Nozzle Maintenance

If a nozzle becomes restricted or clogged with foreign materials, such as dirt, excessive pump pressure may develop. A pulsing sensation occurs during use. This generally is not a pump related problem, but rather a clogged or partially restricted nozzle.

If a nozzle become clogged or partially restricted, immediately clean it with the kit included with your pressure washer by following these instructions:

•Shut off the engine and turn off the water supply.

•Remove the nozzle from the end of the nozzle extension.

•Use the wire included in the kit or a small paper clip to free the foreign materials clogging or restricting the nozzle (Figure 14).

•Reinstall the nozzle into the nozzle extension.

•Reconnect the water supply, turn on the water, and start the engine.

•Test the pressure washer.
