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 2mm
or 5/64 allen wrench (like the one included in the kit).

a small paper clip to free the foreign materials clogging
or restricting the nozzle..
