I know a few of you guys have em...

On the pump, whats the +/- numpty?

Just when I was packing it away after doing my patio earlier, i noticed it, and couldn't be bothered firing it back up again to find out!!

My patio is only 3 years old, and the difference it made was amazing. Really pleased with the results. Can't wait to get stuck in to something serious!

Which pump have you got? Is it the adjustable unloader valve or chem injector maybe?

hmm...so, you have trigger pressure, engine speed, and a pump controller?!

this thing could blow my house down! its mentally powerful with the engine speed up, let alone the pump opened fully!

The engine should be at full revs,.. the unloader really shouldn't ever need to be adjusted as different nozzles are the best way to go.

I dont have the different nozzles on mine (honda sigma) and I find that half revs and 3/4 power on the pump is usually more than enough especially with the lance on.With a fsc it may require more power apart from when cleaning tarmac which i find can leave striping where its been overlapped.

same goes for engine speed.
