storage should 'not exceed two years since their delivery.
The used batteries should be wiped clean fully chargedb~fore
being put aside separately- Moreover, they should be checked and
recharged once a month.
If the used batteries are taken out 'of service for a long period
of time, (more than 6 months) ,they should be stored witllout elec-
trolyte. Therefore, it is necessary to discharge them with one
twentieth of rated current until the voltage of each cell is lower
than 1. 7 volts, and then drain off the electorlyte ,'and flush them
with distilled water(once enery 3 hours) until the water is free of
acidity. Finally ,dry them up and store them as the new batteries.
F. Safety operation: The place where the batteries are charged
should he well ventilated and free of fire. When the electrolyte is

added into dis'tilled water ,and- never 'add the wate-r to the ·acid·.
CZ)Maintenance of the generator
A·. During inspecting and servicing ·the generator, never test
its insulation with a megaohm meter <ha.nd winding meter) of with
the 220 volts A. C. power source. Only a multimeter with high in-
ternal resistance can be used such purpose.
B. The generator should be inspected once every 750 operating
hours (It is allowed according to the o'perating condition, that the
generator may not be serviced until- the fourth order
maintenance) .
(3)Miantenance of Starting Motor
