Mistake #1: Ignoring Safety Precautions

Before operating a commercial high pressure washer, one of the most critical mistakes users can make is to overlook safety precautions. High pressure washers utilize powerful jets of water that can cause serious injuries if not handled correctly. Always wear protective gear, including gloves, safety goggles, and sturdy footwear. Moreover, ensure that bystanders maintain a safe distance while the machine is in use.

Understanding the Risks

High pressure water can penetrate skin and cause lacerations, while debris propelled by the water can lead to injuries. Familiarize yourself with the machine's safety features, such as emergency shut-off valves, to ensure quick action in emergencies.

Mistake #2: Using the Wrong Nozzle

Another common error is using the incorrect nozzle for the task at hand. Different nozzles are designed for various applications, and using the wrong one can lead to inadequate cleaning or damage to surfaces.

Nozzle Types and Their Uses

• Zero Degree Nozzle: Produces a concentrated spray, ideal for tough stains but can damage surfaces.


• 15 Degree Nozzle: Suitable for stripping paint and removing tough grime.


• 25 Degree Nozzle: A versatile option for general cleaning tasks.


• 40 Degree Nozzle: Best for delicate surfaces like vehicles and windows.

Always choose the nozzle that aligns with the type of surface you are cleaning to avoid unnecessary wear and tear.

Mistake #3: Not Pre-Treating Surfaces

Many users skip the pre-treatment phase, assuming that the pressure washer will handle all the work. However, pre-treating surfaces with an appropriate cleaner can significantly enhance the effectiveness of the pressure washing process.

Benefits of Pre-Treating

Using a suitable detergent or degreaser can help break down stubborn dirt, grease, and grime, resulting in a more thorough clean. Allow the cleaner to sit for the recommended duration before pressure washing to maximize its effectiveness.

Mistake #4: Holding the Wand Incorrectly

Improper wand handling can lead to inefficiency and increased risk of accidents. Users often point the wand directly at the surface, which can cause damage or lead to back-spray that can harm the operator.

Best Practices for Wand Control

Maintain a safe distance from the surface being cleaned and hold the wand at a slight angle. This method not only ensures effective cleaning but also minimizes the risk of injury and equipment damage.

Mistake #5: Over-Pressurizing Sensitive Surfaces

While the high pressure washer is designed for tough cleaning tasks, over-pressurizing sensitive surfaces can cause irreversible damage. This is particularly true for wood, soft masonry, and painted surfaces.

Adjusting Pressure Settings

Before beginning any cleaning job, assess the surface material and adjust the pressure settings accordingly. Using the lowest effective pressure will help prevent damage while still delivering satisfactory cleaning results.

Mistake #6: Neglecting Regular Maintenance

Failing to conduct regular maintenance on your high pressure washer can lead to decreased performance and potentially costly repairs. Maintenance tasks often get overlooked until issues arise, but a proactive approach can extend the life of your equipment.

Essential Maintenance Tips

• Clean the Filters: Clogged filters can restrict water flow, leading to performance issues.


• Inspect Hoses and Connections: Look for signs of wear and tear, replacing any damaged parts promptly.


• Check Oil Levels: Regularly check and change the oil as per the manufacturer's recommendations.

By adhering to a regular maintenance schedule, you can ensure your equipment operates efficiently and safely.

Mistake #7: Using Hot Water Incorrectly

While many commercial high pressure washers offer hot water capabilities, using hot water incorrectly can be detrimental. Users may either not utilize the hot water feature when necessary or use excessively hot water for certain applications.

Optimal Hot Water Usage

Utilize hot water for tasks involving grease, oil, or stubborn stains. However, always check the manufacturer's guidelines regarding the maximum temperature settings to prevent damage to your machine and surfaces.

Mistake #8: Failing to Read the Manual

Finally, one of the most overlooked yet significant mistakes is neglecting to read the operator's manual. Each commercial high pressure washer is unique, and understanding its specific features and requirements is essential for optimal performance.

Importance of the Manual

The manual provides crucial information regarding safety procedures, operational guidelines, and maintenance schedules. Taking the time to familiarize yourself with it can save you from common mistakes and enhance your overall experience.
