Quinny buzz how do I put the tyres in the quinny buzz,and how do I open and close it thank you

Tyres-press the light grey button on the chassis next to the wheel slot as you push on the wheel (this is also the button you press to release each wheel).
Opening it is easy - With Buzzwheels on the ground, remove safety hook (plastic loop on left side of handle fixed to peg inner left rear wheel) ten simple lift handle and Buzz frame should automatically pop up.
Closing takes more practice-put on brakes (press red foot pedal) stand to side of chassis and at bottom end of handle there are two large grey buttons. With left hand on left button push button forwards (ie direction of chevrons on button) then press in. At the same time push in right button with right hand. Whilst doing this you also need to push down and forad on frame and it should fold down. If you don't push buttons enough it can click. When folded remember to put on safety hook before transit, otherwise it might pop up on its own. Hope this helps. You can download the manual with instructions from Quinny website too if pictures are helpful!
