So, on the back of this pot, here, you’ve got the pilot valve. You got the positive air that I mentioned. This is identified by being red — red hose, red fitting, quarter inch, quarter inch.
So, this swivel nut will retain your dead band. As I mentioned before, their brass fittings, be careful not to over-tighten them or cross thread them. So, these you return signal air that goes on like so.
So, now, I have appropriated this to activate the pipe. These must be tight though, not overtight, there’s no need to. Appropriate fenders to do the job would be a good idea.
Also, there’s nothing wrong with using shifters for this. But it’s important to remember this too. When you do this swivel nut up, it’s important to remember. Look, the whole thing wants to turn, so just hold that bottom nut. Hold it still and nip the swivel nut up like so. That way, the olive goes into the seat. It marries and it’s tight.
So, the only thing is moving near now is the hose on the end of the hose tail. So, what I will do is the pot tender when the operator actuates a deadman. I’ll just check them for leaks as well to ensure that I’ve got them.
Nothing wrong with the squirter bottle with a little bit of detergent and water to ensure that I have a seal there and moisture doesn’t escape unnecessarily and undermine the operation of the deadman. So, there you go just nip them up nice and tight. No problems at all.
So, we’ve got a nice tight hose arrangement here. Arrange that in a way that it’s not in your way in. Don’t trip over it.
So, if you follow these simple steps on keeping it clean breather, make sure that all of this actuates properly. You won’t have any problem. Don’t forget to make a breathe or let it breathe.
Now, say for example, this one of these hoses didn’t work properly. What’s the consequence if one of these didn’t work, and I say that it had a hole in it, had a split in it?
When the deadman is opened or operated, the signal could no longer be appreciated by this particular valve. So, therefore, it becomes confusing, this operation that may not open properly, or may not open at all.
So, how do I find out what’s going on? From the deadman handle all the way back up this line. Follow this line for anyhow — for crimps, cuts, abrasions, and so forth.
When you come back to this particular valve here, that’ll tell you whether you’ve got
positive air or not.
What do you mean it’ll tell me it’s good positive air? Well, if the dead man won’t activate and I think the myself on how do I find out these valves alright? All you need to do is undo this particular feed hose that goes to the auto air valve and you notice, I’m using two spanners so that I can undo the pair of them at once and hold them still. Because if I try and do it undo it with just one spanner, the whole thing will just spin around.
So, if I get this other spanner in here and hold that hose fitting, I can undo it and remember, righty-tighty, lefty-loosey to get this undone. Now, sometimes when they’ve got a bit of moisture around them from the rain or the elements; and/or that they’ve got a bit of grit in amounts of the tread, you might find you need to undo it all the way
with the spanners.
You can use smaller ones, of course. I just like to be different. So, once I undo this, what am I doing? Well, it’s giving me the opportunity to see why the deadman is not working and this is the quickest and easiest way to do it. Because if the deadman is not working that means I’m not getting signal air and the signal air needs to come from this particular item.
So, this pilot valve here is telling this black box. This pilot valve is telling the whole pot what to do in relation to actuation.
