NOZZLE TYPE

• The red 0 degree tip provides a straight line of spray. It provides the highest amount of pressure. It is best used for removing hard, stuck-on grime or dirt.

| Green – Narrow fan tip (25° )

• The green pressure washer tip pro- vides high versatility with its 25 degree angle tip. Referred to as the washing tip, because it provides adequate pressure to remove dirt from surfaces, but is designed to not dam- age many surfaces. This pressure washer tip is designed for “sweeping” foliage or debris given its wide angle. This tip is versatile due to its wide area of cleaning and strong pressure application.

| White – Wide fan tip (40° )

• The white 40 degree tip, referred to as the “fan” tip creates the widest area of cleaning with relatively low pressure. This pressure washer tip is best used for light or delicate cleaning applications. It is recommended for light cleaning on wood decks and other soft or delicate surfaces.

| Black – Soap spray tip

• The black soap spray tip, is used for soap application. Soap is applied un- der low pressure high volume for optimum performance. Soap cannot be applied under high pressure with this machine.

| Turbo Nozzle Tip

• The nozzle rotates in a zero to 15 degree spray pattern in a circular motion to break down tough dirt and grime. The spray pattern can cover area of 4 to 8 inches wide, depending on a distance between the tip and the surface being cleaned.
