Master Manufacturing 10 Boom Kit - Manual (Page 3)

∞ See the tip chart to determine the pressure to be used. The chart will also show the speed used when
spraying.
∞ Open the valve lever to the boom nozzles.
∞ Check the spray pattern. Usually you can see the coverage better on solid concrete surface, such as a
driveway.
∞ Raise or lower the nozzles so that you will have a good coverage pattern. If you can see dry spots on the
concrete surface you will need to raise the nozzles. Too much solution in the pattern areas means you
need to lower the nozzles. Generally the proper height will be from 13 inches to 18 inches from the area
to be sprayed.
Operation and Maintenance
The nozzles on the boom will spray a 120” wide swath. The nozzle height is approximately 15” above the
object being sprayed.
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 can be set by running the sprayer with the boom nozzles
“ON” and then by adjusting the garden hose valve lever until the gauge reads the desired pressure. Notice that
the pressure will go up when the garden hose valve is slowly closed.
When selecting pressure from the tip chart, it is a good idea to try for the 20 or 30 PSI range as this allows an
excellent nozzle pattern. At 10 PSI the pattern begins to break up and at 40 PSI you may notice some drift.
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 carefully.
After all calibrations have been completed, add water and chemical to the tank. Always follow chemical
manufacturer’s instructions for mixing.
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.
