First, use
JRCS series thin jack jack, smaller, and have a greater ability to work, particularly in the spatial location of the narrow places, and has a light and flexible, the top edge and large functions, the product is widely used in electric power, chemical, steel, bridges, machinery and other enterprises, and to play its infinite power.
Second, the use
1, the ministries must be checked before use is normal.
2 should be used in strict compliance with the provisions of the main parameters, should not high overload, or when the lifting height or lifting tonnage in excess of requirements, the tank top of a serious oil spill.
3, such as manual hydraulic oil pump body is insufficient, need to add the first pump should be sufficiently filtered by N33 # hydraulic oil to work.
4, the electric pump electric pump to use refer to the instructions.
5, the weight center of gravity to choose moderate, reasonable choice of Jack the focal point, to pad the bottom level, taking into account the hard and soft ground conditions, whether the timber liner tough, place is stable, so as not to load subsidence or tilt.
6, the jack lifting heavy objects, it should be timely and firmly supports the weight support to prohibit the use of the jack as the support. For a long time to support weight please use the CLL self-locking jack.
7, a few jacks for lifting the same time, in addition to jack should be placed correctly, the diverter valve should be used more than the top, and each load should be balanced jack to keep the lifting speed synchronization. Must also consider the weight due to uneven ground may subside, and prevent lifting, have tilted dangerous.
8, using the manual hydraulic pump when the first quick connector and the top butt, and then choose the right location, will be put on the oil pump screws tightened, you can work. Purports to decrease piston rod, the manual hand pump counterclockwise slightly loosen the wheel, cylinder unloading, the piston rod is decreased. Otherwise, the excessive rate of decline would be dangerous.
9, the structure of the jack spring system reset, after lifting, you can quickly take out, but not with the connection of the hose to pull the jack.
10, due to smaller travel lifting jack, users do not exceed the rated travel time to avoid damage to the jack.
11, using the jack should be avoided during severe vibration.
12, not suitable in a pH, corrosive gases used in the workplace.
13, the user should be based on the use of regular inspection and maintenance
