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.
Troubleshooting the Pump:
Pump will NOT run:
- Check inline fuse on the wires on the pump.
- Make sure on/off switch is in the 'on' position (-).
- Make sure you 12 volt source (battery) is fully charged.
- Insure a tight connection at the battery clips.
If none of the above will work, try pulling the wires off the
pressure switch, and short them out. If your pump runs
when you do this, you know you will need to replace
your pressure switch.
Pump runs, but does not prime:
- Check line strainer (screen) in the tank, connected to
the bottom of the intake tube. Periodically take the
screen at this location out and clean it.
- Make sure the bypass line valve is closed, to allow the
pressure to build up in your system. (If equipped with
bypass)
- Unscrew the head portion of your pump and remove
the check valve assembly from inside. You need to
make sure the O-Ring comes out with this piece as well.
(See the exploded view to help identify these
components) These pieces can be cleaned which, in
most cases, will help restore some, if not most, of your
prime. Soak this check valve in a solution of hot, soapy
water. A good name-brand dishsoap works well for this.
A little bit of 'scrubbing' with perhaps an old toothbrush
may be required to actually break up any build-up that
may be on the check valve. Rinse off the pieces and
replace them back into your pump. Reassemble the
pump. Hook it back up and test.
