Provisions must be made to prevent the HANDWHEEL RETAINING NUT FROM BACKING OFF whenever a chain wheel is installed. To insure safe operations, Roto Hammer recommends that thorough inspection of all chain operated valves be performed as a routine part of the user’s Safety/Maintenance Schedule. Set screws and other threaded fasteners MUST be secure and tight.
In addition, it is strongly recommended that an appropriately sized Roto Hammer RCK Safety Cable Kit (optional) be installed on every overhead chain wheel operated valve
