-- As all the securing bolts are applied with bolt thread sealant, they normally will not loosen up and a visual
inspection would be sufcient.
-- Any bolt that is found loose, broken or defective must be replaced.
-- Apply a little amount of thread sealant on thread and surface of all bolts.
-- Check the slewing reducer cap, pipelines, and bearing housings for leaks.
