My ED150DX has arrived, and I find the focuser extremely stiff. It is not due to the lock bolt on the bottom of the focuser. I have searched the internet for info on how to adjust this focuser and found nothing useful. Are there any ED150DX owners here that can tell me how to adjust the tension on draw tube?  I can see various screws on top and bottom but it is not like any past focuser I have owned.

Hi I got this info directly from Skywatcher support: Double check the teeth on the rack and pinion to make sure nothing is in there.

You can also adjust the tension pads on either side of the focuser, those screws are inset and located just above the focuser knobs (see attached). The tension pads are only held in place by pressure so if you back the screws off do it ever so slightly. If the screws loosen too much the pad will drop and have to be reseated. Not a major issue just a little annoying.

Just an FYI, your focuser is the same as the popular Esprit series focusers.
