Lubrication

There are four points on the ironworker that require at least monthly lubrication: 1) The beam pivot shaft, 2) the shearing hold-down adjustment rod, 3) the angle iron hold-down screws, and 4) the shearing support frame leadscrew and bev- eled gears.

Before lubrication, wipe debris and built-up grime from all threaded parts and gearing. Clean away any remaining material with a solvent or min- eral spirits product such as the cleaner/degreaser from Grizzly shown in Figure 9 on Page 15.

Beam Pivot Shaft

Use a grease gun to add 1–2 pumps of multi-pur- pose automotive-grade grease to the beam pivot shaft grease fitting on the rear of the machine (see Figure 49).
