Hire Here Dublin how to use a pressure washer

We have petrol and diesel power washers for hire which are ideal for heavy duty outdoor cleaning.  They are a quick and easy way to clean gardens and outdoor areas.

Pressure washers are a pump which runs pressurised water through a hose and forces it out through a spray nozzle or wand. The higher the pressure the tougher the cleaning they are capable of.  They require a steady, uninterrupted supply of water.

Before you use a pressure washer it is important to have the correct safety equipment and be aware of the correct operating procedures.

  • Safety goggles and rubber non slip shoes as well as long sleeved clothing will protect you from the dirt and debris.
  • Keep your work area clear from children and pets
  • Move plants or breakable objects away from your work area if possible
  • If using a petrol or diesel power washer check the level of the fuel
  • Make sure that the hose and nozzle are connected properly and that all the connections are tight.

How To Use a Pressure Washer

  1. Set the spray nozzle to a low or no pressure setting.  This will prevent recoil or kickback when the machine is started.
  2. Turn on the water supply before turning on the pressure washer to avoid damaging the pump.
  3. Start the washer and allow a minute or two for the water to run through the machine and to remove any air.
  4. Hold the nozzle about 2 feet from the ground surface.  Any closer and you risk damaging the surface.
  5. Keep the spray at about a 45 degree angle to the surface.  Holding the spray “head on” or straight will drive the dirt into the surface instead of washing it away.
  6. Work small areas at a time.  It is best to work top to bottom, left to right in long overlapping strokes.
  7. Keep electric lines well away from the work area
  8. If using a petrol or diesel washer, switch off the engine and allow to cool before refuelling
  9. When you are finished, stop the machine, turn the water off and make sure to remove any remaining water in the hose.

Important to Remember

  • Never use a pressure washer when standing on a ladder
  • Keep your hands away from the water stream and don’t point the spray at people or pets. The pressurized water can cause serious cuts and other injuries.
  • Don’t spray windows or glass objects like patio table tops. The high pressure can shatter the glass.
  • It is not advisable to use pressure washers in an enclosed area.  If it is necessary make sure the area is well ventilated and there is a carbon monoxide alarm fitted.
