A reminder here:
To loosen the nuts and bolts, hold on the bolt with a spannar and turn the nut. Take out the nut first and then the bolt will be easier. I hope you know what is nut and bolt. Nut is a round thng that screws inside a bolt. A bolt looks like a stick with threads.
Take out the clip with a playar by pulling out from the direction of the purple arrow.
The take out the bolts and nuts shown by cyan arrows.
