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 use. 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.
When the detent valve is
in operation, unnecessary
load is applied to the engine.
Therefore, the engine power
decreases significantly, and
noise and vibration increase
by opening of the relief valve.
