Release the residual pressure from the hydraulic tank by loosening
the oil filler cap. 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).
2.
After the hose joint (2) is pushed into the adapter (3), press the
rubber cap portion (4) against the adapter until it clicks.
3.
Hold the hose adapter (1) or hose (5) and pull it out. Since some
hydraulic oil flows out, prepare an oil receiving container.
CONNECTION

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
indicate an abnormality.
WARNING!
Before carrying out the following work,
release the residual pressure from the
hydraulic tank by loosening the oil filler cap.
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.
