Safety Instructions
Always wear protective gear, including gloves and eyewear. Ensure the area is clear of obstacles. Read the manual thoroughly and understand engine controls before operating the pressure washer.
2.1 Important Safety Precautions
Always wear protective gear, including gloves and eyewear, when operating the pressure washer. Ensure the area is clear of obstacles and bystanders. Avoid using the washer near open flames or sparks. Never point the spray wand at people, animals, or windows. Use the widest fan spray nozzle (40º) for surfaces sensitive to high pressure. Keep children and pets away during operation. Ensure the washer is placed on a stable, level surface. Do not use the washer in enclosed spaces or near electrical sources. Follow all safety guidelines to prevent injury or damage.
2.2 Proper Use of Nozzles and Spray Settings
Select the appropriate nozzle based on the cleaning task. The 40° nozzle is ideal for delicate surfaces like windows and siding, while the 25° nozzle is better for general cleaning. Use the 15° nozzle for heavy-duty tasks requiring intense pressure. Avoid using narrower nozzles on sensitive surfaces to prevent damage. Always start with the widest spray setting and adjust as needed. Keep the spray wand at least 12 inches away from surfaces to avoid etching or stripping. Regularly inspect nozzles for wear and replace them if necessary to maintain optimal performance and safety.
Assembly and Setup

Next, install the desired nozzle by pulling and twisting until it clicks. Finally, add the recommended oil and fuel, following the manual’s specifications. Double-check all connections and settings before initial use to ensure safe and effective operation.
