The primary charging assembly is used here as an ex-ample.1) Remove the shield plate [1].- 2 screws [2]- 1 holder [3]F-7-2652) Remove the wire cleaner.3) Loosen the charging wire [2] about 5 cm from the charging wire reel [1]of wire diameter 0.06 mm, and make a loop of diameter 2 mm on the edge.MEMO:When making a loop, roll the charging wire in the hex key once, and roll thehex key three to four times to twist the charging wire. By doing so, you caneasily make a loop.4) Cut the edge of the twisted charging wire (excess wire) using a wire cutter.5) Hook the loop on the stud [3].F-7-2666) Hook the charging wire [2] on the charging wire positioning [1] at rearside, and then, hook the charging wire tension spring [3] to the chargingwire at the position indicated below and twist it.[1][2][3][1][2][3][3][1][1] [2][2] [3][1][2][3](FRONT) (REAR)
