What is the most important part of plate compactor maintenance?

The exciter mechanism and its oil level are arguably the most important maintenance points, since this is what generates the vibration force that does the actual compaction work, and it fails expensively if run without adequate lubrication. Daily air filter checks are a close second given how much dust these machines are exposed to on UAE sites. Neglecting either leads to reduced compaction performance long before a complete breakdown occurs. Sparkline Group emphasizes both of these checks in the maintenance guidance provided with every compactor it supplies or rents.
