    3. OPERATION 3.1 HOW THE PRESSURE WASHER WORKS The electric motor powers the plunger piston pump to pressurize the incoming water supplied by a standard garden hose. The pressurized water flows through an operator controlled unloader valve to set the system pressure.
  • Page 4 3.2 CONTROLS 1. Motor Controls – ON/OFF switch controls motor to operate or not operate. 2. Unloader Valve Controls the system pressure. The unloader is pre-set at the factory to a maximum system pressure. Do not readjust this maximum pressure setting. If a lower working pressure is required, turn unloader knob counter-clockwise.
  • Page 5 Using the chart for nozzle requirements (see Figure 3 below) read across the top to the PSI of your pressure washer then read down the column to the GPM of your pressure washer. The correct orifice size is the number in the far left column. Most manufacturers will imprint an identification code that will tell you the spray angle and the orifice size.
