Conditions of weather and terrain must be considered when
setting the sprayer. Do not spray on windy days. Protective
clothing must be worn in some cases.
Be sure to read the chemical label(s) correctly!
After testing, add water and chemical to the tank. Adjust the
pressure and spray as you did in the testing procedure.
Troubleshooting a 1.0 g.p.m. Pump:
Pump will NOT run:
- Check inline fuse on the wires on the pump. If blown,
replace with new fuse. (5 Amp mini-blade fuse...#5157204)
- Make sure BOTH on/off switches are 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 wire terminal "A" off
of the spade terminal of the pressure switch, and cross it
over and touch terminal "B". (You will need to remove the
pressure switch cap before doing this) If your pump runs
when you do this, you know you will need to replace your
pressure switch.
Another thing you can try is to take apart the switch box on
the lead wire assembly (#5274443) with the (2) phillips head
screws, and 'hot-wire' it together. Take the (2) wires that are
screwed to the rocker switch, off of the switch and twist
them together. This will insure you are getting the full 12
volts to the pump. If your pump runs after doing this, you will
know that your lead wire assembly needs to be replaced.
Pump runs, but does not prime:
- Check line strainer (screen) at the inlet location, at the
tank. You will need to unscrew the knurled nut to access
this screen. (see exploded view later in this manual) The
tank should be empty while performing this, otherwise you
may need to tilt the tank backwards a little bit so any
solution in the tank will be away from this inlet location.
Periodically take the screen at this location out and clean it.
- Unscrew (2) screws "S". This will allow you to inspect the
bearing and counterweight.
- Both the counterweight and the bearing need to spin
freely, and they both need to spin INDEPENDENT of each
other. If these 2 pieces are 'stuck' together, you will need to
break them free with some WD-40 or somthing similar and
this should restore most of your prime.

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 detergent, such as
'Dawn' dish soap 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.
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 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.
