Check for stress on the arms. To do this
ix.
loosen the mounting screws (do not remove).
If the arm or the barrel lifts, this indicates
stress on the arm. Adjust the height of the
threaded barrels to reduce or eliminate

keep the arms level and as close (low) to the
projector base as possible.
Check that the projector weight is still as
x.
