Introduction
SAFETY PRECAUTIONS
(CONTINUED)
This Console (PGM F) requires selection of US (acres); SI (hectares) or TU (1,000 sq ft) area and
SP1 (wheel drive, etc).
In the event of console power loss, the power down delay time will default to 10 days.
MEASURE CAREFULLY. Be sure tire is properly inflated before measuring. Measure tire in type
of soil in which you will be spraying. Circumference of tire will vary when measured in soft
soil versus hard packed soil. For best results, measure several times and average the results.
Re-measure periodically.
Running the Control Valve too fast will cause the system to oscillate. Range: 1 to 9, 1-slow, 9-
Fast
There are other acceptable and proven methods of calibrating a turf sprayer for application.
Other techniques may be more suitable depending on operational needs and technical
competence of the operator.
When selecting a new nozzle size refer to the “Discharge Rate Column” on the nozzle
charts. The Discharge Rate (gpm or lpm) multiplied by the number of nozzles should not
exceed 75% of the actual discharge volume of the sprayer pump. [i.e., if you need to use
nozzles which discharge 0.8 gpm (3.0 lpm), and the spray boom is equipped with 12 nozzles,
the sprayer pump would have to produce an actual discharge volume of 13 gpm (49 lpm) in
order to properly supply these nozzles.] If the collective volume of the spray boom nozzles
exceeds the actual discharge volume of the pump, inadequate pressure and poor nozzle
distribution patterns may result.
As a practical matter, if high application rates are desired (above 75 gpa), the measured
course length should be reduced by half (i.e. 102 ft (31m) for 20 inch (52cm) spaced nozzles).
The volume collected (above) is then doubled (multiplied by 2).
