JRCS thin jack

JRCS thin jack

1、 Purpose:
JRCS series thin jacks have a small volume and can generate greater working capacity, especially when used in narrow spatial locations. They are lightweight, flexible, and have strong lifting capabilities. This product is widely used in enterprises such as power, chemical, steel, bridges, and machinery, and can unleash its infinite power.
2、 Usage method
1. When the oil level of the pump body is insufficient, it is necessary to first add working oil (32 # hydraulic oil or 10 # transformer oil) to the pump before it can work.
2. Estimate the lifting capacity and avoid overloading during use.
3. Choose the point of force for the jack, ensuring that the center of gravity of the lifted object is perpendicular to the top surface of the jack. At the same time, it is necessary to consider whether the ground is soft or hard and whether it is cushioned with tough wood to avoid the risk of tipping during lifting.
4. After lifting the heavy object with a jack, it should be supported firmly with tough wood in a timely manner. It is forbidden to use the jack as a support. If there is no special device, it is forbidden to use multiple jacks at the same time to avoid uneven load and the risk of tipping.
5. When using, first connect the quick connector of the manual pump to the top, then select the position and tighten the oil drain screw on the oil pump to start working. Loosen the oil drain screw and unload the oil cylinder.
6. This series of jacks is engraved with a red warning line, and it is strictly prohibited to use them beyond the warning line.

3、 Precautions
a)、 If there is a phenomenon of empty tapping during use, you can first loosen the oil drain screw on the pump body, then vertically lift the pump body and tap it downwards a few times, and then tighten the oil drain screw. After a strong feeling is felt, you can continue to use it.
b)、 When there is a load, do not remove the quick connector to avoid accidents and damage to the components.
c)、 This machine uses oil as the medium, and it is necessary to maintain the oil and this equipment properly to avoid clogging or oil leakage, which may affect the effectiveness of use.
d)、 New or long-term hydraulic jacks may experience slight piston rod jumps when they are first used due to the presence of air in the cylinder. To remove air from the chamber, the hydraulic jack can be inverted and reciprocated 2-3 times without load. Long term idle hydraulic jacks, due to the hardening of seals caused by prolonged inactivity, affect the service life of hydraulic jacks. Therefore, when hydraulic jacks are not in use, they should be moved back and forth with no load 2-3 times a month.
