Lack of maintenance causes many more problems in the long run. Accountants who know nothing of how machines work like to save short term money by deferring maintenance, but that never works in the long term.
I used to repair machines for the semiconductor industry that were very fussy and maintenance intensive, and most customers gave them little attention until they broke down. Some customers maintained them regularly and theirs hardly ever broke down.
It's a lot about how well you know and care for your machine.
