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 are often up to 150 ° F or higher, can cause serious burns quickly. In addition, the use of hand contact with high flow velocity conifer leakage fluid may have 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, don't just by tighten nut has tried to solve the problem of leaking, only a few cases, liquid leakage caused by loose nut, too tight will destroy the integrity of the joint is one of the common cause of the 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, don't bring pressure inspection system, before the check, please give the system pressure, even if liquid did slow should do the same, can release pressure minimizing mechanical parts in the test when the risk of sudden hydraulic oil injection. 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 different types of joints to save time/cost, make sure that the same type of joint is replaced, and find a similar replacement for the joint, which is one of the causes of failure.
