I disconnected the foot control. I-Piolet works OK now.
I'm not real sure what screws on the bottom to remove.
Just don't want to make it worst / not get it back together correctly.
Since we are Leaving Friday for MN fishing trip for "fish with teeth",
I may just wait on trying to disassemble the foot control till we get back..
Thanks Rick.

Just remember lavender scented soap really does work to repel ants.
