4.检查炭刷(图 30

马达使用炭刷这种消耗品。因过度磨损的炭刷会 导致马达发生故障,因此,当炭刷磨损或接近 磨损极限时,请换上新的炭刷。此外,请始 终保持炭刷的清洁,并确保它能在炭刷盒里自由 滑动。

换上新的炭刷时,请一定使用日立牌炭刷(代码 号:999058)。

5.更换炭刷

如图 32 所示,先取下刷帽,然后用平头螺丝刀等 钩住炭刷的突起部分,取出炭刷。

安装炭刷时,选择方向,使炭刷钉对准炭刷管外 面的连接部分。如图 33 所示,用手指将其推入。 最后安装刷帽。

注意

务请将炭刷钉插入炭刷管外面的连接部分。(可插 入附带的两个炭刷钉中的任何一个)。

须特别注意,因为操作的任何差错均会导致炭刷钉 变形,并且可能在很早的阶段就导致马达发生故 障。

6.清洁外部
