<8> Assembling cord
Hold the cord with labyrinth figured lead holder as illustrated in Fig. 8.
Fig. 8
Cord has to be passed through
cord guard.
<9> In case of damaged varistor or fuse, they can be repaired according to the following procedure without
replacing the circuit board.
(1) How to find broken varistor
a. In case that the surface of varistor (ref. to the following illustration) has broken or has become black, and
fuse has been cut, the varistor has been damaged.
b. Varistor can be damaged easily, if the charger is plugged in a double voltage of the rating one.
c. It is considered that the varistor has been broken for other reasons, if the fuse is broken while the surface
of varistor is not damaged. In this case charging circuit complete has to be replaced.

(2)Removing broken varistor
A. Cut the lead wire of varistor at the height
of about 10mm from the surface of urethane resin.
B. Take off lead wire's sheath by 2-3mm
with nipper to expose the core.
Cut approx. by 10mm
2-3mm
(3)Assembling new Varistor (See Fig. 12)
a. Cut new varistor's lead wires to 10 mm, and insert
them about 5mm depth between the sheath
and the core.

Fig. 11
b. Solder both lead wires, being so careful that they
may not contact with each other.
Approx. 10mm
Insert about 5mm depth.
Solder here.
