When using the hydraulic jack, do not add partial load or overload, so as to avoid the danger of hydraulic jack damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
Hydraulic jacks use oil as the medium, and the maintenance of the oil and the machine must be done well to avoid blockage or oil leakage, which will affect the use effect. For new or long-established hydraulic jacks, because there is a lot of air in the oil cylinder, when starting to use, the piston rod may have a small jump phenomenon. The hydraulic jack can be reciprocated 2-3 times without load to remove the cavity. air. Hydraulic hydraulic jacks that have been idle for a long time will be hardened due to the long-term inactivity of the seals, which will affect the service life of the hydraulic jacks. Therefore, when the hydraulic jacks are not in use, the hydraulic jacks should be reciprocated with no load for 2-3 months each month.
The high-pressure oil pipe has been tested at 105Mpa (1050Kgf/cm2) when it leaves the factory. However, due to the easy aging of the hose, the user needs to check it frequently, usually six months, and three months for frequent users. During inspection, use 87.5Mpa (875Kgf/cm2) to test the pressure. If there are phenomena such as blasting, bulging, leakage, etc., it cannot be used. The operation should strictly follow the technical specifications, and the user should check and maintain it regularly according to the usage.
