on the cover should be kept un-clogged, and battery outer surface should be kept clean and dry.
After discharging, the battery must be re-charged within 24h, to avoid sulfuration on plate
electrode, and long time delay is prohibited. If the battery needs be stored for long time, then it
should firstly be fully charged (i.e., Battery should be so charged that inside it air-bubbles occur).
Later, the battery should be re-charged once a month. When the battery is being stored, never pour
out the electrolyte.
2. Charging generator
It is a silicon rectified shunt-excitation generator. It consists of 3-phase a.c. generator and
silicon diode rectifier. Negative pole is grounded (i.e., connected to iron). Do not mistake the
polarity, or the generator will be damaged.
For use and maintenance of the generator, refer to
《
Operation and Service Manual for JF
Series Silicon Rectified Excited Generator
》
3. Regulator
JF11A generator is matched with FT111 voltage regulator. When the speed of generator
changes, a regulator can automatically stabilize the output voltage of generator within specified
range, automatically limit load current, and automatically switch on/off the electric circuit of
battery and generator.
When installing the regulator, it should be vertically placed, with its two terminal posts
downward, and with its wiring being correct and reliable. As regulator is a precise device, its
working clearance should not be arbitrarily adjusted. For its inspection and adjustment, it is
possible to refer to
《
Operation Manual for FT111 Regulator
》
4. Starting motor
It is series-excited d.c. motor.
The engagement between the starting motor and engine flywheel gear-ring is controlled
electro-magnetically. When the starting switch is turned on, electromagnetic switch makes
gearwheel to be engaged with gear ring, and at the same time the circuit of starting motor is
switched on, thus driving the flywheel.
After the engine is started, immediately turn off the starting switch. The iron core, under the
action of spring, will drive the gear to go back to original place. Each continuous duration period
for the use of starting motor must not exceed 5s. Interval between every two starts should be more
than 2 min. If three successive starts all fail, then it is necessary to inspect and eliminate faults.
5. Ignition switch
Ignition switch has 3 positions. Middle position means the circuit(s) is completed cut off.
When turn the key clockwise, turn on the starting switch and regulator, now the engine can be
started. After the engine is started, turn the key anticlockwise to the end. At this moment, only
