4. Rotate the lower Tank Drain Valve
(located beneath platform behind solu-
tion tank) to the OPEN (On) position to
drain chemical.
5.
When finished draining tank
, rotate the
lower Tank Drain Valve to the CLOSED
(Off) position.
6. Rotate the upper Tank Drain Valve to the
CLOSED (Off) position (perpendicular to
valve body).
7. Remove Drain Hose from collection con-
tainer and place back into stored posi-
tion.
8. Repeat steps to drain additional chemi-
cal tank -
if equipped
(using the corre-
sponding upper and lower tank drain
valves).
Further Information
Refer to the Raven manufacturer’s
operation manual for complete operating and
calibration instructions, troubleshooting tips,
safety precautions, and maintenance
information.
APPLICATION
It is important to apply chemicals as
recommended by the manufacturer. In order
to do so, the spray system console must be
properly calibrated.
NOTE: Refer to the spray system console
manufacturer’s operation manual for
calibration instructions.
Determine the speed in which the sprayer
will travel when applying chemicals. To
select the best speed, consider the lay of the
land, condition of the soil, type of crop, height
of crop, etc.
Remember that the performance of the
nozzles (spray tips) and spray system are
dependent on the performance of the
operator. If the spray system is operated
within set parameters of the nozzle type and
spray system console, you will see greater
success with your application. Operating the
machine one or two miles per hour (1.6 to 3.2
km/h) faster or slower than intended can
greatly change the pressure and droplet size.
Select nozzle spacing (distance between
each nozzle on the spray boom) that is best
suited for the intended spray application. For
recommendation in determining nozzle
spacing and height of the boom, visit
www.teejet.com
for further information.
There are various types and sizes of
nozzles. Select
and install the appropriate
nozzle best suited for the intended spray
application. The type of nozzle will depend
on the product being applied and the type of
crop that it is being used on. The size of
nozzles selected will be based on the speed
in which the machine will travel, nozzle
spacing, desired droplet size, and the
number of gallons per acre (GPA)/liters per
hectare (l/ha) that will be applied.
Nozzle Selection
There are several things to consider when
selecting the correct nozzle type for the
intended spray application. Whatever your
personal preference is, ensure that the
nozzle complies with the chemical
manufacturer’s standards for spray control
and also any environmental standards for
your region.
