Details Steel Wire Joint Sheath:Its joint is equipped with steel wire protection, which can effectively avoid damage caused by excessive bending of the joint oil pipe so that it can be used for a long time. Thickened Plunger:The thickened design of the plunger increases its wearresistance, which can effectively increase the service life of the manual hydraulic pump. Dust Cover: The joints of the jack and hydraulic pump are equipped with a dust cover to prevent dust from entering and damaging them when not in use. High-pressure Oil Pipe:It adopts a high-pressure oil pipe (1m/ 3.3ft) and attaches a quick jointZG3/8'', which makes it convenient and fast for you to use. Anti-slip Ring:The main shaft of the jack is designed with an anti-slip ring so that it has better anti-slip and wear resistance so that you can use it for a long time. Stop Ring:A stop ring is designed between the main shaft and the housing to protect the main shaft from breakage and damage under load. Chrome-plated Main Shaft:The main shaft of the jack has been chrome plated to make it smooth and not easy to jam the cylinder, thus extending its service life. Application It can be used with hydraulic punches, hydraulic cutting machines, hydraulic cylinders, hydraulic tongs, etc. to perform various operations, such as lifting, bending, straightening, shearing, riveting, assembly, disassembly, etc. How to Use 1.Connect the jack to the quick coupler of the hydraulic pump. 2.Turn the pressure relief valve on the hydraulic pump clockwise. 3.Press the handle up and down. 4.Stop working when the stroke is in place. 5.Turn the relief valve counterclockwise.
