of up to several hundred square feet per hour can be realized. However, many thin film ( ie: 5 mill thickness and thinner) urethane coatings present a much more difficult removal problem. Since removal rates are also directly affected by applied down force, up to 300 lbs of external weight can be applied to the SURFACE GRINDER to increase productivity. Cement blocks or stacked bags of cement make excellent weights and can be secured with "bungy" cords or other means with the provided holes in the top cover. FIGURE 17.

Each insert provides 8 scraping edges. As an edge become dull and worn, the insert can be turned and reinstalled to expose a new, sharp edge. FIGURE

18.When all 4 edges of one side become worn and dull, the insert can be turned over to expose an additional 4 edges.

Many materials such as adhesives, rubber deposits and mastics have the tendency to extrude or smear rather than shear from the concrete floor material. The occurrence is also aggravated by higher ambient temperatures. This problem can be significantly reduced with the addition of various amounts of water or a water saturated, fine sand combination placed on the floor. The use of the Safety and Dust Shield Assembly with the SURFACE GRINDER is highly recommended to contain the water/sand slurry mixture from damaging surrounding walls and other vertical surfaces.

To index the tungsten carbide insert, proceed as follows:

Tools required:

1 each, 5/32 Allen wrench.

1)Clean the SCRAPE-R-TACH unit with a suitable safety solvent to remove excess material build- up. Remove as much foreign material from the female hexagon socket area of the capscrew. This will allow the wrench to make full contact and maximize the torque transfer to the cap screw.
