ASSEMBLY

CAUTION: The spike disks have sharp points. To avoid injury, use extra care when handling the disks and when assembling the aerator.

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.

•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.
