On the HW110LC, the cast iron table is cabinet mounted. This means the main part of the cast iron table is bolted directly to the cabinet using 4 bolts (Cap screw size: M10-1.5 x 25mm). 

However, there are also 2 set screws located next to the bolts (hidden by the flat washer). These set screws are located in diagonal corners (front left & rear right), which will prevent you from making any adjustments to the cast iron table until they are COMPLETELY removed. 

The purpose of the set screw is to prevent the tables from moving/shifting when being shipped. If any alignment is needed, then these set screws are removed and discarded as they will no longer align with the original holes. Below is a video demonstrating this:
