Pressure Washer Maintenance Tips (Pt. 1)

Pressure Washer Maintenance Tips (Pt. 1)

Sticking to a regular maintenance schedule is necessary to keep your pressure washer running smoothly from year to year. Electric pressure washers usually take less effort to maintain than those powered with gasoline, but every pressure washer is different. Be sure to read your machine's owner’s manual for its recommended schedule.

Gasoline-powered pressure washers—Never use them indoors or in any poorly ventilated location.
Electric-powered pressure washers—Make sure your hands and all parts of the machine you touch are dry before connecting to power. Keep all electrical connections dry and off the ground while in operation.

Before Use

  1. Make sure the oil and fuel are full but not over the full mark.
  2. Make sure the water inlet screen is clear of all debris (this will be found where you attach the garden hose). If damaged it will need to be replaced before use.
  3. If your pressure washer has an inline screen check this for debris and damage as well.
  4. Examine the spray gun, wand, spray tip, and high-pressure hose connection to make sure all connections are tight.
  5. Make sure the spray gun trigger and lock are working correctly.
  6. Check that the high-pressure hose is free of any leaks, protrusions, or breaks and that the couplings are tight and free of leaks.
  7. Clean out the detergent siphoning tube and filter.
  8. Run the garden hose to clear out old stagnant water before connecting it to your pressure washer.

After Use

  1. Rinse out any detergent. Remove the detergent siphoning tube and set the spray pressure to low. Flush the system with fresh water for about two minutes.
  2. Release the pressure, power off, and disconnect the water hose. If your washer is electric disconnect the power supply. Run the washer until the water stops, being careful to point the spray gun in a safe location.
  3. Lock the trigger and allow the machine to cool.
  4. Remove the garden hose, spray gun, and wand extension, and high-pressure hose. Drain and dry these items before storing them.
  5. Remove water from the pump. If your washer is powered by gasoline pull the recoil handle around 6 times. If it is electric, turn the unit on until the pump is emptied of water then promptly shut it down.
  6. Remove all debris.
Be sure to only use parts approved by your pressure washers manufacturer when replacing parts.
