1、保证油、水、空气有充足的供应量。如果这些能源供应不足，就会导致起重机难以发动、润滑不良、功率下降、磨损严重、不能正常运转，缩短使用寿命。
1, ensure the oil, water, air supply sufficient. If the energy supply is insufficient, will cause the crane is difficult to launch, poor lubrication, power down, wear serious, can not operate normally, shorten the service life.
2、对起重机容易出现问题的部位，做好日常的安全检查工作。由于起重设备在使用过程中会受到不同力度的震动冲击，紧固部位的螺栓、螺母就会出现松动，所以要经常检查，预防因松动而损坏机体的故障。
2, the crane is prone to problems of the area, do a good job in safety inspection work everyday. Because the lifting equipment will be affected by different degree in the process of using vibration impact, will bolt, nut fastening parts of loose, so always check, prevent the body from being damaged due to the fault of loose.
3、油、水、气和机体要保持干净。如果燃油不纯净，就会发生漏油、滴油、甚至油路堵塞等现象；空气和水的纯度不高，则会影响发动机散热能力，磨损机体；机体表面不打扫干净的话，会腐蚀机体，带来不必要的损失。
3, oil, water, gas and the body to keep clean. If the fuel is not pure, there will be leakage, drop of oil, even oil plug phenomenon; the purity of water and air is not high, it will affect the heat capacity, engine wear body; the body surface is not clean, will erode the body, cause unnecessary losses.
4、掌握正确使用发动机的方法。在使用前、使用中、使用后都应该运用正确的操作方法，要仔细观察、常检查，以便及时发现问题并解决，使发动机保持正
4, grasp the correct way to use the engine. Prior to use, after use, should use the correct method of operation, careful observation, inspection, in order to discover problems and solve, to keep the engine is
常的运转。
Often running.
5、发动机在使用前必须严格按照规定进行磨合，这不仅是使用的前提，还是延长使用寿命的基础。
5, the engine must be run in strict accordance with the provisions before use, it is not only the use of the premise, or extend the basis for life.
6、要及时检查调整与发动机相关的各个零部件，使起重机发动机始终保持良好的状态运转。
6, to the timely check and adjust the various components associated with the engine, make the crane keep the engine running condition good.
