How can I fix my cordless 18v battery operated hedg?

Spear&Jackson model number S1851CHX2
Cordless hedge trimmer
Whilst operating this tool the motor just stopped, although if both power triggers are pressed it just
clicks but shows signs of a very slight movement of the blade .
Still under guarantee. Please can you help?

Why even try to do anything if it's under guarantee? Fiddle and you are likely to invalidate the guarantee!
