Elevate the table all the way up, then use mineral
spirits to clean any debris and built-up grime from
the elevation leadscrew threads. Add one pump
from a grease gun to the leadscrew grease fitting
shown in Figure 58, then run the table up and
down to distribute the grease. Repeat this process
until the entire leadscrew is well lubricated.
