Hi - I tried the blue disk and my RPM was around 16. With the red disk it's around 24 (still below 28) and it gets stuck frequently. With no disk the water pressure is way too high! The instructions on the Polaris website say to " Make sure that the hose weight adjustment nut is screwed down correctly." But there is nothing in the instructions that says what/where this is. Anyone know where this is or have other suggestions?
Thanks in advance!
