4. Detergent Application

Note: Use only detergents formulated for pressure washers..Test detergent in an inconspicuous area before use..

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 and prevent the application of the detergent..

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 surfaces, 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 directions for mixing correct concentrations of soap/detergents.. The soap detergent to water ration through the pump is approximately

10% (1 to 10)..

2.Insert the filter end of the clear plastic detergent tube into the detergent container..

3.Use the black 65° quick connect spray tip..

4.Adjust the detergent injection flow by turning the collar of the injector.. Turning collar clockwise increases detergent flow..

General Cleaning Tips

1.Apply the detergent so that it thoroughly covers the cleaning surface.. Apply the detergent from bottom to top to prevent the detergent from sliding down and streaking.. Wait a couple of minutes for the detergent to break down the dirt and grime. Use a brush to lightly scrub heavily soiled areas.. Never allow the detergent to dry on the cleaning surface..

2.To rinse: replace black 65° spray tip with another color tip..

neVER replace quick connect

tip when gun is triggered. Always engage trigger lock on gun before removing or installing quick connect tips.

3.After using detergents, flush the suction system by placing the detergent suction tube into a bucket of clean water and spraying with the black spray tip..

5.Cleaning Power

The easiest way to regulate the cleaning power of your pressure washer is by changing the distance from the surface you are cleaning.. Begin spraying with a wide fan pattern while standing several feet from the surface.. Slowly move closer to the object you are cleaning, adjusting the spray pattern as necessary, until you find the most effective cleaning technique..

Note: The unit also has a pressure adjustment knob on the pump that can adjust the pressure..

6. Final Rinse

The final rinse should start at the bottom and work upward.. Make sure that you thoroughly rinse the surface and that you remove all detergent..

7. Pressure Relief Procedure

To reduce the risk of bodily injury or property damage, always follow this procedure whenever spraying is stopped, when work is completed, and before checking or repairing any part of the system..

1.. Engage the trigger safety latch..

2.Turn the unit off..

3.Shut off the water supply..

4.Disengage the trigger safety latch and trigger the gun to relieve pressure..

5.Re-engage the trigger safety latch..

6.When checking or repairing unit, remove the ignition cable from the spark plug..

7.Before overnight storage, long term storage, or transporting unit, disconnect the water supply and turn off the fuel supply valve..

8.Shutdown

1..Be sure all detergent is flushed from system..

2. Turn the engine OFF..

3 Turn the water supply OFF..

4.After the engine and water supply are turned off, trigger the gun to depressurize the system..

neVER turn the water supply off

before turning the engine/motor off. Serious damage could occur to the pump and/or engine/motor.

neVER disconnect the high pressure

discharge hose from the machine while the system is pressurized. To depressurize, turn engine/motor off, turn water supply off and squeeze gun trigger 2-3 times.

5.After each use, wipe all surfaces of the pressure washer with a clean, damp cloth..

9.Storage

•Do not store the pressure washer outdoors..

•Do not store the pressure washer where it might freeze unless it has been properly winterized..

long term storage instructions (more than 30 days in storage)

1..Remove fuel from the tank and run the pressure washer in a normal operating mode until the engine stops from a lack of fuel.. Normal operating mode means actually spraying water from the gun while the engine is running..

Alternate method – Add fuel stabilizer to gas in the tank and run in normal operating mode for at least five minutes..

2..Stop the engine, turn off the water supply, and trigger the gun to release pressure in the high-pressure hose..

3.Disconnect the water supply and high pressure hose from the pump..

4.Allow the engine to cool..

5.Disconnect the spark plug wire and remove the spark plug..

6.Pour 1/2 oz.. of engine oil into the spark plug hole..
