Before and after the demolition of the demolition, to prevent fuel tank parts being contaminated by dirt or impurities, should be operated in a clean environment and clean all parts of the application after the demolition of plastic sheeting cover, do not use cotton or other Work cloth. Then also on a detailed examination of these parts, the maintenance repair, replacement must be replaced, not just live with. Assembly Notes (1) cylinder before assembly, parts and components required to respond externally threaded cylinder cleaning and inspection role with earrings lever confirm without any problems. (2) for each cylinder in the sealing device, to be installed correctly, elastic fit, too loose or too tight will affect the sealing effect, so that the fuel tank leak oil spills and other phenomena occur, loss of seal. Prevent air pollution caused by the invasion of the hydraulic cylinder inside to prevent air intrusion should note the following points: 1, according to the random after repairs and oil changes for excluding air from the system to normal operation. 2, the oil pump drive shaft seal should well to pay attention to where the seals should be replaced using the "lips" genuine seal, can not use the "single-lip" seal instead of double-acting hydraulic cylinder oil plug design, because the "single lip" seal only unidirectional seal oil, does not have the function of sealing gas. Hydraulic pump consecutive "cavitation" noise, such as elevated oil tank automatic failure, hydraulic pump repair process through inquiry, discovery is the hydraulic pump drive shaft seal misuse "single lip" seal due. Single-acting hollow plunger hydraulic cylinders, hydraulic power Lu (certified), provided by the Texas Lu Suizhou cylinder of hydraulic equipment plant.
