The 3-point I inkage
of
S-630 and
S-6300
belongs
to
the Category
1,
which
is
designed for a wide range
of
implements.
Employed
in
S-630 and
S-6300
is
SATOH 'live' hydraulic system
that
makes the hydraul
ic
energy available whenever needed while
the
engine
is
running,
the
hydraulic
pump
being directly mounted on
the
timing gear
case
of
the
engine.
The oil used
is
SAE
#80
gear oil,
the
same
as
that
for
the
transmission
system, and
is
filtered through a 100-mesh oil filter.
Control levers located on
the
right
of
the
operator's seat are for lift
control, position control, flow control (lowering speed control) and lift
lock
of
the
implement.
The
TP
1/4
tap

services
of
the system.
To control
the
implement
in
lifting and lowering, operate
the
hydraulic
control lever.
Moving
the
control lever more
or
less along
the
quadrant
actuates
the
spool valve
in
the
control valve, through which
the
oil from
the
pump
flows into
the
cyl inder, causing
the
implement
to
be
lifted or lowered.
If,
in
some
duty
operations, the implement
is
required
to
limit its lift
