Outdoor Cleaning with Pressure Washers

Spray Wand Maintenance

Step 1

Shut off the engine and turn off the water supply. Depress the spray-gun trigger to relieve the pressure in the system. Detach the wand from the spray gun. If you have an adjustable nozzle, twist the nozzle to STREAM, then remove the nozzle orifice using a 2mm (or 5/64) Allen wrench. If you have Quick-Connect spray tips, simply remove the spray tip from the nozzle.

Step 2

Use a paper clip to free any foreign material clogging or restricting the orifice or spray tip (inset). Note: Some manufacturers provide a wire nozzle-cleaning tool with the maintenance kit.

Step 3

Flush water through the nozzle for one minute to remove debris. For an adjustable nozzle, turn the nozzle to STREAM and move from low- to high-pressure mode while flushing. Reinstall the orifice into the adjustable nozzle (do not overtighten), or install the spray tip into the nozzle, then reconnect the wand to the spray gun and test to ensure the nozzle works properly.
