1、不要用手检查是否泄漏，液压油温度经常会达到150°F甚至更高，能迅速造成严重烧伤。此外，用手接触高流速针眼泄漏流体可能带来灾难性的后果。

1, do not use hand to check for leaks. Hydraulic oil temperature often reaches 150 degrees F or even higher, which can cause severe burns quickly. In addition, the leakage of fluid by hand contact with high velocity needle eye may bring disastrous consequences.

2、不要仅通过拧紧螺母就试图解决泄露问题，只有少数情况，液体泄漏时因螺母松动造成的，过度拧紧会破坏接头的完整性，是导致接头泄漏的常见原因之一。

2, not only by tightening the nut to try to solve the leakage problem, only a few cases, liquid leakage caused by the loosening of nuts, excessive tightening will destroy the integrity of the joint, which is one of the common causes of joint leakage.

3、不要带压检查系统，在进行检查之前，请务必给系统泄压，即使液体滴露缓慢也应该这样做，释放压力能最大限度减小机械部件在检查时突发液压油喷射的风险。

3, do not take the pressure inspection system, before the inspection, please make sure to pressure the system, even if the liquid drops slow also should be done, the release of pressure can minimize the risk of hydraulic oil injection of mechanical parts during the inspection.

4、不要更换不同类型的接头来节省时间/成本，确保更换完全相同类型的接头，随意找一个类似的接头替换，是导致故障的原因之一。

4, do not replace the different types of joint to save time / cost, to ensure that the replacement of the same type of joint, at random to find a similar joint replacement, is one of the causes of failure.

5、不要总是怀疑接头，滴油点可能不是泄漏点，液体滴落发生在最低点，虽然液体可能在接头位置滴落，但是实际泄漏点可能在其它部位。

5, do not always doubt the joint, the drop oil point may not be the leak point, the liquid drop occurs at the lowest point, although the liquid may drop in the joint position, but the actual leakage point may be in other parts.

6、不要重复使用O形圈，在重复装配可重复使用的接头时，应该及时更换O形圈，O形圈很容易产生裂纹，从而可能在重复装配时破坏系统的密封性能。

6. Do not repeat the use of O - ring. When repeating reusable joints, the O ring should be replaced in time. The O ring is easy to produce cracks, which may destroy the sealing performance of the system during repeated assembly.

7、在修复泄漏时，不要忘记保护开放的系统，在修复泄漏时，如果将拆卸下来的接头随手扔在地上，然后再重新装上去，会将污染物带入液压系统，会缩短设备的使用寿命。

7, in the repair of leakage, do not forget to protect the open system. When the leakage is repaired, if the disassembled joint is thrown on the ground and then reinstalled, the pollutants will be brought into the hydraulic system and the service life of the equipment will be shortened.

8、更换或者装回接头时，不要忘记清洁连接端，这有助于防止污垢和金属毛刺进入液压系统，这些颗粒物会损坏昂贵的液压部件。

8. Do not forget to clean the connection end when replacing or installing the joint. This helps prevent dirt and metal burrs from entering the hydraulic system. These particles will damage the expensive hydraulic components.

9、无明火，所有明火应远离泄漏点，包括点燃的香烟，用打火机照明和在附近使用焊接。

9. No open fire. All open flames should be away from the leak points, including lighted cigarettes, lighted with lighter and used for welding nearby.

10、不要忽视任何细小的问题，即使轻微的泄漏也可能是更严重液压系统问题的征兆。

10, do not neglect any trivial problems. Even slight leakage may be a sign of more serious hydraulic system problems.
