Darran I think the fsc is leaving a mark on the concrete,  not in all places but in some. I hypoed it and rewashed twice and its fine now in most places. Any ideas why fsc would do this? Lot of different lads have been on the machine last few weeks. Could damaged t bar or something else cause it. The nozzles are old but not blocked.

If  the nozzles are old - they could be worn - be worth putting in a new set. - you can check the angle they are set at.
bent bar unlikely - you would feel it (like a bad tyre on a car) and would be consistent whoever was operating the FSC

it could just be the operator rushing in these areas - as simple as that

It's not rushing anyway Darran as mark in concrete and turbo won't even change that. There is no markings on nozzles what size of nozzles are optimum for fsc?

[Smudger]

you mean the marks are left physically by the FSC ? - you never noticed it scraping the concrete at 800 RPM?

again I would say that would be a constant mark all over - not here and there

Thought you said that stuff cleaned before and after that section was ok ? I agree with Darren I would replace the jets to be on the safe side make sure they are the correct ones for your  pw  output , it’s a very cheap try and hopefully will fix the issue

Now both those sections are side by side done  30 mins ago.

It was Splash. Just washed a section with turbo only now and going to go back over little bit with fsc to see if any discrepancies

They look like different mixes of cement by the colour, it’s always difficult to tell from pictures but it does look like organic staining , keep us informed how it goes . Never had this happen.

Will be back there Thursday.  Its definitely not organic and my fsc doesn't seem to be marking it either after testing it this eve.  Then to add insult to injury fsc would not run properly before we finished prob half  power ,whereas lance same pressure as normal. Nozzles not blocked what could be cause of that? Never get any hassle had enough last few days to last 6 months

Definitely completely different mixes in places.

Have you greased the head recently? If the grease goes hard it will slow it down if that’s the case clean it out with wd40 then re grease pushing all the dirt out of the head and bearings  it should then work as new , we do this with ours every couple of months

Thanks Splash I greased it yesterday but not this morning. I'll do that.  Thanks for that, I appreciate it
