Abstract：Surgical microscopy plays an important role in fine surgery in hospitals. Zeiss Pentero microscopy in Germany
provides excellent optical quality and flexible operation for neurosurgery and ophthalmic surgery. Three typical faults of
Pentero microscope were summarized in this paper. The first one was the failure of automatic adjustment and balance caused
by the damage of step motor. The second one was the black screen caused by the damage of UPS part of power module. The
third one was the failure of inversion caused by the rupture of tension spring. The stepwise analysis method and substitution
method were used to solve these faults in the maintenance process. The date of this type of machine was summarized. The
direction and method of regular maintenance can provide references for peers.
