(d) Mount the DC-Speed Control Switch [36] <33> to housing (A) so that the protrusion of the forward/reverse
lever at the top of the switch is inserted into the U-shaped groove of the Pushing Button [37] <34>. Apply
silicone grease (KS609, Shin-Etsu Chemical Co., Ltd.) to the contacting surfaces of the FET of the DC-
Speed Control Switch [36] <33> and the Dust Guard Fin [27] <24> then mount them to housing (A).
(Note) The temperature of the FET may be high if the silicone grease is not applied. Make sure that the
three internal wires from the FET are passed above the DC-Speed Control Switch [36] <33> (see
Fig. 16).
(2) Mount the Strap [41] <38> to housing (A) and apply silicone rubber (ThreeBond 1211) to housing (A) as shown
in Fig. 16. Mount housing (B) to housing (A) and secure them with seven Tapping Screws (W/Flange) D4 x 20
(Black) [31] <28>. Wipe the silicone rubber coming out of the housing with a cloth.
Position the plate of the Dust Guard Fin
[27] <24> under the rib of housing (A).
(3) Mounting the mechanical parts
(a) Put Washer (S) [15] <12> onto the shaft of the Spindle [17] <14> and mount the Hammer [11] <8>
containing the twenty-eight Steel Balls D3.175 [12] <9>, Washer (J) [13] <10> and the Hammer Spring [14]
<11> to the Spindle [17] <14>.
(b) Align the top of the cam groove on the Spindle [17] <14> with the steel ball guide groove on the Hammer
[11] <8> as illustrated in Fig. 10. Press down either of the raised faces of the Hammer [11] <8> with a
hand press to compress the Hammer Spring [14] <11> until the end surface of the hammer contacts the
Spindle [17] <14>.
