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
- 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 ON/OFF valve should be closed while performing this, to insure you do not lose any solution. Periodically take the screen at this location out and clean it.
- 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 water & a good quality brand of dishsoap. 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

Troubleshooting the 2.1 g.p.m. Pump:
- Check inline fuse on the wires on the pump. If blown, replace with new fuse.
- 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.
runs after doing this, you will know that your lead wire assembly needs to be replaced.
- Make sure the bypass line valve is closed, to allow the pressure to build up in your system.

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.
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 FIMCO
Tank Neutralizer and Cleaner, and repeat cleaning instructions
above.
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.
