noted from the detergent, do not use
it when cleaning.
First, pass over the area with a light 2.
cleaning, and then more thoroughly
clean it.
3a. For a vertical or sloped surface:
Wash from the top down.a.
If possible, direct the stream in the b.
same direction as the slope towards
a draining area. This will enable
better drainage and therefore better
cleaning.
3b. For a at surface:
If a thin layer of water accumulates a.
on the surface, periodically use the
stream to direct this water towards
the drainage.
After the major cleaning is done, b.
sweep the surface with the stream to
help direct loose debris toward the
drainage.
If detergent is to be applied: Only 4.
use pressure washing detergent; oth-
er detergents will clog or damage the
pressure washer. Apply the deter-
gent at low pressure, by using the low
pressure setting of the Spray Wand.
Allow the detergent several minutes
to sit and soak into the work surface;
this will improve cleaning efciency.
Briey shut off the unit and turn the
Pressure Control Sleeve counter-
clockwise to switch to high pressure
mode and automatically shut off the
soap dispenser for rinsing. Rinse off
all detergent completely.
Hold the Water Gun at about a 45° 5.
angle and steadily sweep the stream
back and forth; if a severe, head-on
angle is used, dirt may imbed in the
surface being cleaned. Follow a
steady, consistent pace during clean-
ing; this will help prevent stripes or
discoloration afterwards. If streaking
or uneven cleaning is noted at the
end of a project, go over the edges of
the streaks with a wide fan pattern to
help blend these lighter areas in.
If several different surfaces are to be 6.
cleaned, be careful not to damage
any of the less solid surfaces while
trying to clean the harder ones. This
is especially a concern when cleaning
tile and grout, bricks and mortar, or
stones and mortar.
If wood is being cleaned, be careful 7.
not to damage it. Wood will usually
require resurfacing (Sanding) and re-
coat with a surface protectant (wood,
stain, varnish) after it has dried. Try
to avoid leaving water on a wooden
surface; doing so can harm the sur-
face.
