BOLTED FOLDY PROBLEMS.

Hey, im new to scootering and have just bolted my foldy.
the bolts were slighty small but fit perfect. It lasted for about a week. until i like bunnyhop or air on a quarterpipe my scooter makes an awful crutching noise at the folding mech? do i need to tigthen something.

P.S - I ride French ID!
 
tighten the bottom bolt a bit more, and tighten the top one a bit more, dont tighten the middle to much incase the foldy bends
 
Thanks Peeps. I haven't got washers just standard nut on the side of each bolt. i've tightened them and its alot better. Jondogg I live in Surrey Near london.
