For Information of those using Feathertouch focusers:
Only use the thumbscrew under the focuser to lock the focus in place, Do Not engage it partially and then move the focuser..... Kent had a new FT3545 fitted to his TEC200 that failed as he had been using the thumbscrew to adjust tension (as instructed) but this causes wear that requires full dismantling and parts replacement..... Wayne and Jon declined Kent's warranty claim saying that he had caused the damage and it cost $300 USD for the repair...
Draw tube tension must be adjusted by the socket screw on top of these FT focusers.....
I have just adjusted two of my three FT focusers so that the 'tension screw' does not need to be touched unless I really want to lock the focuser....
Here is some light reading for all FT users:
