(1) Quick Coupler
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 hydraulic
fluid rises, leading to damage
of various hydraulic parts, such
as the oil seals and O-rings.
