Pressure Washer Unloader?
I just bought the Dewalt (DEWALT Honda GX270 3800-PSI 3.5-GPM Gas Pressure Washer-DXPW3835 at The Home Depot) pressure washer.
It has, I guess an adjustable unloader on the pump. (its a black knob directly above the pump)
NOTHING at all is mentioned in the manual about this unloader. In fact, it states that if you want to decrease pressure use a different nozzle or hold the nozzle further away from what you are spraying. I bought a pressure gauge and hooked her up. The PSI is reading 3700. When Im spraying, the PSI drops to 3100 (yes, I know this is normal, so its no biggie. So I "loosened" (maybe an 1/8-1/4 of a turn) the unloader to give me a little less PSI and it worked. I got the PSI down to around 3300......... Buttttt there is a little screw on top of the unloader that has locktite on it and it came off.. Looks like there is only a few threads showing where this screw can screw back on. So is this unloader NOT consumer adjustable to lower the PSI and should I have just left it alone?

Mine is very similar except my knob has a deep recess and the nut that holds it on is hidden behind a snap - on cap.
So I think your nut just holds on the knob. I wonder if it binds if to tight and that's why loctite is used. ..?

I'm not sure why loctite was on there. Dewalt is of no help.
So is unloaded used to adjust the psi on the pump or should I just leave it at factory settings?
