M4x25 Pan head screws and Under cover. (Fig. 1) Note: Set Blade cover in place to prevent being injured as illustrated in Fig. 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 blades and the crank portion of Gear complete have to be aligned as illustrated in Fig. 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 place without 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. (Fig. 5) Note: Do not lose two Flat washers 8.

2) Remove two M5x30 Pan head screws, and then slide the following parts together the forward direction. (Fig. 8) *Switch lever B *Front grip *Protector complete The above parts can be pulled out from Housing set. 3) Remove ten 4x18 Tapping screws and separate Housing R from Housing L. (Fig. 9) Carbon brushes, Switch and Power supply cord can be removed at this time. 4) Remove Switch lever A with Compression spring 5, Switch lever C with Rod and Link, and Switch from Housing L. (Fig. 10) (The position of Switch interferes with disassembly of Lifter section.) 6) Remove Lifter section, Brush holders and Carbon brushes from Housing L. And then, remove Armature, Lever and Gear housing complete as an assembled part. (Fig. 11) [3] DISASSEMBLY/ASSEMBLY [3] -1. Shear blade ass’y and Gear complete (cont.) [3] -2.

Note: Regarding the new Shear blade ass’y; - make sure that the routes for the two M5x25 Pan head screws are secured. - pass two M5x25 Pan head screws through the holes for Shear blade ass’y in advance. Do not forget to mount two Flat washers 8 to the shaft ends of Gear complete. (Fig. 5) The flat shape of Dust guard has to be inserted into the groove of Gear housing complete before putting Shear blade ass’y on Gear housing complete. (Fig. 6) Pass the two M5x25 Pan head screws through Shear blade ass’y to align the holes of Shear blade ass’y, and tighten the two M5x25 Pan head screws. (Refer to the previous page.) When reusing two M5x25 Pan head screws, apply adhesive to the threads. When the holes for two M5x25 Pan head screws are not aligned, slide only Guide plate back and forth. (Fig. 6) 3) After tightening M5x25 Pan head screws in the step 2), make sure that Shear blades reciprocates smoothly with turning Crank with slotted screwdriver. (Fig. 7) Housing R

Note: 1) When setting Armature and Gear housing complete in place, pass Lever through Field at the same time while inserting the hinge portion of Lever into Housing L carefully because the hinge tends to remove. (Fig. 12) Insert the hinge portion of Gear housing complete into Housing L as well. 2) When Armature, Gear housing complete and Lever are set in place, Ball bearing 6000ZZ on Fan side of Armature has to be partly exposed from Gear housing complete as illustrated in Fig. 13. A part of Ball bearing 6000ZZ has to be exposed from Gear housing complete.
