NOZZLE MAINTENANCE
If the nozzle becomes restricted or clogged with for-
eign 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 par-
tially restricted nozzle.
If the 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 washer and turn off the water supply.
Separate the nozzle extension from the gun.
Open the adjustable nozzle to the narrow stream
setting.
Remove the nozzle using the allen wrench provided
in the kit.
Use the wire included in the kit (Figure 11) or a
small paper clip to free the foreign materials clog-
ging or restricting the nozzle.
Remove additional debris by back flushing water
supply through wand (Figure 12). Back flush
between 30 to 60 seconds. Turn wand to stream
spray while flushing.
Reinstall the nozzle. Do not overtighten.
Reconnect the wand to the gun.
Reconnect the water supply, turn on the water, and
start the washer.
Test the pressure washer by operating with nozzle
in narrow and expanded streams.
PREPARING THE UNIT FOR
STORAGE
Water should not remain in the unit for long periods of
time. Sediments of minerals can deposit on pump
parts and freeze pump action. If you do not plan to
use the Pressure Washer for more than 30 days,
follow this procedure:
1. Shut off the pressure washer, unplug it and let it
cool,
then remove all hoses.
2. Store the pressure washer and its components in
such a way as to protect it from freezing.
5. Store in a clean, dry area. Ideally, the unit should
be stored in a frost-free room.
6. Coil the high pressure hose and inspect it for
damage. Cuts in the hose or fraying of it could result
in leaks and loss of pressure. Should any damage be
found, replace the hose.
DO NOT
attempt to repair a
damaged hose. Replace the hose with the genuine
Generac part.
7. Drain water from hose and properly store it to pre-
vent cuts and general wear.
