How to use:
1. If the oil volume of the pump body is insufficient, you need to add working oil (32# hydraulic oil or 46# hydraulic oil) to the pump before it can work.
2. Estimate the lifting weight and avoid overloading.
3. Select the jack's force point to ensure that the center of gravity of the lifting object is perpendicular to the top surface of the jack. At the same time, you must consider whether the ground is soft and hard and whether it is padded with tough wood to avoid the danger of tipping during lifting.
4. After the jack lifts the heavy object, it should be supported firmly with tough wood in time. It is forbidden to use the jack as a support. If there is no special device, it is forbidden to use several jacks at the same time to avoid uneven load and the danger of tipping.
5. When using, first connect the quick connector of the manual pump to the top, then select a good position, tighten the drain screw on the oil pump, and it can work. Loosen the drain screw and unload the oil cylinder.
Notes:
a) If the pump is empty during use, loosen the drain screw on the pump body first, then vertically lift the pump body and empty it for a few times, then tighten the drain screw, and continue to use it after you feel the force.
b) When there is a load, do not remove the quick connector to avoid accidents and damage to the machine parts.
c) This machine uses oil as the medium, and the oil and the machine must be well maintained to avoid clogging or oil leakage, which will affect the use effect.
d) For new or long-standing hydraulic jacks, there is a lot of air in the cylinder, and the piston rod may have a slight jump when it is used at the beginning. The hydraulic jack can be inverted and reciprocated 2-3 times without load to remove the air in the cavity. For jacks that have been idle for a long time, the seals will harden due to long-term non-operation, which will affect the service life of the hydraulic jack. Therefore, when the hydraulic jack is not in use, the hydraulic jack should be reciprocated 2-3 times without load every month.
