Hi,
Cannot say if this will help, but I found the operators manual for the UK version of the machine. It is at:
http://www.sitegearservices.co.uk/TB175-E-Ver015.pdf
And I gather they call it ISO/JCB and refer to page 189. It is beneath the cover on the left just inside the door.
It is a 231 pg download. Since it is so large, I will add a picture for you.
Peace,
Clarke
