an inconspicuous area before use.
DETERGENTS
The use of detergents can dramatically
reduce cleaning time and assist in
the removal of difficult stains. Many
detergents are customized for pressure
washer use on specific cleaning tasks.
Pressure washer detergents are as thick
aswater.Usingthickerdetergents–
like dish soap – will clog the chemical
injection system and prevent the
application of the detergent.
Once applied to a cleaning surface,
detergents take time to break down
dirt and grime. Detergents work best
when applied at low pressure.
You can effectively clean surfaces by
combining the chemical action of
detergents with high pressure rinses. On
vertical surfaces, apply the detergent
starting at the bottom and work your
way upward. This method prevents
the detergent from sliding down and
causing streaks. Begin high pressure
rinsing at the bottom and work your
way upward. On particularly tough
stains, use a brush in combination with
detergents and high pressure rinsing.
1. Follow manufacturer’s label
directionsformixingcorrect
concentrations of soap/detergents.
The soap detergent to water ration
throughthepumpisapproximately
10% (1 to 10).
2. Insert the filter end of the clear
plastic detergent tube into the
detergent container.
3. UsetheBLACK 65° quick connect
spray tip.
4. Adjust the detergent injection flow
by turning the collar of the injector.
Turning collar clockwise increases
detergent flow.
GENERAL CLEANING TIPS
1. Apply the detergent so that it
thoroughly covers the cleaning
surface. Apply the detergent from
bottom to top to prevent the
detergent from sliding down and
streaking. Wait a couple of minutes
for the detergent to break down the
dirtandgrime.Useabrushtolightly
scrub heavily soiled areas. NEVER
allow the detergent to dry on the
cleaning surface.
Operating Instructions and Parts Manual
2. To rinse: replace black 65° spray tip
with another color tip.
NEVER replace
quick connect
tip when gun is triggered. Always
engage trigger lock on gun before
removing or installing quick
connect tips.
3. After using detergents, flush the
suction system by placing the
detergent suction tube into a bucket
of clean water and spraying with the
black spray tip.
5. CLEANING POWER
The easiest way to regulate the cleaning
power of your pressure washer is by
changing the distance from the surface
you are cleaning. Begin spraying with a
wide fan pattern while standing several
feet from the surface. Slowly move
closer to the object you are cleaning,
adjusting the spray pattern as necessary,
until you find the most effective
cleaning technique.
NOTE: The unit also has a pressure
adjustment knob on the pump that can
adjust the pressure.
6. FINAL RINSE
The final rinse should start at the
bottom and work upward. Make sure
that you thoroughly rinse the surface
and that you remove all detergent.
7. PRESSURE RELIEF PROCEDURE
To reduce the risk of bodily injury
or property damage, always follow
this procedure whenever spraying is
stopped, when work is completed, and
before checking or repairing any part of
the system.
1. Engage the trigger safety latch.
