Description L
Charger
CONCEPTION AND MAIN APPLICATIONS H
This charger can charge 1.3Ah Ni-Cd.batteries of 7.2V and 9.6V approx
in 60 minutes.
Its brief benefits and features are as follows.
W
* The charging time is kept in the steady level by controlling the
out put current ( current for charging battery) in spite of the changeable
input voltage (power source voltage).
The end of charging process is recognized by thermostat.
The Ni-Cd.batteries with high capacity (over 1.7Ah) and all of
Ni-MH. batteries can not be charged with this charger. Dimensions : mm ( " )

Repair P2/2
<1> The circuit board can not be repaired, because the circuit itself are molded on the board
with the urethane resin.
It has to be replaced completely with new one.
<2> 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 circuit board has to be replaced.

When removing varistor, melt this part with soldering iron
and remove varistor.
b. Assemble new varistor to the circuit board by soldering.
c. Cut the surplus of varistor's wire with nipper.
