CAUTION: The spike disks have sharp
points. To avoid injury, use extra care when
handling the disks and when assembling
the aerator.
• Insert the end of the axle through one of the end
plates. See figure 4.
• Assemble onto the axle, in order, a short spacer, a
spike disk and a spring. See figure 4.
NOTE: All spike disks should face the same direction.
• Next, starting with a spike disk, assemble seven spike
disks and six long spacers onto the axle. See figure 4.
• Finally, assemble a spring, a spike disk and a short
spacer onto the axle. Push the end of the axle through
the second end plate. See figure 4.
TOOLS REQUIRED FOR ASSEMBLY
(2) 1/2" open or boxed end wrench
(1) Hammer
Lay out and identify all parts and hardware as shown in
Carton Contents and Hardware Pack illustrations.
• Assemble the two frame angles (one with the bend
up and the other with the bend down) to the two end
plates using eight 5/16" x 3/4" hex bolts and eight
5/16" nylock nuts. Make sure that the frame is squared
up, and then
tighten. See figure 1.
• Using a hammer, drive a spring pin into a hole in the
axle until the pin just slightly extends through the other
side of the axle. Next, assemble a flanged bearing
onto the axle as shown. See figure 2.
