Now you’ve got your pressure washer out of the box, you need to know what to do to get it set up. Very soon you’ll be on your way to washing down the sides of your house, your car or preparing that fence to be painted but first there a just a couple of things you should always do before starting work with your pressure washer.

  1. Make sure there is nothing around you that can get broken. Sometimes when a pressure washer starts it can let off huge amounts of pressure and this can send the hose flying away from you and spinning and spitting all over the place. Make sure you have a firm grip of the gun/wand before you attempt to turn the pressure washer on.
  2. Always wear safety glasses while operating pressure washers. They create large forces due to heavy pressure being forced upon the water, this can cause nearby objects to fly through the air if they are hit by the water jet. Always ensure that anyone working around you is a safe distance away from the water jet.
  3. Only ever use the correct equipment with your pressure washer. Never attempt to add or use parts from other models. Every pressure washer is unique and parts from other similar machines will not work properly and can lead to personal injury or damage of the machine itself.
  4. Remember – NEVER LEAVE THE SPRAY WAND/GUN UNNATENDED WHILE THE MACHINE IS IN OPERATION. As mentioned previously there are huge amounts of pressure involved with operating pressure washers. You must maintain a firm grip on your gun/wand at all times.
  5. Check over your battery occasionally to ensure that it is charged. Consider replacing the battery once every 10-12 months.
  6. When connecting your hose, always ensure that your hose is the right size and that it is fully and completely connected with the coupling. If there are any gaps or of the hose is not the right size, your machine will not operate properly and you also risk causing yourself injury and damaging the motor/pump.
  7. Always use completely pure fuel. Some pressure washers use kerosene, some use diesel and some use regular unleaded fuels. Always ensure that you are using the right one suited to your particular model and only ever use the purest form of fuel. Do not add anything to it and if it has been contaminated with dirt, do not use it. Only the cleanest fuels should be placed inside your pressure washer.
  8. If your particular model requires the usage of chemical detergents always be sure to follow the manufacturer’s instructions and once you have finished with using your machine for the day, flush out the contents with clean running water. Doing this will ensure that your pressure washer stays in top condition.
  9. If you have an electric pressure washer always ensure that the electricity supply is turned off and make sure to be 100% dry before you plug it into the mains power. The same goes for when you finish sing your pressure washer, turn off all electrics and be sure that your hands and clothes are completely dry before removing the plug.
  10. If your pressure washer is going to be stored in temperatures close to or below zero degrees, you must ensure that there are no fluid left in the machine over night. If any of the fluids in your machine are ever frozen, do not operate it until they have defrosted completely. To do otherwise would result in catastrophic damage to your machine and a highly increased risk of personal injury. Anti freeze can be used in some models but check your manufacturers instructional booklet for specific details.
  11. If your local water supply is considered to be HARD water, you must use an additional chemical softener to prepare your water for usage in your machine. To fail to do this for extended periods of time will result in built-up residues inside the structure of your machine that will eventually negatively impact its performance.
  12. Ensure that your machine is completely turned off BEFORE you disconnect any of the hoses or attempt to perform any kind of maintenance work on your machine. This is simply to avoid any risk of injury whatsoever.
  13. Make sure your water supply is constant and not likely to run dry. Operating your pressure washer without enough water in-take will damage your machine.
  14. It is recommended that you do not operate this machinery in any confined spaces that don’t have proper ventilation. This is to allow the fumes from the engine (if you have one) to escape properly into the atmosphere.
  15. As tempting as it might be some times, NEVER point your gun/wand at another person. This is EXTRMELEY DANGEROUS and can result in serious injury. People have been known to lose their eye-sight because of the force of some pressure washers.
  16. Do not obstruct the exhaust and ensure that there is sufficient airflow running through the entire machine by checking to see if there is air coming from the exhaust. If there is no flow of air, turn of your machine immediately and seek professional advice.
  17. Keep away from all flammable materials and liquids while operating your pressure washer.
  18. If you notice a dramatic change in the function of your power washer at any time or if you notice a sudden change in the way it sounds, stop operation immediately and seek professional advice from the manufacturer.
  19. Do not operate your power washer while eating, drinking or smoking.
  20. Always ensure that while operating a power washer that you are 100% focused on the job and not trying to do more than 1 thing at a time. Engaging in multiple activities while operating any heavy duty machinery is always a bad practice and can increase risk of personal loss or injury.
