Reassembly can generally be conducted by reversing the disassembly procedure. However, special
attention should be given to the following items.
1. Reassembly of the power supply unit
Perform wiring according to the wiring diagram (Fig. 2). Pay attention to the direction in which to connect
the internal wires and terminals.
(1) Solder the internal wire (white) coming from the top of the Controller Terminal Set [46] to the (B-)
terminal of the DC-Speed Control Switch [50]. Then solder the internal wires (brown and red) coming
from the top of the Controller Terminal Set [46] to the (B+) terminal of the DC-Speed Control Switch
[50] (Fig. 2).
(2) Solder the internal wire (red) coming from the Brush Block [38] to the (M2) terminal, and the internal
wire (black) to the (M1) terminal of the DC-Speed Control Switch [50] (Fig. 2).
