This product is equipped with two
double acting valves [Spring return
(2port) + Detent (2port)] to supply
hydraulic power to the outside. Use
them properly according to an imple-
ment'sspecications.
• For the self-return type double act-
ing lever, it returns to its neutral
positiontoblock thehydraulicuid

pulled or pushed continuously for
operation which is suitable for an
implement with a short operating
time, such as a hydraulic cylinder.
Put the detent valve operating
lever into the neutral position
when the hydraulic implement
is not in us e. If the detent
valve is kept in the operating
position for an extended pe-
riod of time, the relief valve is
kept open and the temperature
of the hydraulic fluid rises,
leading to damage of various
hydraulic parts, such as the
oil seals and O-rings.
W h en the d e ten t val v e is
in operation, unne cessary
load is applied to the engine.
Therefore, the engine power
decreases significantly, and
noise and vibration increase
by opening of the relief valve.

IMPORTANT
It is hard to start the engine
while the detent valve is in op-
eration. This is especially true
in winter and exhaust gas in-
creases even after the engine
is started.
The detent valve can be ap-
plied as an option.
