The DT/DM machines have had some changes to the base casting. Part of the change was to the front lifting hardware hole size. Previously the machine used 5/8-11 UNC threads for the lifting hardware. The new machines have 3/4-10" UNC threads for the lifting hardware. There will be a transition period for machines built from June to August 2018 while we use up stock of the older base castings. Be prepared to have both 5/8-11 and 3/4-10 size hardware for lifting these machines. ES0246 has been updated to show the new information only.
