If it is computerized, they are generally sealed so they cannot be opened by the user. There are computerized components that could easily be damaged. The manual should have instructions how to maintain your machine. AVOID using compressed air as it tends to push lint and dirt further into the machine where only a technician can clean.

Adjust the bobbin in what way? For what purpose?

Lint and or thread has collected behind or under the bobbin. use a q-tip (cotton) and swipe out and around the bobbin and bobbin case. Use a can of air and blow out and around the bobbin area. Remove the spool thread from the machine and rethread the spool and bobbin thread in machine.

This happened to me on several occasions and finally one service tech told me not to use the needle down auto button. Instead when threading the bobbin just move the wheel toward you slowly until the thread catches.

Despite what the instruction book tells you, do not use the auto downup button to pick up the bobbin thread. Instead pull the wheel toward you and do it manually. Many times the bobbin thread gets caught and the machine halts if that auto down button is used.

More likely, you forgot to hold the bobbin and top thread ends together behind the presser foot when starting a seam. See: http://www.picturetrail.com/sfx/album/view/22521551
