yes it does. Thank you for asking
John Rudd:
Just make sure you fit the new fuseholder.....and... Fwiw, despite what fuse is fitted, change it to a 3 amp fuse.....These machines tend to be shipped with fuses with a rating higher than necessary.
The result is either a blown control board or motor or both.....you could also check the fuse in the mains plug....again no more than 3 amps should be sufficient

thanks John
i know for definate that the fuse in the plug is a 5 amp so i'll do that straight away.
John Rudd:
So, what is the justification for a smaller fuse?
Simply put, watts is volt x amps.
The motors on these small lathes are around 300-400 watts. So at max load they will consume no more than about 2 amps....Generally the speed controllers have in built protection to avoid over current, but should something go awry, last level of protection is the fuse....
Thats my take on it and as it happens, is the same approach adopted by Warco, I'm told from sources on another forum
