Pressure Washers

Operation (Continued)

1.Before triggering the gun, adjust the nozzle or quick connect tip to a wide fan pattern.

2.Place the nozzle approximately 4-5 feet away from the cleaning surface. Then hold the nozzle at a 45 degree angle to the cleaning surface. Trigger the gun.

3.Vary the fan pattern spray angle and the distance to the cleaning surface until optimum cleaning efficiency is achieved without damaging the sur- face.

TURBO NOZZLE (NOT INCLUDED WITH ALL MODELS)

A turbo nozzle, sometimes referred to as a rotary nozzle, can significantly reduce cleaning time. The turbo nozzle combines the power of a narrow high impact stream with the efficiency of a 25 degree fan pattern. The turbo nozzle swirls a narrow high impact stream into a cone shape to clean a larger area.

Since a turbo nozzle NOTICE uses a narrow high

impact stream, only use a turbo lance in applications where the cleaning surface cannot be damaged by narrow high impact spray. The turbo nozzle is NOT adjustable and cannot be used to apply detergent.

4. Detergent Application

USE THE INSTRUCTIONS APPROPRIATE FOR MODEL PURCHASED

NOTE: Use only detergents formulated for pressure washers.

NOTE: Test detergent in an inconspicuous area before use.

Never slide the

NOTICE nozzle from low to high pressure or from high to low pressure when the gun is triggered.

and prevent the application of the deter- gent.

Once applied to a cleaning surface, detergents take time to break down dirt and grime. Detergents work best when applied at low pressure.

You can effectively clean surfaces by combining the chemical action of detergents with high pressure rinses. On vertical sur- faces, apply the detergent starting at the bottom and work your way upward. This method prevents the detergent from sliding down and causing streaks. Begin high pressure rinsing at the bottom and work your way upward. On particularly tough stains, use a brush in combination with detergents and high pressure rinsing.

1.Follow manufacturer’s label direc- tions for mixing correct concentra- tions of soap/detergents. The soap detergent to water ratio through the pump is approximately 10% (1 to 10).

2.Insert the filter end of the clear plas- tic detergent tube into the deter- gent container.

3a. Place hand around the 3.5” spraying end section of the lance (the section

that turns from left to right). Pull firmly and quickly away from you. (NOTE: Do not adjust lance while spraying.) The lance will extend 1/2” and be in low pressure (See Figure 18). Soap can only be drawn in low pressure.

3b. For units with quick connect tips: use the black 65o quick connect spray tip (See Figure 16).

4.If equipped, adjust the detergent injection flow by turning the collar of the injector. Turning collar clock- wise decreases flow of detergent and turning collar counter clock- wise increases detergent flow (See Figure 17).

GENERAL CLEANING TIPS

1.Apply the detergent so that it thor- oughly covers the cleaning surface. Apply the detergent from bottom to top to prevent the detergent from

DETERGENTS

The use of detergents can dramatically reduce cleaning time and assist in the removal of difficult stains. Many detergents are customized for pressure washer use on specific cleaning tasks. Pressure washer detergents are as thick as water. Using thicker detergents – like dish soap – will clog the chemical injection system
