Precautions for using hydraulic lifting jack
1. To ensure the accuracy of the prestress value, the components of the hydraulic system (jacks, oil pumps, control valve lines, pressure gauges, etc.) of the tensioning equipment should be inspected and corrected periodically.
2. The hydraulic lifting jack uses 46 high-quality mineral oil, oil does not contain water, acids and other mixtures, does not decompose and do not thicken at ordinary temperatures. Hydraulic oil should be strictly kept clean, often fine filtration, regular replacement.
3. When prestressing, it should be noted that the tension stroke does not exceed the specified range.
4. When using this hydraulic lifting jack, it should be in accordance with the order form, not be reversed.
5. Hydraulic lifting jack in the beginning of use or during use, such as mixed gas, the hydraulic lifting jack should dry run for 2 minutes, in order to exclude the machine gas.
6. Before Connecting the pump,the oil pipe of hydraulic lifting jack should be checked for laceration, joints are solid, the specifications are appropriate to ensure that in the event of no accidents.
7. Stretched exposed work surface often wipe clean, the rest of the appearance to keep clean, handling should be careful to prevent falls hurt.
8. After work, hydraulic lifting jack cylinder should return in the end, place the room and add dust cover.
9. The hydraulic lifting jack should be based on the actual use of regular maintenance, cleaning the interior and other maintenance work. If found hydraulic lifting jack in the work of oil spills, faults, scratches and other phenomena of the work surface, should stop using and maintenance. Maintenance special wrench, the user if necessary, can be ordered to the factory or make a request when ordering.
10. When working, do not stand at both ends of the component and install protective devices in dangerous areas.
11. No parts of the hydraulic system shall be removed in the case of hydraulic pressure on the Jack.
