Lift the presser foot and tension is bad

[palvim]

Hi All
i have seen on so many videos where people lift the presser foot to see the exact position of the needle or while turning. And nothing goes wrong. The next stitch has perfect tension. 
When I even slightly lift the presser foot, the next one or two stitches are bad where the tension goes off. Bottom thread starts showing on the top. Why is that? Is there something I’m missing why others seem to have no issues doing it but mine always gets bad? 
I’m using an Adler 269-373 as well as a 267-373 machine. 
Thanks for the help. 
Vimal.

Make sure when you are turning that you have gone past the bottom dead centre and the needle has risen about a quarter inch to make sure the hook catches the top thread loop and doesn't drop it.  That is when it skips a stitch.

When you lift the presser foot, just lift is slightly while making your turn.  Lifting it too far releases the top tension disks, thus you lose top tension. 

Usually, when you lose the top tension, it doesn't pull the bobbin thread up to the top, so maybe my answer is way off base!

Many machines release tension while lifting.  Most can be adjusted so thread releases at the top of lift.  Usually the tension can be adjusted by the screw holding the the mechanism.  Many such as Singer 45k and 144w don't even have this feature.

Could you please share how to do this so the thread is only released at the top of the lift?

The circled in red is the adjustment screw.  Back  out tension assembly by loosening screw. Some times I have had to loosen the screw at top of assembly and insert a washer.  Other choices would be to shorten the pin that inter acts with release mechanism.
