General Notes Regarding the Installation of Flails
1) Because of variance in material thickness and
manufacturing tolerances, the specified number of
spacer washers may not always fit within the narrow
and wide sections. If this occurs, grinding a spacer
washer to reduce its thickness is an option.
FIGURE 20
CAUTION
Exercise caution when grinding a spacer washer
to reduce its thickness. Wear safety eye wear and
other, appropriate safety apparel to minimize the
potential for personal injury.
2) Flails require sufficient free play to allow them to
properly impact the work surface material. If the flails
fit too tight on the drum, inconsistent material removal
and accelerated flail wear will result. The formation of
rust between the flail and spacer washer surfaces will
affect proper free play. Excessive free play can also
accelerate the wear of flails and rods. As a general
rule, flails should be free to rotate by hand after being
installed on the drum. If this is not possible, the flails
should be disassembled and additional free play
provided by reducing the thickness of a spacer
washer.
3) All flails are bi-directional in design with the
exception of the milling flail. That is, there is no
forward or reverse orientation on the drum. Fail
service life can sometimes be extended by reversing
their orientation on the driveshaft. The effect is similar
to rotating tires on an automobile.
4) As the name implies, the tungsten carbide inserts of
the milling flail cut the work surface material with an
action very similar to that of a machine tool cutting
steel. The brittleness of the tungsten carbide insert
requires that it be fully supported to minimize
breakage. This requires a substantial flail body to
provide the necessary support. The resulting
configuration makes the milling flail one directional in
design. This limitation requires the operator to install a
loaded drum on the driveshaft with the tungsten
carbide inserts facing the direction of rotation. FIGURE
21. If the tungsten carbide inserts face opposite to the
direction of rotation, improper milling action and
accelerated flail wear will occur.
FIGURE 21
CAUTION
Before installing the drum on the driveshaft, make
a close, visual inspection of the entire assembly.
Determine that all flails and spacer washers are
properly secured on the rods and that no loose
flail or spacer washer has slipped its position
during assembly. Flails and spacer washers can
fall off the rods during assembly and become
dislodged and unnoticed. When the loaded drum
begins rotating at high speeds, these components
can fly off the drum causing property damage
and/or personal injury.
INSTALLING A LOADED DRUM ON THE
DRIVESHAFT.
Application: All Models.
Tools required:
1 each, 3/4 inch wrench or equivalent.
1 each, torque wrench, 85 ft lbs (115 N.m) capacity
with 3/4 inch socket.
1) If the Floor Planer is powered by an engine,
disconnect the spark plug wire. If powered by an
electric motor, properly disconnect the extension cord
of Floor Planer from the power source.
2) Rotate the height adjustment lever located on the
operator handle counterclockwise to raise the Floor
Planer to its maximum height position above the work
surface.
