ASSEMBLY
The Master Gardner is assembled at the factory with the exception of a few components to protect them from
shipping damage. Follow the steps below to complete assembly:
Hooking up pump to battery source
1.) Remove the sprayer from the carton and gently tip the sprayer upside down onto the tank lid.
2.) Looking underneath the back panel, locate the (2) black two pin connectors. One from the pump and
the other from the wiring harness leading to the battery (neither of these wires should have any labels
on them) Plug these two connectors together securely.
Caution: Do not hook up the red connector labeled “Remote Switch” to anything but the remote
switch. This will cause the fuse to blow.
Handle Assembly
1.) Remove sprayer and components from Carton.
2.) Locate and remove the two bags of components from within the tank. Open the parts bag labeled;
“Acc. Bag” and remove these instructions. Read instructions in their entirety before proceeding.
3.) Slide handle (Item 1, figure A) into lower frame (Item 7, figure A). Adjust handle height to a
comfortable setting for the operator. Adjust handle to align the holes in handle and lower frame closest
to desired setting.
4.) Using the two handle adjustment knobs and bolts (Item 2, figure A), insert bolts through holes in handle
and tighten with knobs.
Front Deflector Nozzle Attachment
Note: If nozzle is assembly is complete proceed to step 4.
1.) Locate the bag labeled Nozzle Assembly.
2.) Insert Nozzle body fitting (Item 7, figure B), through the nozzle bracket (Item 8, figure B), and hold in
place with nozzle body nut (Item 9, figure B) tightened loosely by hand.
3.) Insert nozzle filter (Item 9, figure B) into nozzle body. Place deflector nozzle (Item 11, figure B) into
nozzle nut (Item 12, figure B). Thread nozzle nut with nozzle onto nozzle body fitting and tighten
slightly.
4.) Attach Nozzle bracket to tank (Item 16, figure B) with two screws and washers. Tighten securely.
5.) Locate clear vinyl hose from bottom front of tank. Attach hose to nozzle body fitting attached to front
of tank with hose clamp (Item 17, figure B).
6.) Tighten all nuts and screws securely ensuring the nozzle is pointing directly down towards the ground.
Using the Master Gardner as a Trailer
If the Master Gardner will be used with a garden tractor a trailer tongue can be attached to the sprayer for
towing. A “Remote Switch” is also supplied so the sprayer pump can be remotely operated from the
tractor. If the Master Gardner will be used as a trailer, follow the instructions below:
1.) Locate the remote switch wiring harness from the accessory bag.
2.) Locate the sprayer wiring harness connector near the opening on the bottom of the black pump shield
on the back of the sprayer. The two pin red connector will be labeled “Remote Switch”. Attach the
red two pin connector from the Remote Switch to the red connector on the sprayer.
3.) Attach the trailer tongue (Item 8, figure B) to the sprayer frame (Item 7, figure B) aligning the holes and
using the pin and hair pin (Item 3, figure B).
Setup
Charging the Battery
1.) Obtain the battery charger (Item 27, figure B) and plug the charger into an AC wall outlet and the other
end into the charging port located on the sprayer.
2.) Allow the charger to charge the battery until the light on the charger turns from red to green. A green
light indicated the battery is fully charged. A red light indicates the batter needs charging. A
discharged battery could take as long as 24 hours to recharge.
3.) Never allow the battery to discharge completely. Doing so may damage or shorten battery life and void
warranty.
Testing
1.) Always test the sprayer with clean water prior to spraying with a chemical mixture. This will
allow the sprayer to be inspected for leaks and repaired before expensive chemicals are used.
Using the front Deflector Nozzle
1.) Four things must be considered before spraying with the boom.
1.) How much chemical must be mixed in the tank?
Refer to the chemical label to determine the chemical mixture
2.) Rate of spray (gallons per acre to be sprayed.
See the Tip Chart below to determine the gallons per acre. The chart will also show the
speed used when spraying.
3.) Speed traveled (M.P.H.) while spraying.
Refer to the Tip Chart and Speed Chart below for MPH.
Determine Gallons per Minute
Once you know how much you are going to spray then determine (from the tip chart) the spraying pressure
(PSI) and the spraying speed (MPH). The pressure is preset by the pump, typically between 30 to 35 psi,
but it will vary depending on the percentage of charge left in the battery. If precise chemical metering is
desired, then the battery should be fully charged and a flow rate should be measured at the nozzle. After
the battery is fully charged, obtain a bucket and place under the nozzle. Turn the valve on to begin
spraying water into the bucket while timing. Allow the sprayer to run for 1 minute and then turn off
sprayer. Measure the amount of water within the bucket to obtain the exact GPM of the pump and nozzle.

Caution
Do not spray on windy days. Protective clothing must be worn in some cases. Be sure to read the
chemical label carefully. After all calibrations have been completed, add water and chemical to the
tank. Always follow chemical manufacturer’s instructions for mixing.
