I had the same issue and I have now resolved it. The electric pallet truck CROWN did not want to start and the error code SR0 was displayed (startup error). I removed the plastic plate at the bottom of the drawbar. The brake switch (left side) did not work properly because it was clogged with dust and grease (it was always pushed). I cleaned it and then I reassembled it. The error has disappeared and the pallet truck is working again!!!
