Inside the control box and under the front
panel, find the relay cube for the pump. It is
found near the middle, left-hand side of the
box. It is a clear yellow cube with a green
button facing the top of the control box.
When you press this button, material
should dispense from the wand, so be
careful.
Does the material pump shaft coupler turn
when you press the green button?

Yes, this tells you that everything from the
cube relay to the hydraulic manifold is

hose and wand. Go to
