Skywatcher focuser upgrade / motor

[guydive]

I have the Skywatcher 10" flextube goto with the regular focuser which I upgraded with a little motor of this kind for camera use (EAA basically)

when I want to use it manually (for visual observations) I just need to loosen the little Allen screw that hold it:

 

Now I ordered the Skywatcher dual speed focuser and plan to install it the same way. 

my question is, can I loosen the motor for visual use in the same easy way? 

I see holes at the bottom, but not sure if they are located at the right spot:

I just attached a Lakeside focuser to a dual speed on my 300PDS, I used the large focus lock wheel with some washers to hold the focuser in place. You could still slacken off the grub screw to focus by hand but I just use a hand controller to move the focus tube and then I'm not risking dropped grub screws, stripped threads and I'll get better focus than I can manage by hand
