Stow DFG Series manual Floor Brushes, SCRAPE-R-TACH Industrial Floor Coatings Removal System

ASSEMBLY INSTRUCTIONS/OPERATIONS

Wire brushes are available in a number of flat wire sizes and resulting configurations. With continuous use, the flat wire will take a "set" that can limit effectiveness and overall productivity. FIGURE 13. For best results, flat wire brushes should be rotated end for end in the aluminum multi-accessory discs a minimum of once for every one hour of operation. External weight applied to the SURFACE GRINDER will not normally increase productivity rates and only accelerate flat wire wear rates.

Floor Brushes

Eleven inch diameter, silicon carbide impregnated, floor brushes are available in a number of styles and designs for general maintenance and cleaning projects. FIGURE 14. They are especially effective cleaning soiled concrete floors with the addition of water soluble solvents. These types of brushes are directly mounted to the multi-accessory discs with the included 1/2 inch x 2 inch long Grade 5 capscrews. A kidney shaped drive plate is provided on the back side of the brush. This drive plate fits into a recess provided in the multi-accessory disc. FIGURE 15. To maximize bristle service life, it is recommended that the silicon impregnated brushes be rotated between multi-accessory discs a minimum of once for every one hour of operation.

SCRAPE-R-TACH® Industrial Floor Coatings Removal System

This multi-accessory attachment is designed to remove many urethanes, epoxies, paints, mastics and other, similar material accumulations from concrete floor surfaces. FIGURE 16. Each assembly utilizes two tungsten carbide inserts set at a precise angle. The rotating inserts "cut and shave" against the work surface material with a "scraping" action that removes materials with highly productive results. To increase the effectiveness of the inserts, the scraper block design incorporates a Lord® type rubber mount that helps absorb damaging shocks while allowing the inserts to more easily follow local variations in the surface contour. Units are secured to the machine with plastic wedges.
