4.3.1 NOZZLE TYPE

SPRAY TIP	APPLICATION
	Green – Narrow fan tip (25° ) •   The green pressure washer tip pro- vides high versatility with its 25 de- gree angle tip. Referred to as the washing tip, because it provides adequate pressure to remove dirt from surfaces, but is designed to not damage 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 de- gree spray pattern in a circular motion to break down tough dirt and grime. The spray pattern can cover an area of 4 to 8 inches wide, depending on the distance between the tip and the surface being cleaned.

4.3.2 INSTALL THE NOZZLE

1. Pull back the quick-connect collar on the spray wand (2).
2. Install the nozzle (20) onto the spray wand (2).
3. Release the quick-connect collar to attach the nozzle (20).

4.4 ADD DETERGENT

WARNING
Do not use household detergents, acids, alkalines, bleaches, solvents, flammable material, or industrial-grade solutions, which can do damage to the pump.
WARNING
Do the instructions on the solution bottle to prepare detergent.
NOTE
If it is necessary, use a funnel to prevent the spill of detergent. Clean and dry the spilled detergent when you fill it.
NOTE
Soap/detergent can only be applied with this machine when the black nozzle(75 degrees) is installed.

1. Put the machine vertically on a flat surface..
2. Open the cap on the detergent tank (13).
3. Put the detergent into the detergent tank (13).
