Change Breakpoint in MaxiMenuCK

Hi, How can i change the breakpoint in the menu? I need to set it in order to get the hamburger menu in the right time. If you look at nieuw.astridtimmers.nl and you change the viewport width, the menu devides over 2 lines which is not my intention..

thanks for you support,
boudewijn
