Looks like it might be a Chinese/English manual though.

check under the feed for tnagled thread in the bobbin area and the shafts

You can get this with google.

Otherwise ask a deep web research service, like manualfox.com
- this is the hassle-less guarantee to get it.

Make sure there is no fabric or thread on the bobbin case shaft. Needle has to be in up position.

You can find the FY811 manual directly from their website at http://www.feiyueusa.com/Manual/FY811.pdf. Hope this helps.
