While R&P focusers vary a bit in design the units I've adjusted (including Tak, WO and Skywatcher) need the same two basic adjustments:
(1) remove the pinion block to adjust the tension on the drawtube, removing any lateral movement of the drawtube;
(2) tighten the nut on the microfocuser to increase load carrying ability, then reinstall the pinion.
The Tak microfocusers can be adjusted without any disassembly using a provided hex key.
I haven't seen the fsq106 focusers and I haven't pulled apart a FT R&P.
