Screws Check that screws and bolts are securely fastened. Re-tighten them, if loose. For repair or parts replacement, contact M-System or our representatives. ■ LUBRICATION There is no need of oiling the Mini-Top electronic actuator in normal operating conditions. ■ REGULAR TEST RUNNING If the valve is not frequently operated, run a test operation regularly (once a week, for example) to ensure that the actuator operates normally.
