sorry to post again - didn't get a response last time.
Lance does not focus down any more to a really sharp fan jet.
I am wondering if something is missing from it. The hole in the white nylon nozzle seems fairly large.
Adjusting it changes the jet from feeble to no better than a thumb over a normal hose.
The other nozzle - the one with the rotating jet works fine.
Hoprefully someone has taken theirs apart and can let me know if I am missing something.
I *think* its only meant to go to a sharp fan jet. for the higher pressure use you do use the other nozzle. Having said that, 'no better than a thumb over a normal hose' does sound really feeble - are you sure there are no blockages anywhere? The K2, ready the specs, is quite a low pressure/low volume machine though.
I have used it in the past to clean my patio. It is now useless. I can see down the tube. I have dismantled it and checked the travel of the adjustment.
You've probably already tried this, but as you haven't actually said so, have you tried poking a pin/needle up the hole in the white nylon bit? I had this problem and a pin sorted it, no need to dismantle.

A new end for the lance by the sounds of it ;-)

I can see through the hole. Lots of flow - not enough restriction.
This shows the innards.
I suppose it may be possible that the pump is not delivering enough Volume of water - but the other nozzle seems okay.
If one nozzle works and the other doesn't, the machine is OK. John Rumm is right, needs a new one.

Not in my nature to just replace something without being able to understand what is wrong with it. They are quite costly for what they are.
Various Youtube videos of lances being dismantled Example
At a guess, I would suggest the hole in the end of it is now too big... its been eroded by something - be that time, or grit, or whatever.
I think that is all it can be - but I can't understand how the adjusment really works - perhaps by reducing the "by-pass" around the dise of the jet. On Youtube it looked as though the jet was brass. Mine is white plastic.
Or perhaps white plastic with a missing brass insert?
(I will look at mine next time I am in the garage, and post a photo for you)
Here you go:
looks like it has a brass insert.
This lance:
I just looked at mine. I can see right through it too. It's not apparent how the adjuster works. Do you know some one who has one you can borrow & solve the problem by elimination?
Mine is identical but white plastic.
The whole lance, or the brass insert?
Yes- I will have to borrow one.
The fact that some have brass jets implies that the plastic is inadequate - yet no-one sells spares.
I assume the adjustment works by allowing more water to bypass the main jet.
e one who has one you can borrow & solve the problem by
did you see these?
The whole thing is plastic.
