Features:
1. Small size, light weight, easy to use, but high working pressure.
2. Single-stage pump station: Simple structure, capable of achieving higher working pressure.
3. Dual-stage pump station: At low pressure, the high-pressure and low-pressure pumps supply oil simultaneously, resulting in a higher output flow rate. At high pressure, the low-pressure pump automatically returns oil without load through a relief valve, reducing power consumption.
4. Pressure retention function: When there is no leakage in the external oil circuit, stop the pump and maintain pressure for 5 minutes, with the rated pressure not dropping by more than 5 Mpa.
Usage Instructions:
1. Before use, it is necessary to check whether all components are functioning properly.
2. When using it, strictly follow the regulations in the main parameters. Avoid excessive height and overload. Otherwise, when the lifting height or lifting tonnage exceeds the specified limits, serious oil leakage may occur at the top of the cylinder.
3. If the oil level in the manual pump is insufficient, it must be filled with properly filtered N33# hydraulic oil before it can operate.
4. For the electric pump, please refer to the electric pump user manual.
5. The center of gravity of the heavy object should be chosen appropriately. Select the jack point carefully, ensure the bottom surface is level, and consider the hardness of the ground. Determine whether to use tough wood padding and whether the placement is stable to prevent sinking or tilting under the load.
6. After the jack lifts the load, it must be firmly supported with a support device promptly; the jack shall not be used as a support.
7. If several jacks are used for lifting simultaneously, in addition to proper placement of the jacks, multiple flow dividers should be utilized, and the load on each jack must be balanced to ensure uniform lifting speed. Additionally, the possibility of ground settlement due to uneven weight must be considered to prevent the lifted object from tilting and causing danger.
8. When using it, first connect the quick connector of the manual pump to the top, then select the appropriate position, tighten the oil drain screw on the pump, and it will start working. To allow the piston rod to descend, slightly loosen the handwheel of the manual pump by rotating it counterclockwise, thereby relieving the load in the cylinder, and the piston rod will gradually move down. Otherwise, if the descent speed is too fast, it may be dangerous.
9. This jack features a spring reset mechanism. After lifting is completed, it can be removed quickly, but the connecting hose should not be used to pull the jack.
10. Since the lifting range of the jack is relatively small, users must never exceed the rated range during use to prevent damage to the jack.
1.1 During use, avoid severe vibration of the jack.
1.2: Not suitable for use in workplaces with acids, alkalis, or corrosive gases.
1.3, users should regularly inspect and maintain them based on usage.

Purpose:
1. Compatible with oil cylinders or specialized machinery, capable of performing tasks such as lifting, bending, straightening, extruding, shearing, riveting, disassembly, and press fitting.
2. The device serves as a hydraulic power source in certain mechanical equipment.
3. Pressure testing pump station for various high-pressure hydraulic components, high-pressure containers, and high-pressure hosesOr install a manual pump.
Notes:
1. If the pump operates with no flow, first loosen the oil discharge screw on the pump body, lift the pump body vertically and press it down a few times to create flow, then tighten the oil discharge screw, and the pump can be used again.
2. When in use, do not apply additional loads or exceed the capacity, to prevent danger due to damage by the jack. When under load, never remove the quick-connect fitting, to avoid accidents and damage to components.
3. This machine uses oil as a medium; proper maintenance of the oil and the machine itself is necessary to prevent blockage or oil leakage, which could affect its performance.
4. For new or long-unused hydraulic jacks, due to the presence of excess air in the cylinder, the piston rod may experience slight jumps when first used. The jack can be moved back and forth without load 2–3 times to remove the air from the chamber. Jacks that have been unused for a long time may suffer from seal hardening caused by the lack of operation of the seals, which in turn affects their service life. Therefore, when not in use, the jack should be moved back and forth without load 2–3 times per month.
5. The high-pressure oil pipe undergoes a test at 105 Mpa (1050 Kgf/cm²) when leaving the factory. However, due to the tendency of rubber pipes to age, users must check them regularly—typically every six months, or three months for frequent users. During inspection, a pressure test at 87.5 Mpa (875 Kgf/cm²) is performed; if there are any bursts, protrusions, or leaks, the pipe cannot be used.
6. Strict technical specifications must be followed during operation, and users should conduct regular inspections and maintenance based on usage conditions.
7. If the oil level in the pump is insufficient, work oil (10# engine oil) must be added to the pump before it can operate.
8. Determine the center of gravity of the load, select the jacking point, and also consider whether the ground is soft or hard; use tough wood as padding to prevent the risk of tipping during lifting.
9. After the jack lifts the heavy object, it must be firmly supported with sturdy wood promptly. The use of the jack as a support is prohibited, and multiple jacks should not be used simultaneously to avoid uneven load distribution and the risk of collapse.
10. When using it, first connect the quick connector of the manual pump to the top, then select the appropriate position, tighten the oil drain screw on the oil pump, and it will start working. Loosen the oil drain screw to relieve pressure from the cylinder.
