Head Tilt & Ram Pinions

The interaction between the cast iron surfaces of these devices (see Figure 57) produces a dry powder that provides an adequate lubrication.

Do not apply any other lubricant that could pro- duce a stiff compound, which may interfere with smooth movement.

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.
