Your Bestway Ag dealer is the best source for parts
and service. Always remember to give the following
information:

• Model number/serial number
Part descriptions and part numbers are found in
this manual for your convenience. Whenever you
need parts or repair service, contact your dealer
first. For warranty work, always present your sales
receipt, or other evidence of original purchase date.
ASSEMBLY
You will need to connect a 12-volt power source.
The red wire should be connected to the ‘hot’ or
positive terminal and the black to the negative, or
ground. The wiring harness will be found inside the
tank from the factory.
Some models include a pressure gauge, which you
will need to ax by screwing into place. Use of
thread sealer is recommended.
OPERATION
Your sprayer may be equipped with up to two (2)
power switches. One will be located on the wiring
harness and the other (if present) on the pump.
For two switch systems, please be sure both are
switched on for operation.
Always fill the tank with a desired amount of water
first, then add chemical slowly, mixing as you pour.
You may use the handgun to spray into the solution
to ensure proper mix.
Initially, begin spraying by opening the wand/
handgun. This will purge any air trapped in the line
through the tip, while building pressure.
The pump system draws solution from the tank,
through the strainer/filter and to the pump. It is
then forced to the wand/handgun and/or boom
nozzles.
• Open the wand/handgun by squeezing the
handle lever.
• Rotating the adjustable nozzle tip (if equipped)
on the wand/handgun will change the spray
pattern from a straight stream to a finer mist
(cone shaped pattern).

DATE OF PURCHASE:

POST SPRAY
After use, fill the tank partially with water. Start
the sprayer and allow clear water to be pumped
through the system and through the spray nozzles.
Refill the tank about halfway with water and use a
chemical neutralizer, such as “Nutra-Sol”, or equiv-
alent, and repeat cleaning process above. A mixture
of water and detergent, such as “Dawn” dish soap
can be used as an alternative.
Once complete, flush system with plain water an
additional time. Follow the chemical manufactur-
er’s disposal instructions.
If you have added a boom system to your sprayer,
remove the tips and screens from the nozzle assem-
blies. Rinse these out thoroughly.
Blow the orifice clean and dry. If it remains clogged,
use a fine bristle (NOT WIRE) brush. Take care not
to damage the orifice.
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.
WINTERIZATION/LONG TERM STORAGE
Drain all water from sprayer, with special attention
to the pump, wand/gun and valve(s).
Pump a solution of RV antifreeze through the sys-
tem. This solution should remain in the plumbing
system until ready for next use.
When ready to use again, rinse the entire system,
clearing the lines of the solution.
TROUBLESHOOTING
PUMP WILL NOT RUN:
• Check in-line fuse (if applicable)
• Make sure switches are in ‘on’ position
• Make sure battery is fully charged
• Check battery connection
If none of the above work, pull the wires off the
pressure switch and short them out. If pump runs,
the pressure switch needs to be replaced.
PUMP RUNS, BUT DOES NOT PRIME:
• Check strainer in tank and clean, if necessary
• Check that bypass valve is closed (if equipped)
• Clean the check valve assembly.
Unscrew the head portion of the pump and re-
move the check valve assembly from the inside.
Be sure to remove the O-ring as well. Clean these
pieces with hot, soapy water. You may want to soak
the valve, as well as scrub it with a toothbrush.
Rinse the pieces and reassemble for test.
WARNING
DO NOT USE PUMP IN AN EXPLOSIVE ENVIRONMENT.
DO NOT USE TO PUMP FLAMMABLE FLUIDS, INCLUDING
GASOLINE, KEROSENE, OIL, ETC.
CAUTION
PUMP PRESSURE SWITCH IS PRESET AT THE FACTORY. IMPROPER
ADJUSTMENT MAY CAUSE SEVERE OVERLOAD OR EARLY FAILURE. IF
PUMP IS SUBJECTED TO RAPID CYCLING DURING NORMAL OPERATION,
DAMAGE MAY OCCUR
