Cleaning and Applying Chemical

Snapper 3500 PSI Pressure Washer

After you have applied detergent, scour the surface and rinse it clean as follows:

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.

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

the pump.

To apply detergent follow these steps:

•Review the use of the nozzles.

•Prepare the detergent solution as required by the manufacturer.

•Place the chemical injection siphon/filter into the detergent container.

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

• Make sure the black nozzle is installed.

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

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

•Apply the detergent to a dry surface, starting at lower portion of area to be washed and work upward, using long, even, overlapping strokes. Do Not allow the detergent to dry on (prevents streaking).

•Allow the detergent to soak in between 3–5 minutes before washing and rinsing. Reapply as needed to prevent surface from drying.

•Apply safety latch to spray gun.

•Remove the black chemical nozzle from the nozzle extension.

•Select and install the desired high pressure nozzle following the instructions “How to Use the Nozzles” on page 9.

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

•Increase or decrease spray pressure by turning the pressure control knob counterclockwise or clockwise respectively (Figure 15). Use lower pressure to wash items such a as a car or boat. Use higher pressure to strip paint and degrease driveways.

•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 cleaning.

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

Pressure Washer Rinsing

WARNING! Be extremely careful if you must use the pressure washer from a ladder, scaffolding or any other relatively unstable location. Hose water pressure builds as you climb. When you press the trigger, the recoil from the initial spray can be very strong. The high pressure spray could cause you to fall if you are too close to the cleaning surface.

(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 a temperature between 140–145°F. At this temperature, the system engages and cools the pump by discharging the warm water onto the ground. This system prevents internal

damage to the pump.
