noted from the detergent, do not use

it when cleaning.
First, pass over the area with a light

cleaning, and then more thoroughly

clean it.

3a.

For a vertical or sloped surface:

Wash from the top down.

If possible, direct the stream in the

same direction as the slope towards

a draining area. This will enable

better drainage and therefore better

cleaning.

3b.

For a flat surface:

If a thin layer of water accumulates

on the surface, periodically use the

stream to direct this water towards

the drainage.
After the major cleaning is done,

sweep the surface with the stream to

help direct loose debris toward the

drainage.

If detergent is to be applied: Only

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 efficiency.

Briefly 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°

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

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

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.
