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 (0.14 in).
Do not hold the rubber cap portion (4).

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 (0.14 in). This
does not indicate an abnormality.
WARNING!
Before carrying out the following work, release the
residual pressure from the hydraulic tank. For
details, see
WORK EQUIPMENT: Releasing
Residual Pressure in Hydraulic Circuit i
n the
Testing and Adjusting section.
WARNING!
Even if the residual pressure is released from the
hydraulic tank, some hydraulic oil flows out when
the hose is disconnected. Prepare a container to
receive the oil.
