(c) Power supply unit (Fig. 33)
Mount the power supply unit assembled according to the above step (1) to Housing (A) [2]. Connect the
internal wires of the Switch Ass'y [14] locating the blue internal wire at the upper position and the brown
internal wire at the lower position. (Housing (A) [2] and Housing (B) [2] are indicated with "+" and "---"
respectively. Be sure to connect the brown internal wire to the "+" side and the blue internal wire to the "---"
side. Otherwise the Switch [13] can be broken.) Then mount the Switch Holder [12] being careful of the
direction.
(d) Mount the Pushing Button [3] mating its groove to the lever of
the Switch [13] (Fig. 34).
(e) Mount the Spring [4] to the Pushing Button [3] (Fig. 33).
(f ) Mount the Wrench Holder [7] to Housing (A) [2] (Fig. 33).
(g) Place the internal wires to the proper positions in Housing (A)
[2]. Secure Housing (B) [2] with the nine Tapping Screws (W/
Flange) D4 x 20 (Black) [8] being careful not to catch the
internal wires.
(h) Mount the Hook [6] in the proper direction.
Mount the Retaining Ring (E-type) for D4 Shaft [10] (Fig. 35).
(3) Reassembly of the bracket ass'y section
(a) Lubrication (Fig. 36)
Sufficiently apply grease to Bracket (A) [42], Bracket (B) [44], Roller (A) [53],
Cam Shaft [55], coupling portion and rotating portion of Bolt (A) [39] because high loads are applied to these
parts. Also apply grease to the inner circumferences of the punched holes of the Return Plate [41] and the
sliding portions of the Return Spring [18] and Bracket (A) [42]. Apply TUFREX 251 grease to the shafts, holes
and surfaces indicated with diagonal lines and two-dot chain lines in Fig. 36. Carefully apply grease to the
inner circumference of the hole of Roller (A) [53] until the grooves in the hole are completely greased.
(b) Mounting Roller (A) [53]
Check the position of the smaller diameter end of the Roller Pin [54] and insert the Roller Pin [54] in the hole
of Bracket (A) [42] in the proper direction as shown in Fig. 36. Align Roller (A) [53] with the hole of Bracket (A)
[42] and press-fit the Roller Pin [54] until it becomes flush with the end surface of Bracket (A) [42] (Fig. 36).
