I think starting at the point where the thing is on site is wrong.
Most of my problems have been caused before they arrive at site.

Here in the EEC there have been some rule changes with regards to where and when to use. So there are trucks out there that don't comply

Not carrying out site survey properly so customer ends up replacing test head every 6 month at £500 a go


Not using trained people to service these trucks. ( don't think any one untrained is allowed to service by Law)
