Hi All,
I'm just servicing a Linde H50D it's a 2006 H2X394S
When I lift or drive as soon as the engine revs up to 1,365rmp
The warning sounder comes on and I get the red engine light on in top righthand corner.
Now the forklift will only lift or lower in slow motion with no drive.
In pathfinder under Traction and faults in memory I get 248.
This stats it has a Malfunction of the engine speed detection.
I can see the see the engine ticking over at 980rpm and when I lift it rises up to 1,365 then drops down and the alarm comes on.

As any body had this problem, could it be a faulty speed sensor?

Thanks for any help.
Paul.
