FOREWORD METHOD OF DISASSEMBLING, CONNECTING PUSH-PULL TYPE COUPLER METHOD OF DISASSEMBLING, CONNECTING PUSH-PULL TYPE COUPLER k 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. Type 1 k 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 pressure from the hydrau- lic 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) ! The adapter can be pushed in about 3.5 mm. ! 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) ! 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) ! 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) ! When the hose is pulled back, the rubber cap portion moves toward the hose about 3.5 mm. This does not indicate abnormality, however. 00-8
