Thank you Steve, that answered my question about manually retracting slide. When it quit Monday we were in the backwoods of Maine. No cell,no internet,no way to call for help. It is now working fine. I have spoken to pump mfr and they said you can remove the motor endplate, carefully and inspect,clean brushes. They cannot be replaced without removing mtr,which I dont want to do without replacement in hand. By the way I think we met last summer in Winnemucca ,at New Frontier. I was parked across from you.?
