Nozzle Maintenance_________________
If the adjustable 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 the adjustable nozzle becomes clogged or partially
restricted, immediately 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 nozzle extension from the spray gun.
• Adjust the nozzle extension to the stream position.
• Remove the nozzle from the end of the nozzle extension
(Figure 21) using a 2mm or 5/64 alien wrench (like the
one included in the kit).
