(7) Removal of Housing (B) [35]
Remove the seven Tapping Screws (W/Flange) D4 x 20 (Black) [32] and a Machine Screw (W/Washers)
M4 x 25 [46] from the main body. After removal of the Machine Screw (W/Washers) M4 x 25 [46], the Strap
(Black) [44] and the Sleeve [45] can be removed. Before removing Housing (B) [35], be sure to remove the
Brush Caps [31] because Housing (B) [35] cannot be removed if the Brush Caps [31] are mounted.
(8) After removal of Housing (B) [35], Inner Cover [25], Armature DC 14.4V [26], Magnet (C) Ass'y [27], Brush
Block [29] and DC-Speed Control Switch [38] can be removed in a piece. The Pushing Button [39] can also
be removed. The FET of the DC-Speed Control Switch [38] is firmly inserted in the housing. To remove the
FET easily, raise the piece of Inner Cover [25], Armature DC 14.4V [26], Magnet (C) Ass'y [27] and Brush
Block [29] from the housing. At this time, be careful not to break the three legs coming from the FET to avoid
malfunction of the switch.
(9) Removal of the switch assembly
Remove the two Machine Screws (W/SP. Washer) M3 x 5 [37] that secure the flag terminal and then
disconnect the internal wires (purple and black) of the Brush Block [29] from the DC-Speed Control Switch
[38].
(Note) Do not disconnect the three FET internal wires soldered to the DC-Speed Control Switch [38].
(10) Removal of Magnet (C) Ass'y [27] and the Dust Guard Fin [28] and Washer (M) [51]
Remove Magnet (C) Ass'y [27] in the "B" direction (see Fig. 8) holding the Inner Cover [25] securely because
Magnet (C) Ass'y [27] has a strong magnetism. The Dust Guard Fin [28] and Washer (M) [51] can be easily
removed from Magnet (C) Ass'y [27] by pulling it in the "B" direction (see Fig. 8) because it is mounted to
Magnet (C) Ass'y [27] magnetically.
