177. Pressure Adjustment:To make it easier to check and adjust the pressure, the pressure gauge and the pressure regulator/unloader aremounted on the control panel on the front of the machine. When the high-pressure solution pump is on andprimed, pressure will show on the gauge only while the tool is being sprayed. When the tool is sprayed thegauge will display the pressure being delivered to the tool. When the tool is not being sprayed the gauge willreturn to zero.• To decrease the pressure, turn the black knob on the pressure regulator/unloader to the left (counter-clockwise.)• To increase the pressure, turn the black knob on the pressure regulator/unloader to the right(clockwise.)• To adjust pressure to your tool and surface requirements:o Spray the tool.o Check the pressure on the gauge.o Re-adjust as needed to set the machine at the desired pressure.o Choose the pressure setting that best meets your type of cleaning.Pressure gauge & Regulator/UnloaderTo increase the solution pressure, turn theregulator/unloader knob clockwise.To decrease the solution pressure, turn theregulator/unloader knob counter-clockwise.The maximum pressure setting is 500psi; however,the highest pressure attained is dependent on theamount of water flow at the tool:• Smaller jets and lower flow will allow forhigher pressure at the tool.• Larger jets and higher flow will lower themaximum pressure attained at the tool.The desired setting will depend on the type ofcleaning and tool used. For example:• Carpet Cleaning with 2-jet AW29 wand: 400psi• Upholstery Cleaning with AW50D tool: 200psiIf adjusting or maintaining pressure becomes aproblem, refer to the trouble shooting guide orcontact your distributor for advice or assistance.
