Pressure Filter Cleaning
There is an in-line pressure filter in the spray
pressure line that traps the minute particles that are
not collected by the main suction filters.
WARNING: Always wear the recommended
personal protective equipment and use caution
while working with chemicals.
Unscrew the filter body. It may be necessary to use
the pressure filter tool (GA4522610). Allow the
chemical in the filter to dribble out into a suitable
container to avoid environmental contamination and
avoid personal contact. Clean or replace the filter
screen with the same mesh size as necessary and
then refit the filter body.
Flushing
The following information is provided as a general
guide for flushing your sprayer following a spray
application.
For more specific information regarding flushing, and
decontamination, specific to the products that you
are applying, it is recommended that you consult the
chemical label or your chemical supplier.
To use the flush water tank to flush pump & boom
only:
1. Turn pump off.
2. Turn 3 way ball valve to draw from flush water
tank rather than main product tank.
3. Set Raven console into manual mode.
4. Switch all boom sections to ON.
5. Hold increase button for 15-20 secs. This will
ensure that fast close valve is fully open to direct
all flow to booms (This will eliminate bypass from
the booms to main tank).
6. Turn pump ON. The pump will now draw water
from the flush water tank and direct all flow to
the booms.
7. Keep boom switches on until the contents of the
flush water tank has been run through the booms.
NOTE: If the pressure gauge increases dramatically,
slow down pump RPM.
