Five Section Boom Operation
L. Assemble top rear wear pads with the cam plates to the top of the 5
th
section. The
wear pad on each side of the top/rear of the boom can be adjusted over a range of
3/16 inch (4.8mm) by rotating, end for end, the wear pad and plate or the wear pads
and plate independently. This is possible because the holes in these parts are offset
from the center. The holes are .06 inch (1.5mm) off center in the plate and .03 inch
(.8mm) off center in the wear pad. Various combinations of rotation of these parts
allow this adjustment.
M. Pull threaded ends of 5/4/3 retract cable, now under the 4
th
section, towards front of
boom.

retract cables will pull through these grooves, use appropriate hardware and fasten
pad plate to the bottom plate of the 3

from pulling through the anchor as the sections are pushed together.
R. Push the 4

th
section inside the 3
rd
section, until it is within 36 inches (90cm) of full
insertion.
S. Install side wear pads with appropriate shims on front inside of the 3
