1. The rst step is to reset the
unloader. Turn the adjustment
knob counter clockwise until
there is absolutely no pressure
against the spring inside the
unloader.
2. Connect hoses to your pump
and run water to it. Now you will
need to purge the air from your
hoses by pulling the trigger until
only water comes out.
3. Run your pressure washer

running hold down the trigger
and slowly turn the adjustment
knob clockwise.
5. When pressure no longer
increases turn the knob counter
clockwise 1/2 turn and release
the trigger. NOTE: If the engine
stalls or acts as if it is still under-
load then you will need to repeat
steps 4 and 5 again until your
pressure washer goes into by-
pass mode and there is no load
on the engine.
6. Below the adjustment knob
you will nd a brass stopper
with a set screw. Loosen the set
screw and adjust the stopper
until it is snug against the ad-
justment knob. Tighten the set
screw to keep it in place
