the indicator light of the electromagnetic coil will be bright. If it is not clear that the
coil is not energized, check the switch or circuit problem;
2、如果⑧ 电磁线圈指示灯会亮，则不会下降，需把⑧ 电磁线圈折下来，按开关 DN 键的
同时，用螺丝刀或者其它铁的工具插入电磁线圈孔里，检查是否有吸力或磁性，如果没有吸
力和磁性，证明⑧电磁线圈内部短路，更换⑧电磁线圈即可；
2, if today the electromagnetic coil will bright lights, do not drop, the
electromagnetic coil was broken off, press the switch DN key at the same time, use
a screwdriver or other iron tool into the electromagnetic coil in the hole, check
whether there is a suction or magnetic, if there is no suction and magnetic, that was
internal short circuit, the electromagnetic coil electromagnetic coil can change
today;
3、如果⑧电磁线圈指示灯亮，产生吸力和磁性，而不会下降，需要把⑨常闭电磁阀拆下来，
用汽油或者柴油清洗阀孔和滤网，可能是阀孔堵塞，清洗后装上再试或检查
○

节流阀是否
完全关闭，把节流阀螺丝杆调松开一些，节流阀越松回油流量越大，如果还不会下降或回油，
则需更换⑨常闭电磁阀。
以上方法都用过，还无法使用的，可能是油管堵塞不通，或者是液压缸有问题和液压动力
单元型号选择错误。
3, if the electromagnetic coil end indicator, creating suction and magnetic, and
won't fall, need to put the pet-name ruby normally closed electromagnetic valves
are removed, clean with gasoline or diesel valve holes and mesh, may be a valve oil
plug, mount try again after cleaning or inspection
