Cleaning and Applying Detergent

IMPORTANT: Use detergents designed specifically for pressure washers. Household detergents could damage the pump.

CAUTION

You must attach all hoses before you start the engine.

•Starting the engine without all the hoses connected and without the water turned ON will damage the pump.

•Damage to equipment resulting from failure to follow this instruction will void warranty.

To apply detergent follow these steps:

1.Review ProjectPro™ nozzle use.

2.Prepare detergent solution as required by manufacturer.

3.Place small filter end of detergent siphoning tube into detergent container.

CAUTION

Keep the chemical injection tube from coming in contact with the hot muffler.

•When inserting the filter into a detergent solution bottle, route the tube so as to keep it from inadvertently contacting the hot muffler.

4.Make sure black ProjectPro™ cleaning detergent nozzle is installed.

NOTE: Detergent cannot be applied with the high pressure nozzles (Yellow, Orange or Red).

5.Make sure garden hose is connected to water inlet. Check that high pressure hose is connected to spray gun and pump and start engine.

6.Apply detergent to a dry surface, starting at lower portion of area to be washed and work upward, using long, even, overlapping strokes.

7.Allow detergent to soak in between 3–5 minutes before washing and rinsing. Reapply as needed to prevent surface from drying. DO NOT allow detergent to dry on (prevents streaking).

IMPORTANT:You must flush the chemical injection system after each use by placing the filter into a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.

Pressure Washer Rinsing

For Rinsing:

1.Apply trigger lock to spray gun.

2.Remove black cleaning detergent nozzle from nozzle extension.

3.Select and install desired high pressure nozzle following instructions “How to Use ProjectPro™ Nozzle System”.

4.Keep spray gun a safe distance from the area you plan to spray.

WARNING

High pressure spray could cause you to fall if you are too close to the cleaning surface.

•Keep spray nozzle between 8 to 24 inches away from cleaning surface.

•Operate this unit on a stable surface.

•Be extremely careful if you must use the pressure washer from a ladder, scaffolding or any other relatively unstable location.

•Firmly grasp spray gun with both hands when using high pressure spray to avoid injury if gun kicks back.

5.Apply a high pressure spray to a small area and then check the surface for damage. If no damage is found, you can assume it is okay to continue rinsing.

6.Start at top of area to be rinsed, working down with same overlapping strokes as you used for cleaning.

Cleaning Detergent Siphoning Tube

If you used the detergent siphoning tube, you must flush it with clean water before stopping the engine.

1.Place chemical injection siphon/filter in a bucket full of clean water.

2.Attach black cleaning detergent nozzle.

3.Flush for 1-2 minutes.

4.Shut off engine.

IMPORTANT: Simply shutting OFF engine will not release pressure in the system. When the engine has shut down, squeeze the trigger on the spray gun to relieve the pressure in the hose.

Automatic Cool Down System

(Thermal Relief)

If you run the engine on your pressure washer for

3-5 minutes without pressing the trigger on the spray gun, circulating water in the pump can reach temperatures above 125°F.The system engages to cool the pump by discharging the warm water onto the ground.
