Operating tips
Become Familiar With your machine:
1. Before beginning work, set aside enough time to
familiarize yourself with this machine’s cleaning
rate and capacity along with all instructions
and precautions contained in this section,
along with the Operating Instruction and
Controls and Features sections.
2. This unit is intended for various light to moderate
cleaning applications. If deeper cleaning is desired, it
can be attained at times, however this is done at the
expense of speed. This unit is not intended for paint
stripping or deep concrete cleaning applications.
3. Clean a test area to satisfaction before
proceeding with the entire area, as stated
in Cleaning Recommendations.
4. This unit has several settings and adjustments
that effect the speed of cleaning and the
water force applied to cleaning. Good
guidelines to keep in mind are:
WiDE StREam =
QuickER cOVERaGE But
liGhtER clEaninG.
naRROW StREam =
DEEpER clEaninG But
SlOWER cOVERaGE.
cleaning Recommendations
5. Clean an inconspicuous test area first. Always begin
with the fan spray at a distance of about 3-5 feet from
the surface being cleaned to avoid damaging it. Clear
the test area of people and water-sensitive objects.
If a pressure washing detergent is to be used, apply
the detergent to this area as well. After cleaning this
area, switch off the pressure washer and inspect
the area carefully for any damage or discoloration.
If any damage is noted from the pressure setting,
use a lighter setting when cleaning the rest of the
area. If damage or discoloration is noted from
the detergent, do not use it when cleaning.
6. First, pass over the area with a light cleaning,
and then more thoroughly clean it.
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.
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.
7. If detergent is to be applied: Only use pressure
washing detergent in the soap dispenser; other
detergents will clog the dispenser. Do not add
detergent to the body of the pressure washer.
Spray the surface with detergent until evenly
covered, then turn off the machine and water
source, release pressure, and remove the soap
dispenser. Allow the detergent several minutes to
sit and soak into the work surface; this will improve
cleaning efficiency. Turn on the water source and
power, and rinse off all detergent completely.
8. Hold the Spray 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 cleaning; 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.
9. 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.
10. If wood is being cleaned, be careful to avoid damage.
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 surface.
