[TowerTalk] Help - US Tower MA-550MDP

[Ken Claerbout]

   I picked up a used tubular crank up tower which I believe is a US Tower
MA-550MDP (55' motorized) with the Mast Raising Fixture (MAF).  It needs a
little overhauling before being placed back in service.  I checked with US
Towers and they do not have any sort of service manual, just something that
sounds like sales literature.  Is there anyone on Towertalk that has one of
these or has notes that I might be able to compare?

Thanks
