It is recommended to inspect and clean the twistlock on a regular basis, this includes greasing the movable parts and checking the function of  the mechanism and spring action.

Twistlocks with damaged cones of bodies are to be scrapped. Other damaged elements (Wire handle, bolts,..) can be replaced as described in the repair instruction.


By removing the bolts and nuts, the body halves can be separated. Cone assembly, spring and wire handle can be removed.
