Assembly

Your sprayer has been mostly assembled at the factory. The
only requirement will be for you to hook up your battery
leads to a fully charged 12 Volt battery. The red wire must
be connected to the "hot" lead, and the black wire should be
connected to the ground.

Operation

General Information

Thank you for purchasing this product. The purpose of this
manual is to assist you in operating and maintaining your lawn
& garden spot sprayer. Please read it carefully, as it furnishes
information which will help you achieve years of trouble-free
operation.

Warranty/Parts/Service

Products are warranted for one year from date of purchase
against manufacturer or workmanship defects.

Commercial users have a 90 day warranty.

Your authorized dealer is the best source of replacement parts
and service. To obtain prompt, efficient service, always
remember to give the following information...

Your sprayer is equipped with (2) ON/OFF switches. One is
on the wire assembly that you hook up to your battery, the
other is on the pump itself, on the opposite end of the
pressure switch. The "-" is the "ON" position and the "o" is
the "OFF" position for the switches. Make sure both
switches are depressed in the "-" position for operation.

In addition to the ON/OFF switch, the pump is equipped with
an electronic pressure switch that is factory pre-set for it to
shut off at 60 p.s.i.. This switch assembly is the 'square box'
on the head portion of the pump.

Always fill the tank with a desired amount of water first, and
then add the chemical slowly, mixing as you pour the
chemical into the tank. You may use the handgun to spray
into the solution in order to mix the chemical and water.

Initially begin spraying by opening the handgun. This will
enable the air in the line to be purged through the handgun
tip, while building pressure.

The pumping system draws solution from the tank, through
the strainer/filter, and to the pump. The pump forces the
solution under pressure to the handgun and/or boom
nozzles.

Open the handgun by squeezing the handle lever.

•

Rotating the adjustable nozzle tip on the handgun will

•
change the tip pattern from a straight stream to a cone
pattern (finer mist).

Testing the Sprayer

NOTE:

It is VERY important for you to test your sprayer with plain
water before actual spraying is attempted. This will enable
you to check the sprayer for leaks, without the possibility
of losing any expensive chemicals.

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 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.

*** IMPORTANT REMINDER ***

A

This unit comes with an On/Off (shut-off)
valve located at the inlet location of the
tank, towards the underside. (See Detail A).
You must make sure the valve is in the
"open" position before using your unit.

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 2.1 g.p.m. Pump:

Pump will NOT run:

- 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.

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 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.

- Make sure the bypass line valve is closed, to allow the pressure to build up in your system.

- 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
and test.
