Perform reassembly by reversing the order of the disassembly procedure. However, special attention
should be given to the following items.
1. Reassembly of the power supply unit
NOTE: Perform wiring according to Figs. 6 and 7 being careful of the internal wiring and the
connecting direction.
(1) Solder the internal wires to the motor and the DC switch according to the following steps (a) and (b)
being careful of the soldering terminals and color of internal wires. (See Figs. 6 and 7.)
(a) Solder the red internal wire of the Internal Wire Ferrite Set [30] to the positive side (red marked
side) of the Motor DC 12 V [23] and the M1 terminal of the DC switch.
(b) Solder the black internal wire of the Internal Wire Ferrite Set [30] to the negative side (opposite to
the red marked side) of the Motor DC 12 V [23] and the M2 terminal of the DC switch.
(2) Push the internal wires of the Switch Terminal Set [33] in the ribs and grooves of housing (A) to
prevent the internal wires from being caught. (See Figs. 6 and 7.)
(3) Fit the protrusion of the forward/reverse changeover lever of the Switch Terminal Set [33] in the hole of
Pushing Button (A) [32], and then mount it to housing (A).
NOTE: Black oxide or separated plating on terminal support contacts to be connected to the
battery will increase the temperature of the contacts and damage the battery or driver body.
Replace the Switch Terminal Set [33] with a new one.
