B. Additional wiring work
General internal wiring can be accomplished by referring to paragraphs 8 and 9. The following are special
instructions for switch connection.
(1) Wiring of reversing switch
Insert the lead wire (black) coming from the stator into the terminal (4) of the reversing switch, and the
lead wire (white) into the terminal (3) as shown in Fig. 20. Insert the lead wire (brown) coming from the
carbon brush or choke coil into the terminal (2) and the lead wire (blue) into the terminal (1). After the
insertion, pull each lead wire slightly to check the lead wires do not come off. To disconnect the lead
wires, insert a small flat-blade screwdriver into the windows near the terminals and pull out the lead
wires.
(2) Wiring of speed control switch
Insert each cord into the terminal (1 ) and terminal (2 ) of the speed control switch as shown in Fig.
21 and tighten the screw (tightening torque: 0.6 ± 0.2 N
٠
m (6 ± 2 kgf
٠
cm, 5.2 ± 1.7 in-lbs.)).
Insert the lead wire (gray) coming from the stator into the terminal (M1) and the lead wire (red) into the
terminal (M2). Insert each lead wire (white) coming from the noise suppressor into the terminal (C1) and
(C2). After the insertion, pull each lead wire slightly to check the lead wires do not come off. To
disconnect the lead wires, insert a small flat-blade screwdriver into the windows near the terminals and
pull out the lead wires.
