Doing a preventive checkup of the equipment.

Several components are required to make sure that the pressure washer is working efficiently. One of them is the engine oil. Just like your vehicle, you need to always check the engine oil before use.

Change Oil

If the oil and fuel are low, it is time to change the oil. Make sure you use only the factory-recommended oil to ensure that the device runs well.

Check the Screen Display

Another part that you need to check is the screen. If it is clogged or dirty, use clear water to restore it. You can also replace it with a new one if damaged.

Hoses and Couplings

Other parts that you need to check before use are the hoses and couplings. Make sure that there are no cuts, abrasions, or leaks on the hose. Your hose must be in good condition so it can handle the high pressure of water.

Conduct maintenance after each use.

When you are done using the pressure washer, do not just store it back to the garage or warehouse. You need to flush the cleaning detergent solution that you used for cleaning.


Run it through the clear water to ensure that you do not leave any remnants behind. When that is done, shut down the entire pressure washer system. Once the engine is completely shut off, allow it to cool.

Cooling Down the Pressure

At this point, you need to relieve the pressure from the system. Hold a spray-gun trigger to ensure that all of the water is expelled. Disconnect the hose from the pump and make sure all pumps are empty of any type of liquid.

If not, even the smallest amount can cause damage to the pressure washer parts over time. You can also try pulling the recoil handle a few times.
