STORAGE
PRESSURE WASHER PUyP
Water should not remain in the unit for long periods of time.
Sediments of minerals can deposit on pump parts and
"freeze” pump action. After each time you are finished using
your pressure washer, follow this procedure:
o Flush detergent hose by placing the injector filter into
a pail of clear water while running Pressure Washer
with nozzle in low pressure mode. Flush until you can
see clear water flowing through hose.
o Shut off the pressure washer, unplug it and let it cool,
THEN REMOVE ALL HOSES,
o Store the pressure washer and its components in such
a way as to protect it from freezing.
o Store in a dean, dry area. Ideally, the unit should be
stored in a frost-free room.
e 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
and use it. Replace the hose with the genuine Crafts­
man part.
o Drain water from hose and properly store it to prevent
cuts and general wear.
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.
o Disconnect the power supply and turn off the water
supply.
o Separate the wand from the gun,
a Remove the nozzle from the end of the wand using a
2mm or 5/64 alien wrench.
o Use a piece of wire or small paper clip to free the foreign
materials (Fig. 14) from clogging or restricting the noz­
zle,
a Use your water supply to back flush the wand removing
additional debris. Back flush for 30 seconds to 1 minute
(Fig, 15} Turn wand to stream spray position and move
from low to high pressure while flushing,
a Reinstall the nozzle into the wand, do not over tighten,
a Reconnect wand to the gun.
o Reconnect the water supply and turn on the water,
a Reconnect the electrical power supply.
Test the pressure washer by operating in the high and low
position.
Insert wire into nozzle and turn back and forth to dear
obstruction.
