Remove the Special Screw M5 [43] <40> with a flat-blade screwdriver or a coin and remove the Hook Ass'y
[39] <36> and the Hook Spring [42] <39>.

Remove the seven Tapping Screws (W/Flange) D4 x 20 (Black) [31] <28> from the main body. Before
removing Housing (B), be sure to remove the Brush Caps [30] <27> because Housing (B) cannot be removed
if the Brush Caps [30] <27> are mounted.
(7) Remove the FET of the DC-Speed Control Switch [36] <33> from the Dust Guard Fin [27] <24>. Then, the
Inner Cover [24] <21>, Armature ass'y [25] <22>, Magnet [26] <23>, Brush Block [28] <25> and DC-Speed
Control Switch [36] <33> can be removed in a piece. The Pushing Button [37] <34> and the Strap [41] <38>

Switch [36] <33>.
(Note) Do not disconnect the three FET internal wires soldered to the DC-Speed Control Switch.
(9) Removal of the Magnet [26] <23> and the Dust Guard Fin [27] <24>
Remove the Magnet [26] <23> in the "B" direction (see Fig. 8) holding the Inner Cover [24] <21> securely
because the Magnet [26] <23> has a strong magnetism. The Dust Guard Fin [27] <24> can be easily
removed from the Magnet [26] <23> by pulling it in the "B" direction (see Fig. 11) because it is mounted to the
Magnet [26] <23> magnetically.
