to
the
side and
loosen
them
slowly
to
gradually release
the

not
release
pressure:
•
When
the
attachment is
not
in
the
rest position.
•
During operation
of
the
attachment.

coupling
(a)
(a')
by
pulling
the
knob
(1)
outward first and then upward.
Release
the

hydraulic lines
to
ports
(a)
or
(a')
and
(b)
or
(b').
When fitted with a
hydraulic
breaker:
a.
Connect the return circuit to port
(b)
or
(b') and the supply
circuit to port
(a)
or
(a
'
).
b.
Turn
on
the
flow selector
switch and
select "one-way".
Refer to page
58,
"Flow Selector
Switch."
Some
attachments may have a case
drain, which needs to be connected to
the
small
