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 hand check whether the leak, the hydraulic oil temperature will often reach 150 degrees F or even higher, can quickly cause severe burns. In addition, the leakage of fluid may have disastrous consequences to touch high speed needle. 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 try to solve the leaking problem only by tightening the nut, only a few cases, liquid leakage due to the nut loosening caused by the excessive tightening will destroy the integrity of the joint, is one of the most 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, don't bring pressure to check the system prior to inspection, please be sure to give the system pressure relief, even if the droplets should do so slowly, the release of pressure can minimize the risk of mechanical components in the hydraulic oil jet burst check when. 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, to ensure that the replacement of the same type of joints, random access to a similar connector replacement, is one of the reasons for the failure.
