After all excitement I realised there is another problem with the machine. Lift gear mechanism is not able to elevate the tank(empty tank, without reels or chemicals). Video footage here:
Also, after removing the cover it seem to me that modification is made inside the processor. Although I'm not sure if this was attempt to repair or adjust lift mechanism issue.
If you gentlemen came across this I would like to ask kindly yet again what you think can be done to fix this. Thank you.
Perhaps I should just return the machine back to London, it did receive quite harsh external damage during delivery. I can think of scenario with internal construction being cracked..
Nice days to you all,
