NOZZLES Nozzle Size Selection Chart Determine the nozzle size by the pressure washer’s GPM @ PSI (gallons per minute @ a specific pounds per square inch). If the nozzle size is too small, your equipment can be damaged. If the nozzle size is too large, cleaning ability is compromised. Nozzle fan degree does not effect nozzle size selection.

Standard nozzle degrees — 0°, 15°, 25°, and 40°. Using the wrong nozzle degree can damage the surface you are cleaning. 0° – Red: 15° – Yellow: 25° – Green: 40° – White: ! Cutting nozzle. It delivers a concentrated stream that can gouge or cut. It can cut stub born stains from concrete and other hard surfaces. ! Chiseling nozzle Working at a 45° angle, this nozzle works like a scraper, stripping paint, grease and grime from hard surfaces. ! Flushing nozzle. The most commonly used nozzle for cleaning dirt from siding, sidewalks and metal furniture as well as for wet sweeping leaves. !Wash nozzle. Its wide spray allows you to wash and rinse a large area fast. It is usually safe with most surfaces, including aluminum siding, windows and vehicles. Page 78 Gallons Per Minute - GPM
