I have george vac/shampoo machine and the spray nozzle on the shampoo
adapter is blocked. How do I remove it to clear the the blockage. It all
came to me second hand, with no instructions.

The nozzle will either unscrew, or be held in place by a threaded cap.
Remove the nozzle which may be brass or plastic.
Try not to poke anything hard through the hole - it is very easy to damage a
nozzle and that can give poor spray pattern or lack of pressure. If you can
use a plastic 'bristle' off a garden broom or an airline. Failing that soak
it in vinegar or lemon juice overnight - it could be limescale or chemical
residue.
A new nozzle wont cost much, Numatic parts are cheap as chips.

It's a brass one and my first attempt at unscrewing it turned out be to
a failure. As well as this, looking at the line where the nozzles are, I
though about the re-alignment after removal. Would the nozzles be at the
right angle to the vacuum part.

I wouldn't dream of doing that :-)

It could be something else. Last time I used it, the spray started OK
then immediately backed off about 50%. Right now I can't even get the
plastic pipe off it without cutting it. I am reluctant to do this, as I
don't think there is enough slack in it.
What I might do then, is remove the spray from the vacuum tube and
dangle it in some vinegar as you suggested

Thanks for your advice.

I'd imagine something unscrews. On the machine I have (Non-numatic)
there is a retaining cap/collar that unscrews and the nozzle simply
drops out.
Try phoning up Numatic. They are very helpful and will tell you how to
remove it.

Looking at it, I am certain you are right, but it belongs to the school,
hence my reluctance to force it.

It is resting in vinegar at the moment.
I have had a look at it and it looks like there is a no pressure valve
in the spray nozzle. I have been told that I should be able to blow it
open. So far, I can't.
Failing that, I will do as you suggest and phone Numatic and see what
they say.
This all started when the head mistress asked me to shampoo the staff
room carpet (the staff live there like pigs, by the way) on Friday
night. After spending more than half an hour curing the leaks, I found
that the spray was totally blocked. I won't know if it is working until
Sunday, sometime :-)
Thanks for ever one's input
