Gizmo on Ciasons SP1804S compressor between head and transfer tube
(San Diego, CA)
Gizmo from Ciasons SP1804S air compressor
Just lately, I got wondering about this.
It is on my Ciasons SP1804S.
Pin thing pops up while running, drops at cut-off.
Holding it down doesn't seem to do anything.
It does have check valve/unloader at the other end of the tube at the tank.
Any idea what it is?
