SPRAYER CALIBRATION, ADJUSTMENT, AND OPERATION
Description of Sprayer features, controls, and operation
The spray pattern and spray rate are controlled by the engine speed and pump pressure, and
the nozzle orifice. These are constants that do not change unless the machine or a component
is not functioning correctly or is misaligned. An unloader valve inside the tank controls pump
pressure. There is a suction shutoff valve located at the tank outlet. A strainer is located inside
the tank. A spray control lever is mounted on the left handle to turn the spray on and off.
There is a pair of nozzles (broadcast & trim) for use while in LOW gear, and a second pair of
nozzles (broadcast and trim) for use in HIGH gear. The standard nozzles are sized to apply
approximately 1 quart per thousand square feet in either gear whether broadcasting or trimming.
An optional kit is available that has nozzles sized to apply approximately ½ gallon per thousand
square feet. Tank mounted spray selector valves control which nozzle sprays.
The sprayer has a pattern width of 11 feet (3.4 meters) using a single front mounted broadcast
nozzle, as shown in Figure 9. The spray distribution pattern allows the use of the seven-foot
(2.1 meters) overlap spreader travel pattern to achieve an even distribution of the sprayed
product. Using the trim nozzle provides an even finished distribution using a single trim nozzle
to deliver a spray pattern of 3 feet on the surface being treated.
The sprayer and spreader can be operated at the same time and provide even distribution of
both the sprayed and spread products.
The Sprayer requires periodic calibration and adjustment to verify the sprayer patterns
and to verify the correct product delivery rates
.
Whenever you change products or rates
of application and at one-month intervals, or more frequently during heavy use, verify
that calibration is still valid. Adjust as necessary.
Check and adjust Broadcast Spray pattern daily, prior to treating each lawn, and as
needed to verify that the nozzles are properly aligned and spraying properly.
After completing spreader calibration, you should regularly compare the amount of
product used to the number of square feet covered.
Before handling, mixing, or applying any pesticides, read and follow
product label and material safety data sheet. Some materials may
present health hazards and will require protective clothing and/or
breathing equipment. Follow product label and MSDS disposal
instructions and any local regulations that apply to the product
