DFG-SERIES SURFACE GRINDERS OPERATION AND PARTS MANUAL REV #4 (05/28/09) PAGE 23
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 availa
ble 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-a
ccessory 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 a nd 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
vari
ations in the surface contour. Units are secured
to the machine with plastic wedges.
FIGURE 16
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
