1-1 any work, safety is first hollow cylinder large tonnage, particularly in jack at high pressure, large tonnage, where applicable, but also to pay attention to safety. 1-2 into the jack of all people using the site should be "a ring pumps, jacks at both ends of clearance." On the one hand to avoid wounding slide wire tensioning, on the other hand to avoid misuse jack parts flying wounding. 1-3 "pump opened, the Secretary shall not leave the pump." Pay attention to the fuel gauge value. When the return, if the fuel gauge ultra rapid boost type large tonnage cylinders, should immediately stop the pump. Other 3-1 before connecting tubing must be cleaned tubing hydraulic cylinder large tonnage, particularly nozzle section. 3-2 tensioning jack before use should be no-load operation 3-5 times, excluding air cavity. 3-3 tensioning jack operation, the load should be smooth, slow unloading should avoid slippery silk.
