Cleaning Chemical Injector Hose.
If you have used the chemical injector hose you must
flush it with clean water before stopping the engine.
1.Flush for five minutes.
2.Shut off the pump.
3.Simply shutting OFF engine will not release pressure
in the system. When engine has shut down,
squeeze the trigger on the gun to relieve the pres-
sure in the hose.
Nozzle Maintenance
If the adjustable nozzle becomes restricted or
clogged with foreign materials, such as dirt, excessive
pump pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
adjustable 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 wand extension from the gun.
Adjust the wand extension to the stream position.
Remove nozzle from the end of the wand extension
(Figure 17) using a 2mm or 5/64 allen wrench (like
the one included in the kit).
Use the wire included in the kit (Figure 17) or a
small paper clip to free the foreign materials clog-
ging or restricting the nozzle.
Figure 17 — Removing and cleaning nozzle.
Remove additional debris by back flushing water
supply through wand extension (Figure 18). Back
flush between 30 to 60 seconds. Turn wand exten-
sion to stream spray and move nozzle from low to
high while flushing.
Figure 18 — Backflushing the nozzle.
Reinstall nozzle into the wand extension. DO NOT
over tighten.
Reconnect the wand extension to the gun.
Reconnect the water supply, turn on the water, and
start the engine.
Test the pressure washer by operating with nozzle
in the high and in the low position.
