when assembling and dissembling, as this could cause a deterioration of the mechanical
parts.
Maintenance of the Portable Valve Actuators should be carried out by people who have
been trained by modec.
Our “After Sales Service” department are ready to help in this respect.
Systematically disconnect the actuator from the power feed (battery pack or mains)
before carrying out any procedure that involves replacing, adjusting, servicing or
dissembling the actuator or any of its parts.
Every time maintenance is carried out, test the actuator afterwards to check it is
working correctly.
Only use approved replacement parts and follow the manufacturer’s advice with regard to
lubrication and waterproofing.
