Hi Olly,
I am in wombwell, tother side of Barnsley.
I have ex training Boxford lathes so cant help with the Chester. But you should be able to get a manual either electronic version or paper. Especially as it's a relatively new machine.
If you need anything turning to get your machine is up and running give me a shout.
I'm a self taught tinkerer not an engineer but I will tackle most things.
Just rebuilt a garden tractor and made lots of replacement parts for it.
See thi after't lock darn.
Mick
