ASSEMBLY INSTRUCTIONS/OPERATIONS
Suggested Applications:
1)Removing synthetic coatings, thermoplastic and cold plastic marking and lines from concrete and asphaltic surfaces.
COST 10 PRODUCTIVITY 7
SERVICE LIFE 7. Milling flails are designed to remove
avariety of traffic line materials from concrete and asphaltic type surfaces. With proper techniques, minimal amounts of parent work surface material will also be removed during the planing process. Milling flails are expensive. To realize maximum service life, milling flails should not be utilized for the direct removal of concrete and asphaltic work surface materials. Such use will drastically reduce their service life and substantially increase project costs.
SPACER WASHERS.
Spacer washers are stamped from high carbon, alloy steel that is heat treated for additional service life. FIGURE 6.

The Function of Spacer Washers
1)Reduce the number of flails required to be mounted on the flail drum, thus reducing purchase and operational costs.
2)Arrange the flails in a sequence or pattern that minimizes "blind" or "open" spots created by the additional support plates of the two section flail drum. Always insert at least one spacer washer between two
(2)consecutive flails. The exception to this rule is a configuration where its design does not require the use of spacer washers. A flail drum set up with only star, beam or pentagonal flails and no spacer washers will not penetrate the work surface at satisfactory rates. Typical configurations minimize the hammering or impact action of the flails. However, this can also be useful when removing traffic lines.
3)Allow the flails to be arranged on the one section flail drum in configurations of specific widths for many job applications. An example would be the use of pentagonal flails to groove a concrete floor. The spacer washers are used to position the pentagonal flails at the desired width. FIGURE 7.
Variances in material thickness and manufacturing processes can affect the final thickness of both flails and spacer washers. Because of this occurrence, trial and error is important for assembling flails and spacer washers on a flail drum. By mixing and matching flails and spacer washers of specific thicknesses, the required number of components can be assembled on a flail drum in a minimum amount of time.
DANGER
USE ONLY FACTORY SUPPLIED SPACER WASHERS ON THE FLAIL DRUM. OTHER WASHER TYPES AND/OR CONFIGURATIONS CAN PRODUCE ABNORMAL WEAR AND ELONGATION, RESULTING IN COMPLETE SEPARATION FROM THE FLAIL DRUM. SPACER WASHER SEPARATION CAN RESULT IN PROPERTY LOSS AND/OR PERSONAL INJURY.
FIGURE 7
FLAIL DRUM RODS
Flail drum rods are manufactured from 1/2 inch diameter alloy steel. They are heat treated in a two step process that yields a surface hardness that resists wear and extends service life.
Drum rod service life is difficult to predict because of the large number of flail configurations and work surface materials. Normal wear should be uniform about the rod circumference. FIGURE 8.
