need replacement.

Figure 31. Leadscrew and ball bearings.
Raise the table up to access the full length of the
handwheel lead screw, as shown in Figure 31.
Use a shop rag and mineral spirits to clean off the
threads of the leadscrew, then brush or wipe on a
thin coat of light machine oil.
Apply a few drops of the same oil to the ball bear-
ings under the handwheel, then move the table up
and down to distribute the lubricant.
