Cleaning
Filters
The fluid in the Sprayer is continually being
filtered through a screen filter in the boom
control feed line, agitation, and boom feed
lines. The Sprayer must have clean water to
prevent clogging of the screens and inline
check valves when in use.
At the start of each day before the water and
chemicals are added, the screens should be
checked. These screens must be cleaned
daily or more often as required. To clean,
follow this procedure:
1.
If there is water or solution in the
sprayer, close valves as needed to
isolate the filters.
2.
Loosen the filter bodies by hand. Do
not use a wrench as this could
damage the filter body.
3.
Remove the screens and inspect
them for dirt.
4.
Clean them using clean water.
5.
Inspect for holes or tears. If there is
damage, replace it.
6.
Install the screens and body to the
filter heads and tighten by hand.
IMPORTANT: Do not use a wrench as
this might damage the body. Do not
over tighten and crack the head.
7.
Open the ball valves to allow the
solution to circulate.
8.
Drain all screens before storage to
avoid freezing.
