noted from the detergent, do not use it when cleaning.

2.First, pass over the area with a light cleaning, and then more thoroughly clean it.

3a. For a vertical or sloped surface:

a. Wash from the top down.

b. 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:

a. If a thin layer of water accumulates on the surface, periodically use the stream to direct this water towards the drainage.

b. After the major cleaning is done, sweep the surface with the stream to help direct loose debris toward the drainage.

4.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.

5.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.

6.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.

7.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.