Operation
Ensure battery is fully charged to provide optimum efficiency from the 12volt pump. Turn the valve
located in the back panel to the off position. This will ensure the nozzle does not begin to spray when the
pump is activated. The pump can be operated with the switch located on the back panel or from the remote
harness if connected. Remove the tank lid and then fill the spray tank with clean water through the basket
strainer. (Inspect tank for leaks at this time) Slowly pour in the desired amount of chemical.
Activate the pump by turning on either switch. (The pump will run with either switch in the on position. If
both switches are in the on position then both will need to be turned off to disconnect power.) The pump,
when activated, will begin to run until 40 psi is reached. The built in pressure switch will then shut off the
pump. Your sprayer is now ready.
To spray with the wand, ensure the wand nozzle is pointed in the direction meant to be sprayed and pull the
lever handle. The pump will automatically activate and the wand will disperse the chemical mixture from
the tank. To stop spraying with the wand release the lever handle on the spray wand and the pump will
deactivate after reaching pressure.
To spray with the nozzle located on the front of the tank, ensure the wand is firmly attached to the tank or
frame handle. Turn the valve located on the back panel to the ON position. The nozzle on the front of the
tank will begin to spray. Immediately begin to push or pull the sprayer at the desired speed for proper
chemical delivery. To stop spraying with front nozzle, turn off the valve and the pump will deactivate after
reaching pressure.
When spraying is complete, turn off the main power switch and or remote switch for storage. This will
stop the pump from running periodically and increase battery life.
CLEANING & STORAGE
Most spray materials are highly corrosive. The most important aspect of long dependable service from the
sprayer is a thorough cleaning immediately following each use. In addition, the residue of one type of
chemical could cause an undesirable effect when a different chemical is used for a different purpose.
The most effective cleaning method is to pump several rinses of clean water through the tank, pump, hoses,
boom, spray gun, etc. A neutralizing agent such as a solution of Nutra-Sol, a detergent or household
ammonia as recommended by the chemical manufacturer can assist in removal of a persistent chemical.
When the system is thoroughly cleaned drain the tank, suction line, pump, hoses, etc.
The following steps should be followed for the maintenance and storage of your sprayer.
1. Wash and flush out sprayer after completion of each phase of your program. Flush out sprayer when
changing chemicals if there is a possibility of the chemicals being incompatible. Use of a detergent is
advisable if the chemical manufacturer does not make specific cleaning recommendations. Flush
system completely, including nozzles. Never use metal objects to open clogged nozzles.
2. Clean sprayer thoroughly before storing at the end of the spraying season. Permanent
type anti-freeze added to the final rinse will leave a rust inhibiting film in parts of the sprayer.
3. Periodically charge the battery (every 3 months) even if sprayer is not being used.
TROUBLE SHOOTING
Pump will not turn on:
1. Ensure the power switch or remote switch is in the on position (the I position is on and the O position is
off).
2. Ensure the battery is fully charged. Refer to SETUP: charging the battery.
3. Ensure all battery connections are tight.
Confirm the pump is hooked up to the battery source.
Confirm battery connections are made and tight.
Inspect connections on the back of the switch and be sure they are attached.
4. Inspect the fuse located under the back panel.
Drain any chemical or water that may still exist in the sprayer. Rinse the tank with clean water.
Turn the sprayer upside down and locate an inline fuse holder on the wiring harness under the
battery cover on the back of the sprayer. Take the 10 amp fuse out of its holder and while
holding the fuse up to the light ensure there are no breaks in the fuse wire. If you can see any
gaps, the fuse will need to be replaced. (If fuse is discharged make sure all of the connections
from the battery and remote switch are hooked up correctly before replacing the fuse)
5. Check to make sure the pump has power.
If possible take a volt meter and make sure power is getting to the pump. If the pump is not
getting power, inspect all connections to find out where power is lost.
Check the pressure switch. You can check if your pressure switch is working by taking the 2
leads going into your pressure switch and jumping them together. You can do this with a spare
wire or piece of metal. If the pump turns on you have a bad pressure switch and will need a new
pump.
If at this point the pump doesn’t turn on try hooking the pump up to a secondary 12v battery
source (such as a car or ATV battery) to see if the pump turns on. If the pump turns on, there is
either a bad battery or a bad connection preventing the full 12 volts to get to your pump.
Pump will not prime:
1. Inspect to make sure water is above inlet hole
2. Inspect hoses to be sure of no kinks or blockage.
3. Put warm water through the inlet line to see if it can break up any blockage in the check-valves. (repeat
this process for a couple minutes to make sure it gets all of the substance out)
Pump cycles on and off:
1. Adjust the spray tip of your wand to relieve some pressure on the pump. Reducing the cycling you’re
your pump makes will extend the life of the pump and pressure switch.
