 企業從中得不到應有的收益，因此在設備保養上的投入是減了又減，對機器的日常維護也只是維持在低可用水平。然而，頻繁使用機械設備后如果對機器缺少正確的維護保養和矯正措施，肯定會增加機器的突發事故率，不僅使設備的壽命縮短，還會增加企業的生產成本，從而減少經濟收益。維修水平低。機械設備科技含量的提要求設備管理者和維修人員都必需具備相當的綜合知識技能。在機械設備制造技術快速發展的今天，很多維修人員的專業水平并沒有隨著制造技術的提而提，主要體現在：（1）維修者往往只具備單方面的機械、液壓設備維修經驗，缺少與之相關的電子、控制等方面的知識，在維修大型、復雜工程機械時難免會捉襟見肘。（2）某些工程單位由于維修人員數量不夠，維修水平也相對較低，當復雜機械發生故障時找不到癥結所在，必須停機去其他地方找專門的人維修，導致維修時間過長，耽誤了正常的工程進度。（3）企業不視對維修人員的技能培訓，維修人員不熟悉制造度、自動化程度也較的進設備，更談不上所謂的維修和保養了。（4）缺少套維修管理的規章制度。由于維修不當或配件選用不恰當，使得設備在修過之后依然故障頻發，導致這種現象的原因之是維修者水平低下
