求翻译：启动油泵电机，对油缸升压试验，溢流阀调至6Mpa，电接点压力表调至4-5Mpa，然后卸压检查液压系统是否正常，压力表是否灵敏，液压系统接头处是否漏油。是什么意思？

Start the pump motor, the fuel tank boost test, relief valve adjusted to 6Mpa, electric contact pressure gauge adjusted to 4-5Mpa, and then check the hydraulic system is the normal pressure relief, pressure gauge is sensitive to the hydraulic system is leaking joints.

The start oil pump electrical machinery, to the cylinder pressure-rise experiment, the overflow valve transfers to 6Mpa, the electric contact pressure gauge transfers to 4-5Mpa, then release of pressure inspection hydraulic system is whether normal, the pressure gauge is whether keen, hydraulic syst

Start the pump motor, voltage boosting experiments in the fuel tank, adjust relief valve to 6Mpa, electric contact pressure gauge moved to 4-5Mpa, and then check for pressure releasing hydraulic system is normal, pressure gauge is sensitive to joints in hydraulic system leak.
