The productivity of the product is directly dependent upon the yield and tensile strength of the material being removed. Material thickness has also shown to have a direct effect on overall productivity. For example, the SCRAPE-R-TACH system is a highly productive method for removing thick paint accumulations from factory floors. Production rates 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, stacked bags of cement or weighted drums make excellent weights and can be secured with “bungy” cords. FIGURE 17.

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.

CAUTION

Follow all safety precautions for the safety solvent.

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

2)Remove the cap screw from the unit. Clean the newly exposed areas of the insert and SCRAPE-R-TACH unit with the safety solvent. Clean and inspect the threaded holes found in older units for excess wear. New style SCRAPE-R-TACH units feature a through hole design.

3)Index the insert to expose a new edge. Reinstall the capscrew and apply a torque value that properly seats the insert firmly against the body of the unit.
