1, use such as empty phenomenon, to relax on the pump body put oil screw and the pump body vertical up head downward air a few times, then tighten put oil screw, you can continue to use.
2, the use of partial load or overload, so as to avoid the danger of ultra high voltage electric jack. In a load, avoid the rapid joint discharge, so as to avoid the occurrence of accidents and damaged parts.
3, the machine oil as medium, we must do a good job in oil and the machine maintenance, to avoid blockage or leakage effect.
4, new or a long set of hydraulic jack, because there are more air cylinder memory, began to use, the piston rod may appear tiny jump phenomenon, super high voltage electric jack no-load reciprocating motion 2-3 times to air out of the cavity. Long term idle electric jack, because seals don't work for a long time caused by hardening seal, thus affecting the service life of the ultra high voltage electric jack, so ultra pressure jack when not in use, the monthly super high voltage electric jack no-load reciprocating motion of 2-3 times.
5, high pressure tubing factory after 105Mpa (1050Kgf/cm2) test. But because the hose is easy to aging, so users need to check frequently, usually for six months, frequent users for three months. Check with 87.5Mpa (875Kgf/cm2) pressure test, such as blasting, uplift, leakage and other phenomena can not be used.
6, the operation should strictly comply with the technical specifications, the user should be regularly inspected and maintained according to the use of the situation.
