Hi, Ive just joined the forum from Guernsey, Channel Islands. Ive had a UFORCE 500 for about 3 years, its used mainly off-road for moving sheep and goats, collecting feed and general work tasks (moving fencing, soil aeration etc). Ive joined to get hold of the service manuals as my OPC sensor has a fault and the buzzer keeps going off even when sat in the vehicle - I would cut the buzzer off if I could find it !!!
