Hi there

Thanks for the reply. Its a 2001 model i think but thats the info i got off the truck plate.

However managed to get to the bottom of the problem as under the foot plate/dead man switch there were a lot of wires which had come loose on the connector so after crimping them and plugging the connector back in resolved the problem.
If anyone has a manual for this would still be useful as the customer has a few of these and can be prepared for any future breakdowns.

Regards
