Section 7: Maintenance and Troubleshooting
7.1 Maintenance
7.1.1 Routine Maintenance (approximately every two years)
Under normal operating conditions, the SCE300 actuator does not require maintenance;
however, visual inspection for grease leakage or external visible damage is recommended
every two years. In severe conditions (e.g. frequent operation, high temperatures), replace
all seals that are allowing or may allow leakage of grease or inltration of water.
WARNING
Before performing service or maintenance operations (unless otherwise indicated), ensure
that power is turned off to the unit to avoid injury or damage to equipment.
The following checks are required for optimal actuator performance:
• Make sure that no grease is leaking from the actuator housing
• Check the external parts for possible damage and replace them immediately. If
window glass is broken, the complete cover must be replaced (see Section 8 for
individual item numbers)
• Repaint all areas where paint is missing. In chemically aggressive or saline
environments, remove rust from surfaces and apply a rust preventative
• Check that all nuts and bolts securing the actuator to the valve are tight. If
necessary, re-tighten these fasteners with a torque wrench
• For severe applications or if actuator operation is infrequent, perform maintenance
checks on a more frequent basis than is stipulated by this document
