This machine is equipped with two
double-acting valves (self-return
type) which can supply hydraulic
pressure to exterior devices. Utilize
them properly according to imple-
ment specifications.
• For the self-return type double ac-
ting lever, it returns to its neutral
position to block the hydraulic fluid
when it is pushed/pulled and then
released. Therefore, this type of
double acting valve lever should be

• 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 temperatu-
re 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. The-
refore, the engine power de-
creases significantly, and noi-
se and vibration increases by
the opening of the relief valve.
• 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.
