#9 Things to do before using a Pressure Washer

Always take time to inspect your pressure washer before every use. Here is a checklist of things you should do before use;

  1. Examine the tires. For pneumatic tires, their ideal air pressure is about 15 and 25 PSI so ensure they are filled up.
  2. Next, ensure the water inlet screen is not clogged or damaged. It is located near where the garden hose goes and helps filter out debris and impurities. If clogged, flush with it with clean water and if damaged, replace it.
  3. Repeat step two with all connectors and accessories. Clogged outlets lead to a build up of pressure within the pressure washer and may cause damage.
  4. Inspect the high-pressure hose and ensure that it is not damaged or leaking.
  5. Next, check whether the detergent setup is clogged with residual detergent. If so, flush it with clean water.
  6. For gas-powered pressure washers, inspect the oil and fuel levels. Refill the fuel tank if it’s low and replace old engine oil as per the instruction manual.
  7. Next, make sure the O-rings are in good condition. They are located in the spray wand. If dirty, clean them and replace them if damaged to prevent water leaks.
  8. Ensure all connections are secure. This includes the spray gun, the spray tips, and the high-pressure hose.
  9. Lastly, flush the garden hose of any impurities and debris before connecting it to the washer.

Important Note

Please read & Follow the instruction manual carefully before using a pressure washer.  This ensures safety to operator and the machine itself.

#7 Things to do after using a Pressure Washer

You should always follow the following steps after pressure cleaning to prolong the lifespan of your washer;

  1. The first step is to switch off the washer to ease pressure from the machine and to avoid unnecessary damage or injury when storing the washer. For electric washers, make sure they are unplugged from the power supply
  2. When off, take out the detergent system. Store the remaining detergent in another container and then flush it with water.
  3. Next, flush the detergent injection tubes thoroughly with water to remove any residue detergent to prevent clogging in the tubes.
  4. Rinse off all grime and impurities left in the pressure washer to leave it ready for the next use
  5. Turn off the water supply and drain the water in the pressure washer by pressing the spray trigger until all water is discharged. If water is left in the washer, it will form a breeding ground for flies, insects, bacteria and mold.

6 Important Routine Pressure Washer Maintenance Tips

Pressure Washer Maintenance Tips

Below are some of the routine maintenance checks you should embrace to ensure your pressure washer is always operating at optimum levels;

  • Lubricating all the inter-connecting pieces. This includes the spray gun, extension wand, and the high-pressure hose. Lubrication protects the connection points of these items from wear and tear of as a result of friction.
  • Inspect the cooling vents of your washer and get rid of any debris that might be lodged in the vents for better ventilation and air circulation within your washer. When pressure washing, the impact of water lodges dirt in the vents thereby blocking air circulation.
  • Cleaning the spray tips and quick-connect nozzles to eliminate debris that may hinder the water outflow.
  • Inspecting for damaged O-rings in the water inlet and outlet connection points and replacing them to make your washer both air and water-tight. Installing new O-rings will prevent water from leaking and hence produce maximum pressure.
  • Examine the muffler on your gas-powered washer to ensure that nothing is blocking the discharge of exhaust fumes.
  • For electric-powered washers, ensure the machine is well-insulated and that its spark arrestor is functioning properly to prevent short-circuits.

Important Tip

If you find your pressure washer is not functioning properly, please do not attempt yourself for repairing unless you found the problem. There are some minor problems which can be repaired without any expert guidance. But for major problems claim your warranty or consult the local mechanic near you.
