How the Pump Works

• Direct-drive axial cam design efficiently converts engine rotation into high-pressure water flow,
  delivering consistent power at 3,400 RPM.
• The integrated unloader valve regulates system pressure by diverting water into bypass whenever the
  spray gun trigger is released, preventing over-pressurization and protecting internal components.
• A manual adjustment knob allows the operator to fine-tune output pressure for delicate surfaces or
  more aggressive cleaning tasks.
• The chemical injector automatically draws detergent into the water stream, improving cleaning
  performance on grease, oil, mildew, and stubborn dirt.
• The maintenance-free crankcase, pre-filled with synthetic oil, provides continuous lubrication
  without the need for oil changes, simplifying upkeep and extending pump life.
