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.

Are you sure the bar isn't bent?

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.

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

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

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

Check your filter on the pressure washer

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"

Thats TOTAL b******s
