Applying Detergent with the Adjustable Nozzle

IMPORTANT: Use soaps 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 use of adjustable nozzles.

2.Prepare detergent solution as required by job.

3.Place filter end of chemical injection hose 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.Slide adjustable nozzle forward to low pressure mode. Detergent cannot be applied with nozzle in high pressure position.

5.Make sure garden hose is connected to water inlet. Check that high pressure hose is connected to spray gun and pump. 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" for 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.Slide nozzle backward to high pressure, press trigger and wait for detergent to clear.

NOTE: You can also stop detergent from flowing by simply removing chemical injection hose from bottle.

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

3.Apply a high pressure spray to a small area, then check the surface for damage. If no damage is found, it is okay to continue cleaning.

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.

4.Start at top of area to be rinsed, working down with same overlapping strokes as you used for washing and applying detergent.
