Starting procedures will vary for different engines (see en -
gine owner’s manual). The Honda manual start engine is
very popular on the Wylie Power Sprayers. Turn the engine

If chemicals need further mixing in the tank, open the
agitator ball valve.
Operation

tor valve. Remove the trigger gun from the storage frame
and unroll a sufficient length of pressure hose. Open the
pressure hose ball valve.
Change the pump from bypass mode to pressure mode by
rotating the blue handle clockwise.
Adjust the pressure by turning the pressure adjustment
knob. Screw the knob “in” to increase pressure, “out” to
decrease pressure. The maximum pressure built by the
CDS/John Blue diaphragm pump in 580 psi. Do not set
the pressure above 600 psi.
