Maintenance
NOTE: Lift and properly support either
end of boom as necessary to create
clearance between stop plate and boom
support plate before unbolting stop plates
and adjusting shims.
5. Lift and properly support one end of
boom 6"-14" from current position.
6. The spring stop plate nearest the
boom end being lifted should no
longer be touching the boom
support. If necessary, remove shims
until a small amount of clearance is
achieved.
7. Repeat steps 5 and 6 for other end
of boom.
8. Return boom to level condition and
verify that both stop plates are
touching the boom support. Repeat
steps 4 through 7 if necessary.
NOTE: The optimum adjustment is
achieved when both stop plates are fully
contacting boom support when level
(step 4), but clearance is obtained with a
minimum amount of lift distance at tip
of boom.
