First place the thread spool on the spool holder and secure it with the spool cap. Bring the thread to the left and snap it into the thread guide. Wind the thread clockwise around the bobbin tension discs. (Bring the thread to the right side of the discs and and then around the discs. Bring the thread to the right and then insert the end of the thread into the hole in the bobbin. Make sure that the hole is facing up. Place the bobbin on the bobbin spindle and push the spindle to the right. Hold onto the thread that is above the bobbin and step on the foot pedal to start winding the bobbin. When the bobbin is full enough, stop pressing the foot pedal (or wait for the machine to stop winding the bobbin). Cut the thread and move the spindle to the left. Remove the bobbin from the spindle.

Do you mean the Singer 4411 Heavy Duty sewing machine? If so,
first place the spool on the spool pin with an appropriate sized spool holder, if you are starting the project. Snap the thread into the thread guide to the left of the of the spool pin. Wrap the thread clockwise around the bobbin winder tension discs (slightly to the left and forward of the thread guide). Bring thread towards the bobbin spindle. Thread the bobbin (put the thread through the hole in the bobbin). Place the bobbin on the spindle with the hole up. Move the bobbin spindle to the right. Hold onto the thread above the bobbin and step on the foot control pedal. When the bobbin finishes winding the thread, cut the thread at the top of the bobbin and the incoming thread from the spool. Move the bobbin spindle to the left and remove the bobbin. If you have already threaded the machine for sewing, you will need to remove it from the various guides and tension discs that are used in sewing. Then after winding the bobbin, re-thread the top thread.

The directions to wind the bobbin are in the manual on page 12 (page 19 of the PDF). You can find many Singer manuals at the Singer support page: https://www.singer.com/support .

Not sure what you mean by "vertical" bobbin. Everything I've found indicates it is a top loading bobbin that sets horizontally in the machine.

Ok which is it? A Singer or a Necchi?

If it is a Singer or a machine like the one picture here.... slide the grey metal plate toward you. You'll see the "drop in bobbin" Look for a little lever or button that will lift the bobbin up so you can get it out.

There are a load of threading diagrams HERE, although your model is not listed, one may be similar enough to get you out of trouble.
As to a manual, a google search should give you several options for pdf downloads

Check the thread coming out from the bobbins maybe on reverse side,also check the bobbins tension adjust it there is a small adjusting screw.Check also the needle alignment lastly check the upper tension from the tension regulator knob,tension adjustment is depend on the fabrics that you sew.
