15 Most Common Mistakes People Make With Pressure Washer


With pressure washer, you can do all of those tasks that would normally take hours and minutes with the use of a pressure washer. I have a lot of friends who work on cars and they use a pressure washer for them to wash their vehicles. That way they can easily get all the dirt off without having to spend so much time scrubbing. A pressure washer is a great tool to have if you want to clean something fast and efficiently! Own one for yourself with a 2 year warranty!

When using a pressure washer, it is important to be aware of the many potential mistakes that can be made while operating it. A pressure washer can be a great help in the cleaning of your home, but it is still an incredibly powerful tool. Here are some mistakes that people often make while using one.

By following these safety tips, you can help avoid costly and dangerous mistakes.

1. Not reading the manufacturer’s instructions

It is important to read and follow the manufacturer’s instructions when using a pressure washer. Failing to do so can result in damage to the unit or injury to the user.

2. Pointing the nozzle at people or animals

Never point the pressure washer nozzle at people or animals. The high-pressure water can cause injuries such as eye injuries, skin abrasions, and even death.

3. Not wearing safety gear

In addition to following the manufacturer’s instructions, it is important to wear personal protective equipment (PPE) when using a pressure washer. This includes safety glasses, gloves, and appropriate clothing.

4. Not cleaning the surface first

Before using a pressure washer on a surface, it should be cleaned. If there is dirt or other contaminants on the surface, they can become embedded in the material being washed and may damage it.

5. Not turning off the machine before removing the nozzle

When removing or attaching a spray tip from a trigger gun, always turn off the pressure washer engine and wait for all moving parts to stop rotating. This will safely remove compression from internal components of your unit if you attempt to do both while under pressure.

6. Using the nozzle at too high of a setting

When using a pressure washer, it is important to start with the lowest pressure setting possible and gradually step up if necessary. High-pressure water can damage surfaces and remove components from equipment such as lawn mower blades.

7. Not checking for gas leaks before starting the engine

Before attempting to start a pressure washer that has been idle for more than 2 months, inspect the machine for signs of fuel leakage. If there is any sign of fuel leakage, do not attempt to start the engine until it is repaired by an authorized service center.

8. Operating in wet conditions without footwear or appropriate clothing on

It is best to avoid operating a pressure washer in wet conditions as it can make footing more dangerous. In addition, wearing appropriate clothing will help protect the user from injury.

9. Making unintentional contact with moving parts

When using a pressure washer, never touch the engine block, header tank, high-pressure hose, or any moving part of the machine unless instructed to do so. Moving parts can cause serious injuries if they come into contact with skin or clothing.

10. Failing to verify that nozzles are installed correctly before starting the pressure washer

Before starting a pressure washer, check to see that all nozzles are securely fastened and not obstructed by debris such as dirt or other contaminants on surfaces being washed. An obstructed nozzle can damage the pump and void the warranty.

11. Failing to wear safety glasses

It is important to wear safety glasses during use of a pressure washer as they can keep debris from entering your eyes that could otherwise cause injury.

12. Mixing incompatible chemicals in spray solution tank

When using different types of cleaning solutions in a pressure washer, it is important not to mix them together in the spray solution tank because this will contaminate one or more of the solutions with another chemical. This will make them ineffective for their intended purpose and could also pose health risks when used around people or animals after washing surfaces.

13. Operating without water supply connected

Before starting a pressure washer, ensure that the water source is properly connected to the pressure washer pump. If not, use of the unit can damage internal components and void its warranty.

14. Not using appropriate nozzles for each cleaning task

For specific types of surfaces, it is important to use an appropriately-sized nozzle that will produce enough force to clean the surface effectively without damaging it. For example, if a nozzle produces too much pressure on a dirty surface, it can damage or remove small components on equipment such as lawn mower blades.

15. Pulling hard on high pressure hose

High-pressure hoses are under a great deal of tension even when they appear slack so do not pull hard on them as this could cause them to rupture or come loose from the machine. When disconnecting high-pressure hoses, always turn off the pressure washer engine and release any residual pressure by depressing the spray gun trigger. This will safely remove compression from internal components of your unit if you attempt to do both while under pressure.
