集电器：至少每季度检查一次。重点检查紧固件有无松动、移位及塑料件和流动件磨损情况，检查弹簧拉力（集电器电刷与导轨的接触压力应保持一定压力（见下表）。发现题目及时处理。
Collector: at least quarterly check once a. Focus on examination of the fastener looseness, displacement and plastic parts and flow parts wear, check the spring tension (contact pressure collector brush and guide should maintain certain pressure (see table below). Find the problem timely treatment.
  日常检查：重点检查轨道的平直度有无显著偏差（大于20mm）、错位，绝缘保护件有无脱落、断裂、破损，不锈钢“v"型槽有无翘起；轨道上有无异物及导电粉尘等。必要时应检测其绝缘电阻是否符合要求（相间绝缘电阻应≥5MΩ）。
Daily check: focus on examination of rail straightness has no significant deviation (more than 20mm), dislocation, insulation protection piece with no loss, damage, fracture, stainless steel "V" type groove is no tilt; orbital foreign bodies and conductive dust etc.. When necessary, to detect the insulation resistance is to meet the requirements (interphase insulation resistance should be greater than or equal to 5M.).
  连接件：至少每年检查一次。重点检查紧固螺栓、焊缝及支撑件是否松动、锈蚀、移位等，发现题目，及时处理。
Connections: at least once a year to check. Focus on examination of the fastening bolts, welds and support is loose, corrosion, shift, found the problem, timely treatment.
