The battery
with
the
diesel engine
hasn't
been charged before delivery,
it
should be
first
charged as
the
battery's
requirement before used.
When
the
diesel engine is
working,
the
amount
of
the
charging current should often be noticed.
When
the
nee-
dle
of
the
ammeter
is reaching
to
zero, it
shows
that
the
battery has been fully
sharged and
the
charging circuit can be
switched
off.

2 Silicon rectified dynamo
JF series silicon rectified dynamo is adopted in
the
diesel
engine,
there are many
types
of
JFl312YE,JF2312YE,JF2512YE ,JFZ1512YE, BJFW23B
,and
etc.
The diesel engine
for
tractor adopts JF1312YE
type
of
12v,
the
oter
engines usually a-
dopt
dynamo
of
24V;the
engine
with
vacuum
pump
adopts BJFW24B
type,
six cylin-
ders engine
for
truck
adopts JF2512YE type.'

3 Voltage regulator
The use
of
this voltage regulator is
to
keep
the
voltage
at
the
range
of
13.5
-14.
5V
or
27
-29V
respectively
when
the
speed
of
the
14V
or
28V generator changed. These
two
types
of
generators adopt
FTIII,
FT211
AND FT226 voltage regulators respec-
tively,
the
FT226
type
regulator can be connected
to
a charging indicator.
When
the
FTIII
type
and
FT211
type
regulators are
used,
the
key
swich
should
be
turned
off
as soon as
the
engine stops in case
the
battery discharge
to
the
magnetic
coil
and
make
the
battery insufficient,this will influence
the
next
starting.
The
regulator is a precise instrument and
not
be
dismatled and
regulated
at
will,
if it
is necessary
to
be adjusted,
it
should be done
at
specicl equipment.

4 Starting
motor
The starting
motor
is full closed direct current .series excitation
motor,
the
engine
of
12V s'yIStem
adopts
OD1518E.OD154.0154C
types.and
the~engine
of
24V
system
a-
dopts
QSZ637E
type starting
m~tor.
In
oreder
to
improve
the
starting capacity,
QDl54C
type
motor
adopts 9
teeth,and
the
OD154
adopts
11
teeth.
