Grizzly G3183 instruction manual Head Adjustment

Head Adjustment

Proper adjustment of the head and column is necessary to ensure that mortiser travel is smooth and precise. Two bolts located at the back of the head control the tightness of the head and column. If movement of the head becomes sloppy, tighten the bolts until the travel is smooth and solid. Should the head movement become too difficult, loosen the bolts until movement is satisfactory. Figure 15.

Two setscrews mounted just forward of the bolts ensure that side-to-side movement is minimal. If head displays excess wiggle from side-to-side, loosen the locknuts and tighten the setscrews until movement is eliminated. Tighten the lock- nuts. Figure 16.
