There are no collimation screws on the flt132 objective. The dew shield is removed by first unscrewing the gold ring at the rear of the shield, then the objective may be unscrewed from the tube.
Some of the early flt132's reputedly suffered pinching/astigmatism in cold temperatures as the aluminium cell shrank against the lenses. The cell material was changed to steel in 2013. Also some poor quality objectives made it through QC around 2008/09.
I bought one of these dodgy scopes which displayed obvious astigmatism (flip-flopping ovals either side of focus) and spherical aberration (bright outer ring on the extrafocal rings/star test) and WO let me upgrade to a new objective for US$300.
Yours may or may not be bad scope, don't want to cause unnecessary worry, but I thought my experience might be of interest.
