Do not turn the cleaner over when it is pressurized by connection to an operating pressure washer
to avoid high-pressure spraying water that could cause serious personal injury.
If the surface cleaner's rotating arm is not spinning, ensure that the cleaner is not pressurized then tilt
it upward so you can see the underside of the deck. If a nozzle is not spraying, it's plugged and needs
to be cleaned. The best way to unclog a plug is to remove the nozzle (9/16" wrench) and tap it on a
hard surface (being careful not to damage the threads). It may be necessary to unclog the nozzle by
running a thin wire through the tip.
Seal the threads before replacing the nozzle. Teflon tape can often clog a nozzle so be sure tape
does not get into the nozzle flow path. A light duty liquid or paste thread sealant is the best way to
seal the threads (photo).
