I have a Schwing 39 meter Roll-N-Fold and prime it out like a "A" two up and two down. How the hell do you prime out a "Z" that can't go two up two down? Just Wondering...

you might need a sponge in before hand if you have more going downhill than up, but it shouldnt make any difference how the boom is... how are you priming and with what??

I operate a six stage z fold , to be honest its hit and miss if you use a five inch hose you will have no probs but use a 4" and you risk getting blocked in the reducer , prime slow half flow 1000 rpm gets you to the reducer never blocked in the boom .....

i operator 32-5 and prime out folded up.  flat and pumpin at wall speed seems to work for me. 

I have primed everything from a 28 to a 40z in a "Z."  It is all about your previous wash and how clean you got your deck pipe.  When I have had a problem it was easily resolved by not jamming the pump when it did plug and simply putting it back into an "A", sucking back a couple of strokes and sending it through.  That is with a water only prime.  If I ever thought I was going to have a problem or be in a situation like short stick ( by the way great photo) I would slick pack it.

you can prime out a Z boom when it is in the M configuration. water oil and slick pack is all you need. just go full throttle and volume around 7 and you should be fine.

I run a 42/5. i just spray about 5 to 10 litres off water up my cylinders while it is changing over then push it through slow never have a drama in any position. One wise old man told me you next job is only as good as your last.

Hey trey im new to this chat so i hope you get it i have run a 36m Z boom for about 4 years and i prime up in a M if you put everything a about the same angle main up 2nd down 3rd up and fly down about atleast 30 forty feet out you should be fine but i have done it as close as the bumper now when sucking sponge back i have to raise boom almost straight up to get it back

peewee the only reason you have too lift it straight up too suck back is from leaking rubbers.

Yeah usually get them when you have a nice hard block!

? Get what drew

Leaking rubbers.....

 Trey, you can prime a boom in any configuration with a good priming agent or plain ole sac cement or even dirt mixed into mud?

i primed a 42m with 700 ft of system with dirt and diesel fuel no lie

im with johnboy i run a 38 m z in the big m all the time just turn the dial and cracker

I've run a Z-fold for 8 years you can prime out in any configuration,at a 3 or higher but you can only suck back sponge in A-frame.Hell 90% of the time I only use water.
