8. Nozzle selection
The nozzle on the spray gun that comes with the MAKINEX dual pressure washer is
a ¼ NPT M 15° Size 3.
Your Roto-clean will come installed with one set of 25015 nozzles (25 degree 1.5
orifice).
The minimum orifice to be used in your Roto-clean is half that which is being used in
your pressure washer. Example: If your pressure washer uses a size 5 orifice, you
need to use a size 2.5 orifice in your Roto-clean.
The nozzles being used should have a 15° -25° spray pattern; anything less than a
15° spray pattern can damage the area being cleaned. Anything more than 25° may
not allow the bar to rotate.
Nozzles should be screwed into the rotating bar. The spray fan should be parallel to
the rotating bar.
