Method of disconnecting and connecting push-pull type coupler
k
Before performing the following work, loosen the oil filler cap of the hydraulic tank gradually to
release the remaining pressure in the hydraulic tank.
k
Even if the remaining pressure is released from the hydraulic tank, some hydraulic oil flows out
when the hose is disconnected. Accordingly, prepare an oil container.
Type 1
1. Disconnection
1) Hold adapter (1) and push hose joint (2) into
mating adapter (3). (Fig. 1)
a The adapter can be pushed in about 3.5
mm.
a Do not hold rubber cap portion (4).
2) With hose joint (2) pushed into adapter (3),
press rubber cap portion (4) against adapter
(3) until it clicks. (Fig. 2)
3) Hold hose adapter (1) or hose (5) and pull it
out. (Fig. 3)
a Since some hydraulic oil flows out, pre-
pare an oil container.
2. Connection
1) Hold hose adapter (1) or hose (5) and insert
it in mating adapter (3), aligning them with
each other. (Fig. 4)
a Do not hold rubber cap portion (4).
2) After inserting the hose fitting in the adapter
on the other side perfectly, pull it back to
check the connecting condition (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 abnormal-
ity, however.
