The chemical or detergent is siphoned into the pump outlet and is mixed during
spraying. Only use the soap pressure nozzle (black) as it is designed for mixing
the solutions.
1. Prepare the chemical or detergent per the instructions with the product.
2. Press the open end of the siphon hose onto
barbed detergent injector fitting (B) located
on the pump outlet (Fig. 17-1).
3. Press the siphon hose with the filter
attachment into the container holding
chemical or detergent. Make sure the filter is
fully submerged in the solution to avoid
drawing air into the system.
4. Install the soap pressure nozzle (black).
5. Start the pressure washer as instructed in this manual and the Engine manual.
6. Spray the solution following the instructions in the Spraying section.
7. Apply solution to a dry surface, starting at the lower portion of area to be
washed and work upward, using long, even, overlapping strokes.
a. Allow detergent to soak in for 3 to 5 minutes before washing and rinsing.
Reapply as needed to prevent the surface from drying. DO NOT allow
detergent to dry on (prevents streaking).
b. Consult the chemical instructions to determine if it should be rinsed off
and the time needed to soak before rinsing.
8. Clean the pressure washer after using chemicals or detergents by placing the
filter end of the siphon hose in a container of clean water. Turn on the pressure
washer at low pressure and spray to draw clean water through the system to
flush it out. This will take 1 to 2 minutes.
