can you stop shouting in upper case
there is no "earlier version" of the rotex 125, the existing rotex 125 is the first model
the new version rotex 150 looks like the rotex 125 with similar controls
i have the original version of the festool rotex 150, ive customised to suit the way i use it
my information has it that the rotex 150 was never sold under the brand name festo, the original rotex 150 was introduced only after the company was rebranded festool
no you cant have it
nor will i swap it for your rotex 125, because i have one of those as well
by the way my information has it that
however there is a solution to your problem, get it fixed by festool
