Horn of America 1920 Model Airlift Adjustment

This video explains how to adjust the blocks of the Horn of America Model 1920 Airlift to get the mounting board at the correct level for your machine. Large machines are too heavy for these lifts and are not recommended. The lift needs to be in the top position and the machine needs to be off the platform. Break the nuts loose, just enough for the block to slide. Slide the block down to the desired position and tighten the nuts. The adjustment nuts should be 8 mm.
