After Spraying
After use, fill the sprayer tank part way with water. Start the
sprayer, and allow the clear water to be pumped through
the plumbing system and out through the spray nozzles.
Refill the tank about half full with plain water and use a
chemical neutralizer, such as 'Nutra-Sol', or equivalent,
and repeat cleaning instructions above. A mix of water and
some good dish detergent, would be a sufficient
alternative.
Flush the entire sprayer with the neutralizing/cleaning
agent, then flush out one more time with plain water.
Follow the chemical manufacturer's disposal instructions of
all wash or rinsing water.
For the boom, (if applicable) remove the tips and screens
from the nozzle assemblies. Wash these items out
thoroughly. Blow the orifice clean and dry. If the orifice
remains clogged, clean it with a fine bristle (NOT WIRE)
brush, or with a toothpick. Do not damage the orifice.
Water rinse and dry the tips before storing.
WARNING: Some chemicals will damage the pump
valves if allowed to soak untreated for a length of time!
ALWAYS flush the pump as instructed after each use.
Winter Storage
Drain all water out of your sprayer, paying special
attention to the pump, handgun, and valve(s). These items
are especially prone to damage from chemicals and
freezing weather.
The sprayer should be winterized before storage by
pumping a solution of RV antifreeze through the entire
plumbing system. This antifreeze solution should remain in
the plumbing system during the winter months. When
spring time comes and you are preparing your sprayer for
the spray season, rinse the entire plumbing system out,
clearing the lines of the antifreeze solution. Proper care
and maintenance will prolong the life of your sprayer.
