Hello, I have a problem with the machine. It starts to run slowly, but it can climb hills with little torque and speed. How can I check if the problem is with the pump or the motor? I immediately disassembled the pump and had it repaired by a specialist, but if the situation recurs, how can I perform all the necessary tests? With thanks and appreciation.
I doubt many, if any, members on here are familiar with this type of vehicle.
