NOZZLE MAINTENANCE

If the nozzle becomes restricted or 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, imme- diately clean the nozzle with the kit included with your pressure washer by following these instructions:

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

=Separate the wand from the gun.

,,Remove nozzle from the end of the wand using a 2ram or 5/64 allen wrench (like the one included in the kit).

Use the wire included in the kit (Fig. 29) or a small paper clip to free the foreign materials clogging or restricting the nozzle.
