IMPORTANT
Put the detent valve operating
lever into the neutral position
when the hydraulic implement
is not in use. If the detent valve
is kept in the operating position
for an extended period of time,
the relief valve is kept open and
the temperature of the hydrau-
lic fluid rises, leading to dam-
age of various hydraulic parts,
such as the oil seals and O-
rings.
When the detent valve is in
operation, unnecessary load is
applied to the engine. Therefore,
the engine power decreases
significantly, and noise and vi-
bration by opening of the relief
valve increase.
It is hard to start the engine
while the detent valve is in
operation. This is especially
true in winter and exhaust gas
increases even after the engine
is started.

This tractor is equipped with the re-
mote control valve of the double act-
ing type. However, this valve can also
be used in the single acting type hy-
draulic cylinder.
1. Connect one end of the hydraulic
port to the single acting cylinder as
shown in the figure. The hydraulic
pressure is properly supplied to the
cylinder. However, when the hy-
draulic pressure is released, the
cylinder is contracted only if there
is outer force, such as potential
energy.

2. To contract the cylinder, operate the
lever to the opposite position of the
expansion. Then, the hydraulic fluid
is supplied from the hydraulic pump
to the hydraulic port which is not
connected, and the pressure rises
as the port is blocked. However, this
pressure is released as the relief
valve opens.
