1. Safety: Always wear eye and ear protection, and read the user manual and follow the safety guidelines. Keep the washer away from children and pets.
2. Positioning: Ensure that the high-pressure washer is placed on a stable and level surface, and ensure that the power source is secure.
3. Water pressure: Adjust the water pressure according to the kind of surface you're cleaning. Higher pressure can damage delicate surfaces, while too low pressure won't effectively remove stains.
4. Nozzle type: Choose a nozzle that is designed for the surface you're cleaning. Some nozzles have a narrow and powerful water stream, while others have a wider spray.
5. Distance: Maintain a safe distance between the surface and the nozzle to avoid accidental damage or injury caused by the water pressure.
6. Detergent: For more effective cleaning, some pressure washers allow you to use detergents to increase the cleaning power. However, ensure to use only detergents that are specifically designed for pressure washers.
7. Power source: Ensure you're using the correct kind of electrical outlet or extension cord, and follow the manufacturer's instructions for your specific model.
8. Maintenance: Regularly clean the washer, disconnect the water supply after use, and store it in a dry and secure place to avoid damage or rusting.
