Distance From Cleaning Surface
The distance between the spray tip and the cleaning surface is another factor that affects the impact force of the water. The impact force of the water increases as the tip is moved closer to the surface.
How to Avoid Damaging Surfaces
Damage to cleaning surfaces occurs because the impact force of the water exceeds the durability of the surface. You can vary the impact force by controlling the spray tip angle to the cleaning surface and the distance from the cleaning surface and by changing the spray tip. NEVER use a narrow high impact stream on a surface that is susceptible to damage. Avoid spraying windows with a narrow high impact stream. Doing so may break the window. The most sure way to avoid damaging surfaces is to follow these steps:
1.Before triggering the gun, make sure the quick connect tip you are using is appropriate for the application.
2.Place the spray tip approximately
3.Vary the fan pattern spray angle and the distance to the cleaning surface until optimum cleaning efficiency is achieved without damaging the surface.
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).
uPW1625: Replace lance with Soap Dispenser. Add soap to bottle and reattach bottle to soap dispenser.
uPW1825 & PW1835: Pour soap into soap container. Adjust lance to Soap position (refer to page 7, “How do I get high pressure?”, for description of soap use)
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.Rinse with high pressure.
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.
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.
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.
6.When checking or repairing unit, remove the wall outlet plug from the wall.
7.Before overnight storage, long term storage, or transporting unit, disconnect the water supply.
Shutdown
1.Be sure all detergent is flushed from system.
2.Turn the motor OFF.
3 Turn the water supply OFF.
4.After the motor and water supply are turned off, trigger the gun to depressurize the system.
