Just bought one last week but yesterday it started wobbling about and the machine kept stalling. Both are new so not sure if I'm doing something wrong? Connected the 18" which I've rarely used for 2 years and both operated fine.
Any info would be appreciated.

One of the jets is blocked so firing out of only one??

Did you turn it on its side and check?

Only enough to see water was spraying! An unbalanced wheel was what came to mind so one jet blocked would probably be right. I'll check that tomorrow.
How would you go about unblocking it?

I remove the nozzle and poke a needle in it.

Just had a look and one of the nozzles is 50% further in than the other which surely isn't right.

[Rob@Blast off]

Are you sure the bar isn't bent?

[wpclean]

Been drinking ?

The screw thread is in further on one side. It's brand new and only been used on level surfaces.
I'll take both off and make sure one isn't blocked like Mike said.

[Rob@Blast off]

just hold the bar and fire it up, that way you'll soon see the problem

Maybe get someone else to hold it!

Right its not a blocked jet and is running on a lower pressure, as soon as I turn the pressure up the machine stalls
whirlaway is rated for 4000psi and around 31 litres per min. The pressure washer is 14hp 3000psi 21 litres per min.
I've recorded it but unable to upload as of yet.

It won't let me see the video? Can anyone else see it

[chris scott]

Put the right size nozzles in it.

At last the clip is available.
Basically the machine was ordered with the 12" rotary and hose and gun which separates from the lance, so machine runs as it should until the 12" rotary is connected and when on full pressure it cuts out.
The machine and the rotary have not been modified or adjusted by myself.

I agree with this,

my machine stalls if I try and use it with too small a jet, unscrew the jets and try it.....see if it stalls

[Ben Marriott]

It should have been jetted by whoever you bought it from...  should be on 03/035's

[wpclean]

You need a degree in advanced mathmatics  to work out pressures, and nozzle sizes in this game !     I am too thick to understand most of the technical stuff, so is good to have you guys who know their stuff 

[Paul Moss]

Check your filter on the pressure washer

[Plankton]

He has said the nozzles are smaller on the 12" so to reduce the pressure and turn it up to the 'sweet spot'. The box says 4000psi and about 31 litres per min so I never thought about nozzle sizes affecting the machine.
I was working on a lower ground patio (Saturday) with access via ladders, so going up and down ladders and over a fence to restart the machine several times was a bit of pain. In the end I had to use the 18"

"He has said the nozzles are smaller on the 12" so to reduce the pressure and turn it up to the 'sweet spot"

Thats TOTAL b******s

You should have gone to specsavers….
Sorry you should have gone to Rutland pumps (Rutland Pumps Limited - 01572 729303 - benm@rutlandpumps.co.uk)
Was the supplier  an Irish or welshman?

Pointless reply!

[Ben Marriott]

In all seriousness you need it jetting properly by the person who sold it to you free of charge - there is no way you should have to touch anything on the machine to make it work... thats just not cricket

[Plankton]

Firstly my wrist is nackered so I'm unable to remove the jets to replace even if I had replacements.
Secondo the rotary cleaner is rated to 4000psi and 31 litres per min and set for optimum efficiency by the manufacturers. So I would have assumed that the jets could cope with only 3000psi and 21 litres per min.
There must be an abundance of people on here that have this equipment so what jets have they got fitted?
Get your Specsavers goggles out and let me know 😉

Phone Ben on 01572 729303  Quoteing pump make and model . You will also need the thread size for the nozzles 1/4 or 1/8 bsp
Who supplied the FSC ?

The machine is RATED to that pressure and flow but to get it to work on your machine it has to be JETTED correctly - without knowing exactly what pressure and flow your machine is producing - NOT necessarily what the pump says it is capable of we can't tell you what jets you need. We can guess? @ 21lpm 200Bar you should be on 035's

I will try it tomorrow on a very small job and see how it goes, if it's not bobbing about and cleaning as I would like I will look to take this up with the supplier.  I'm concerned about the jet that's protruding more than the other and the fact it has some sort of adhesive around the thread although this could be the new PTFE that a plumbing merchant told me about.
Thanks for the info chaps and if ben reads this I can't see the 12" replacement bar on your site, just in case it breaks if I need to replace the jets.
H9 is the only marking on the jets dose this indicate anything?

We do the bar but no one has ever killed one yet so is on he very long list of to be added products!

The adhesive will be loctite or thread locker - they should be in a roughly equal distance but it is not crucial to be mm perfect. Odd jets is usually just slapdash installation - H9 could be anything - a photograph would be the best help

[Ben Marriott]

Having looked at his machine probably jetmac or the guy in London that sells them for terry

[Plankton]

Used the rotary today with the pressure turned down and then increased like he said.
So the result is no pw stalling and no wobbling rotary and mono block came up good.

Excellent glad you sorted it out …How long is the warrenty on equipment you bought? Did you buy the FSC fro m the pressure washer supplier?

[Ben Marriott]

Excellent glad its sorted - be careful on the unloader wear from running in bypass constantly though.

[Plankton]

Excellent glad its sorted - be careful on the unloader wear from running in bypass permanently though.

Permanently?  I wouldn't think everyone runs there machine at full throttle and full pressure permanently though. Doubt it would affect warranty either.

[Ben Marriott]

If you are restricting the flow with the unloader it will be in bypass which as a rule is not ideal. Adjustment on throttle is fine

Your just taking the pi%% out of use by asking for advice…you already know the answers.
