Refer to
Figure 5
for Driven Element Housing and Return EST assembly.
Mount the Element Support Plate and Return Plate to the boom first, leave the bolts loose
enough to allow leveling adjustments.
Level the plates to the boom first, so that the eye of the EZ eye is on the top side of the
boom. Then attach the EST extensions once the plates are secured. Tighten boom saddle
bolts to 20ftlbs (27.09Nm) Tighten the EST exsention saddle bolts to 7 ftlbs (9.5Nm) This will
prevent the fiberglass from cracking or breaking.
