Before you start your next pressure washing chore, it’s important to make sure your pressure washer is ready to go. It only takes a few minutes and could save you from needless frustration.

  • Empty the detergent tube and tank.
  • Inspect Hoses, o-rings and couplings for dents and damage.
  • Check spark plug for excessive carbon deposits, proper electrode gap.
  • Be sure to use fresh gas and oil; this is especially important if your pressure washer has been unused for long periods of time.
  • Inspect air filter, spray guns, hoses and belts for cracks.
  • Check all the nozzles and tips for clogs.

  • Flush the chemical/detergent system with water until water running out of intake is clear.
  • Clean dirt, debris and grime that have accumulated on pressure washer or components.
  • Drain water.
