NOZZLE MAINTENANCE
If the nozzle becomes restrictedor clogged with foreign materials, such as dirt, excessive pump pressure may develop. A partially clogged nozzle can cause a pulsing sensation during use. This generally is not a pump
related problem, but rather a clogged or partially restricted nozzle.
If the nozzle becomes clogged or partially restricted, immediately clean the nozzle with the kit included with your pressure washer by following these instructions:
Reinstall orifice into nozzle. DO NOT overtighten.
o Reconnect nozzle to nozzle extension.
•Reconnect the water supply, turn ON the water, and start the engine.
-Test the pressure washer by operating with nozzle in the high and the tow pressure positions.
