Hold the adapter (1) and push the hose joint (2) into the mating
adapter (3). The adapter can be pushed in about 3.5 mm. Do not hold
the rubber cap portion (4).
3.
After the hose joint (2) is pushed into the adapter (3), press the rub-

1.
Hold the hose adapter (1) or hose (5) and insert it in the mating
adapter (3), aligning them with each other. Do not hold the rubber
cap portion (4).
2.
After inserting the hose in the mating adapter, pull it back to check
its connecting condition. When the hose is pulled back, the rubber
cap portion moves toward the hose about 3.5 mm. This does not indi-
cate an abnormality.
WARNING!
Before carrying out the following work,
release the residual pressure from the
hydraulic tank. For details, see TESTING
AND ADJUSTING, Releasing residual pres-
sure from hydraulic tank.
WARNING!
Even if the residual pressure is released from
the hydraulic tank, some hydraulic oil flows
out when the hose is disconnected. Accord-
ingly, prepare an oil receiving container.
