Just purchased this M5000. It is a Wild One. Lots of power but not easily controlled. The left pedal (Forward/Reverse) is VERY touchy. We are unable to safely control the low speed of the machine. Also 'Neutral' on the pedal is almost impossible to find and when I do find it it will not stay in that position long. If the wind blows or a grain of sand should fall on the pedal AWAY IT GOES. I have not been able to find information about how to adjust this function. Any of you folks able to help? Thanks ahead of time for any thoughts.
