Rotors on most trimmers I have ever used have a cable with a lever to change direction, most have a little lever that you need to move first so direction cant be changed by accident at speed blowing the motors etc (sorry if you know about the lever wasnt trying to patronise)Hi all. I have a problem with my mcconnell pa6570t. The rotor only turns one way. Have been told to check the soleinoids and valves and all these seem fine. Any ideas?
