Master Manufacturing MASTER GARDNER - Manual (Page 4)

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.
