Fig. 8 • Reassembly of the power supply unit and its vicinity
Perform reassembly by reversing the disassembly procedure. However, special attention should be given
to the following items.
1. Reassembly of the power supply unit and its vicinity
(1) Perform wiring according to the connecting diagram on page 9 when replacing the Switch [39] or Stator
Controller (D) Set [33] with new one.
(2) Connect the internal wires of Stator Controller (D) Set [33] to the Switch [39] paying attention to the
colors of the internal wires. Then secure them with the four Screws M3.5 x 5 [40] .
(3) Be careful not to get the internal wires caught in the power supply unit.
2. Reassembly of the impact mechanism
(1) Mount the Hammer Washer [13] , Spring [14] , Spring Seat [15] , and Spindle [20] in this order into
Hammer (D) [11] , which contains the thirty-eight Steel Balls D3.97 [12] .
(2) Match the peak of the cam groove of the Spindle [20] with the steel ball insertion groove of Hammer
(D) [11] . Use a hand press or similar tool to press the raised portion of Hammer (D) [11] so as to
compress the Spring [14] until it contacts the Spindle [20] , and then hold it there.
(3) Put the two Steel Balls D7.14 [10] in the steel ball insertion groove. Check that the Steel Balls D7.14
[10] are in the cam groove, and then release the hand press.
(4) Mount the Idle Gear Set (2 pcs.) [21] and the two Gear Shafts [19] on the Spindle [20] .
3. Reassembly of the main body
(1) Secure the stator to Housing (D) [34] with the two Screws D4 x 60 [32] and insert the controller PCB
ass’y (D) into the lower portion of the stator.
(2) Mount the Cord Clip [47] with its protrusion toward the cord, and then secure it with the two Screws D4
x 16 [46] .
(3) Position the internal wires under the Switch [39] .
NOTE: Position the internal wire of the noise suppressor PCB on the right, and the internal wire
of the power supply PCB on the left. Position the green and yellow internal wires of the
switch on the right, and the blue and black internal wires on the left. Then insert the
Switch [39].
