It has come to my attention that some guys don't know how to (im)properly drain the air from a doggie dollie. Evidently some person in wilmington thinks it is fun to stand bent over draining the stupid dollie air tank in the rain/snow...

This exercise assumes a correctly hooked set of doubles with a "Doggie Dolly" inbetween the 2 big trailer thingy's.
Tractor setup-
Yellow button out, tractor parking brakes SET.
Red button left pushed in.
Trolly valve pulled down like you were doing a brake check.
At the dolly-
Shut off red & blue valves.
Remove blue & red line from rear trailer, put them in the basket with the electrical cord holding down the blue line.
Slowly turn the blue valve back on until you hear air escaping from the rear blue line.
Go crank down your landing gear, pull the 5th wheel release.
By now the air escaping from the blue line should be a much smaller amount than when you turned the valve on.
Turn the blue line off.
You will need to vent approx 5 seconds of air from the air tank to fully release the brakes.
This works on approx 95% of the great dane dollies. The ones it will not work on are unidentifiable unless you try the above procedure & it doesn't work. If you hear the low air buzzer come on in the cab, it's not gonna work on this dollie.
BOL
"Great" another Dane dollie...
