Has any one got the written instructions on how to fit the manual engagement conversion kit to a Series 1 Powrtouch mover? I've got the kit to fit on a friends 'van but there were no instructions included and I need to fit it urgently. I can't find anything on the Powrtouch website but maybe I'm looking in the wrong place. I've emailed Powrtouch but, obviously, won't get a reply till next week.
