2 DISASSEMBLY & ASSEMBLY PROCEDURE
Refer to the “DISASSEMBLY DIAGRAM”.
2.1. DIASSEMBLY PROCEDURE
1. Remove the battery lid unit (Ref. No. 18).
2. Unscrewed 4 screws (B16 - B19), and then remove the shoe unit (Ref. No. 43).
3. Remove the side rubber 1 (Ref. No. 26) and side rubber 2 (Ref. No. 27).
4. Unscrewed 4 screws (B7 - B10), and then remove the main case (C) (Ref No.3).
Caution
· Be careful of the high voltage capacitor (Ref No. C3) when servicing.
· Be sure to discharge the capacitor (Ref No. C3) to use the resistor for discharging (ERG5SJ102) after connecting
between cathode of Ref No. D2 and battery terminal (-).
5. Remove the insulation sheet (Ref No. 24), and then unscrewed 3 screws (B3 - B5) with the battery case (Ref No. 14) is holding
to up slightly. Remove the C.B.A. (A) and C.B.A. (B)..
6. Remove the 2 locking springs (Ref No. 44-1 and 44-2), and then unscrewed 2 screws (B20 and B21). Remove the main case
(B) (Ref No. 2).
2.2. ASSEMBLY PROCEDURE
2.2.1. Assembly of the Dial Knob (Ref No. 8-1 and 8-2)
Apply the grease to the operation part of main case (D) (Ref No. 4) when assembling the click spring (Ref No. 10-1 and 10-2).
2.2.2. Assembly of the C.B.A.
When assembling the C.B.A., apply the grease to foil side of C.B.A. (A) where is located to jack spring and dial brush terminal after
alcohol cleaning.
2.2.3. Assembly of the Main Case (B)
Apply the grease to the part of click mold (Ref No. 16) is touched to the main case (B) (Ref No. 2), and then install to the main case
(A) (Ref No. 1). Screwed 2 screws (B20 and B21).
2.2.4. Installation of the Photo Transistor
Install the photo transistor (Ref No. PT2) to C.B.A. (A), and then confirm capacitor (Ref No. C11) is installed to the side of reflection
umbrella to the main case (B) (Ref No. 2).
Install the photo diode (Ref No. PD1), and then confirm it to the battery case side of main case (C) (Ref No. 3).
Install the photo transistor (Ref No. PT1), and then confirm it to the side of shoe unit.
2.2.5. Layout of lead wire
The lead wire for SLAVE (black) and lead wire for AUTO (red and black) is located between the insulation sheet and C.B.A. (B).
