Before carrying out the following work, release
the residual pressure from the hydraulic tank.
For details, see "Testing and adjusting",
Releasing residual pressure from hydraulic tank.

Even if the residual pressure is released from
the hydraulic tank, some hydraulic oil flows out
when the hose is disconnected. Accordingly,
prepare an oil receiving container.
Disconnection
1) Release
the
residual
hydraulic tank. For details, see "Testing and
adjusting", Releasing residual pressure from
hydraulic tank.
2) Hold adapter (1) and push hose joint (2) into
mating adapter (3). (See Fig. 1)
a The adapter can be pushed in about 3.5 mm.
a Do not hold rubber cap portion (4).
3) After hose joint (2) is pushed into adapter (3),
press rubber cap portion (4) against (3) until it
clicks. (See Fig. 2)
4) Hold hose adapter (1) or hose (5) and pull it out.
(See Fig. 3)
a Since some hydraulic oil flows out, prepare
an oil receiving container.
Connection
1) Hold hose adapter (1) or hose (5) and insert it in
mating adapter (3), aligning them with each
other. (See Fig. 4)
a Do not hold rubber cap portion (4).
2) After inserting the hose in the mating adapter
perfectly, pull it back to check its connecting
condition. (See Fig. 5)
a When the hose is pulled back, the rubber cap
portion moves toward the hose about 3.5
mm. This does not indicate abnormality,
however.
