3 Maintenance, service and troubleshooting 3.1 Maintenance The QT2500 is in principle maintenance-free; all bearings and gears are lifetime lubricated and components are designed to last throughout the actuator’s lifetime. It is however recommended that the actuator is inspected regularly to reveal any damages caused by mechanical impact, corrosion, etc. The top cover gasket and manual operation shaft seal should be lubricated with suitable lubricants if they appear to be dry.
