I use it to wash out the ends of hoses when I have to do an emergency repair with a reusable fitting, cleaning the angle grinder grit out of the hose end.

I really can't believe that a safety device, the lifting barrier, is wired through the ECU. That a computer malfunction could stop it working just isn't on. Really ought to be a mechanical device attached to a hydraulic valve to stop any oil flow. Even a switch can easily fail.

Thanks, I was wondering what the Kubota red and black keys are for after looking at the one in the auction.
when lifting lever it cut engine revs and reverts all your settings to a standard dig mode would tell me its linked with the ecu some how and in terms of safety that would tick a lot of boxes as you can't do what Rory is suggesting as a temporary check permanently
