Far partire in automatico una slide all'apertura della pagina

[s.ef]

Ciao
ho un problema con un template acquistato. Non mi ero accorto che la slide non parte in automatico quando si carica la pagina, ma inizia a scorrere solo se si clicca sulla freccia. ( basta solo una volta e inizia a scorrere correttamente).

Secondo voi è possibile fare una modifica che permetta di iniziare subito lo scorrimento della slide?
Io ho fatto qualche tentativo, ma sono proprio alle basi con Javascript e non sono riuscito.

Vi posto il codice ( spero basti per capire)

HTML:

  <section id="main-slider" class="no-margin">
        <div class="carousel slide">
            <ol class="carousel-indicators">
                <li data-target="#main-slider" data-slide-to="0" class="active"></li>
                <li data-target="#main-slider" data-slide-to="1"></li>
                <li data-target="#main-slider" data-slide-to="2"></li>
                <li data-target="#main-slider" data-slide-to="4"></li>
                <li data-target="#main-slider" data-slide-to="5"></li>
                <li data-target="#main-slider" data-slide-to="6"></li>
            </ol>
