00 Index and foreword SEN00056-01 Method of disassembling and connecting push-pull type coupler 1 k Before carrying out the following work, loosen the oil filler cap of the hydraulic tank gradually to release the residual pressure from the hydraulic tank. 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. 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) After hose joint (2) is 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, prepare an oil receiving 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 in the mating adapter perfectly, pull it back to check its 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 abnormality, however.
