shows normal specific gravity of the
electrolyte.
5) The accumulator should always
being charged. Check voltage of the
accumulator if engine is hard to start.
Charge additionally, if it is detected
that specific gravity of electrolyte is
lower than 1.18~1.20, otherwise, bat鄄
tery plate will be vulcanized and it will
reduce lifespan of the accumulator.
Additional charging should be kept
for 13~16 hours, and it can take in 1/
10 of capacitance into battery. Cut
down the charging current by half af鄄
ter single cell爷s voltage reaches 2.4V,
and the charging time should be 3~5
hours. When the specific gravity of
electrolyte don爷t rise any more, and
this situation keeps for 2 ~3 more
hours, it indicates that the accumula鄄
tor has been charged fully. Table 2
shows the relationship between tem鄄
perature and the corrected specific
gravity value of electrolyte.
6) Protect the joint of terminal post
and wire from dirt and looseness, or
the terminal post will be burnt out. Af鄄
ter tightening the joints, apply a
Vaseline coat on the terminal post
that can protect the joints from rust
and loose contact, so that engine
can start easily.
7) If left unused for a long time, the
accumulator should be removed and
preserved in a place where is dry,
shady, cool, and ventilative Addition鄄
al charging should also be done ev鄄
ery month.
渊IV冤sensor
3. Oil pressure alarm device
1. Fuel level gauge sensor.
The fuel level sensor adopts sliding-
resister type. Floaters rise and drop
with the oil level changing, which
causes the resister to connect or
short-circuit to make the electromag鄄
netic fuel level gauge change. Con鄄
nect terminal of the fuel level alarm
lamp with the indicator light to indi鄄
cate the lowest fuel level.
2. Water temperature gauge sensor
The temperature sensor is a thermis鄄
tor that is mounted in water jacket to
indicate temperature of cooling water
and it matches with the water tem鄄
perature gauge on instrument board.
The water temperature sensor has a
used as dimmer light. When running
in night, turn on the high-beam light
to lighten the road, but switch to dim鄄
mer light when two vehicles pass
each other.
2. Small light Two small lights are in鄄
stalled on both corners of the front
panel; when park in foggy weather or
run on bright road, in which situation,
headlights should not be turned on,
turn on the small lights to indicate
position and size of the vehicle.
3. Fog lamp When run in fog or park,
In order to lighten the road clearly
and indicate position of the vehicle,
the fog lamp should be turned on,
and the fog lamp is installed on both
ends of the bumper.
4. Ceiling lamp Ceiling lamp is in鄄
stalled on cab ceiling, when used for
driving lighting, ceiling lamp inte鄄
grates with inner rear vision mirror,
so that, except for cab lighting, the
situation behind the vehicle also can
be watched.
渊芋冤Accumulator
1. Brief introduction
1冤General
Accumulator equipped to trucks of
this series is aneroid and sealed by
a plastic case, and it has a big ca鄄
pacity as well as a light weight.
2. Use & Note
1) Keep the case clean in case of
self -discharge of the accumulator
that will reduce the capacity.
2) Make sure that the holes on the
upper cap are not jammed, or the
plate will be damaged by the vapor
produced by electrolyzing.
3) The electrolyte level should be
10~15mm higher than the plate. Only
distilled water can be filled into the
accumulator. Never fill the accumu鄄
lator with fountain or river water, for
they will do harm to it.
4) Check specific gravity and level of
the electrolyte regularly. Do it every
10~15 days in winter, while every 5~
10 days in summer. Specific gravity
is measured with gravimeter. Table 1
