Cleaning Nozzles; Maintenance - Craftsman 480.991170 Instrucciones De Uso

How to Avoid Damaging Surfaces
• Damage to surfaces being cleaned occurs because the impact
force of the water pressure exceeds the durability of the sur-
face. Bare wood can be penetrated; paint can be peeled off, etc.
You can vary the force of the power washer by controlling:
1. The angle of the surface being cleaned.
2. The distance of the nozzle from the surface being cleaned.
• Never use a narrow high pressure stream of water on soft
surfaces susceptible to damage.
• Use the 25˚ angle quick connect nozzle when cleaning windows.
Be sure to place the nozzle approximately four to five feet away
from the window with the nozzle at forty five degree angle.
Squeeze the trigger and vary the spray pattern and angle until
optimum cleaning efficiency is achieved.
Using Power Cord
• Easily remove the power cord from the unit by swiveling the
cord hook to the right or left. The power cord then can be easily
slid off to either side of the power washer unit.
• Swivel cord hook back to center when ready to wrap the cord
back into place for storage.

MAINTENANCE

Detergents
• Use detergents designed for power washers. Hardware stores or
home centers also have power washer detergents for different
cleaning projects. The cleaning solution should be the consis-
tency of water in order to prevent clogging your detergent bottle
and nozzle.
• This system applies detergent under low pressure. The
cleaning power of the detergents is enhanced when applied
with low pressure and enough time is given to break down
dirt and grime. Detergent can only be applied and siphoned
in low pressure mode using the soap nozzle. The
combination of low pressure and chemical action is very
effective and can be better than scrubbing if applied
properly. Always spray detergent on a dry surface. Do not
pre-soak area. Wetting the surface first dilutes the deter-
gent and reduces its cleaning ability. Do not allow detergent
to dry on surface. On vertical surfaces being cleaned, apply
detergent to lower surfaces and work your way up to pre-
vent detergent from causing streaks in the dirt and grime.
Rinse detergent by pressure washing from bottom up for
same reason.
• If a stain is particularly tough, it may be necessary to
reapply the detergent and use a bristled brush to scrub the
stain. Subsequent power washing after brushing should
successfully complete your cleaning job.
Cleaning Garden Hose Adapter
• The screen inside the adapter should be cleaned periodically.
Remove it by dragging a thumb over the screen with enough
pressure to pull the screen and washer out. Rinse it with clean
water and then place it back in the adapter.

Cleaning Nozzles

• A clogged or partially clogged nozzle can cause significant
reduction of water pressure coming out of the nozzle and/or
cause the unit to pulsate while spraying.
• Turn off the unit.
• Turn off the water supply to the unit.
• Relieve any pressure trapped in the hose by squeezing the
trigger 2-3 times, and then lock the spray gun by turning the
dial to lock (either 3 or 9 o'clock position).
