Your machine shares some features with my own - to wind a bobbin you place it on the small spindle on the top at the right hand side.

The spool of thread is placed on one of the plastic spindles on the platform behind the casing. It will flow more easily on the one with the red felt disk as that is a friction reducing device. The thread is led around the metal tensioner, which is at the back mounted slightly above the case level, and brought to the bobbin. A couple of windings around the bobbin will have the thread ready for loading - as long as you wind it the right way. Winding the wrong way results in it being flicked off when you try to start the process.

The trick now is to discover the control which disconnects the motor from the needle and transfers it to the bobbin winding spindle. When the bobbin is full it will be pushed out of winding mode by the shiny metal over filling preventer.

On mine to get into winding mode you simply put sideways pressure on the spindle so it slides to the right with a reasuring click, but on yours there seems to be a button nearby which could perhaps be involved. It could be to engage, or release the bobbin winding mode. Try a few presses and pokes - it won't do any harm - trust me on this - if you exert only gently pressure and have your brain engaged.

The wire guide on the tensioner needs to be rotated clockwise so it is on the other side of the disks about where the numbers 1 and 2 are in the photograph. It is under tension when in the correct position, and you must have released it when fiddling - try to repeat what you did the first time and look for rotational possibilities.

The metal pillar and collar on top of the machine to the left is to control the pressure on the sewing foot. If you open the inspection cover part of the casing on the left - it is hinged at the back and rotates around the vertical so you can change bulbs and clean/oil the mechanism - you will be able to see the spring coiled around the vertical rod. Pressing the pillar increases the pressure, the further down the greater the pressure. Pressing the collar at the base of the pillar releases the pillar and it will rise to the highest position and lowest spring pressure.

You see how the base of the machine is mounted within its case? There is a case coloured clamp at the front right, if you rotate that you will be able to tilt the entire machine backwards on the shiny metal hinges (being careful not to have it collide with anything that might break the spool holding spindles etc) and clean/oil the mechanism beneath the machine. Check the clamp is engaged before moving or using the machine or it could tilt unexpectedly.

Its not rocket science - you can do it.
