Has renovated the hydraulic lift, and now the arms go slowly. But if I pull the outer hydraulic lever, backwards, then the arms begin to move at the right speed again.
And if I bring the lever back before the arms are in the top, the arms will stop for a short while and continue at the right speed when the lever is in the middle position again.
When I then lower the hydraulic arms and raise them again, they go slowly again ..... and then you have to redo the procedure.
Before the renovation, this was not the problem. Does anyone know what has happened or what is wrong? Hope you understand my bad language!
