Operation – Using the Sprayer
9. Sprayer
Pattern
A. Ensure correct spray pattern
Make sure both boom nozzles are pointed toward the ground. If they are not,
loosen the nozzle retaining nut, orient the opening of the boom nozzle to point
straight down, then retighten the nozzle retaining nut.
IMPORTANT:
Make sure broadcast nozzles are oriented to spray straight down
before you start. An incorrectly positioned broadcast nozzle may spray chemicals
on you or others.
Note:
It is not unusual for the operator to be exposed to chemical drips while
adjusting the broadcast nozzle. Chemical resistant gloves should be worn.
B. Ensure uniform coverage
To ensure proper coverage, the height of the unfolded boom nozzles should be
about 21'' from the ground. The sprayer must be level with the ground to get this
height.
The overall spray width is 120'', but 1/3 or 40'' of the overall spray pattern must be
overlapped to get equal coverage throughout the spray area.
Use the tables in Appendix A to determine what speed to drive your vehicle for the
desired application rate
C.
Begin to spray
Turn the remote switch ON to begin spraying.
10. Leaving
unattended
If the sprayer must be left unattended at any time
:
a)
Disconnect power to the sprayer.
b)
Relieve system pressure by depressing the gun trigger.
c)
Turn off the vehicle. Set brake or block the wheels.
11. Discontinue
use if clogged
or inoperative
If the sprayer becomes clogged or inoperative during use, discontinue use
immediately.
- DO NOT attempt to service while chemicals are in the sprayer and power is
connected.
- Return to service area to review instructions for troubleshooting before attempting
to service.
12. Pump
Overheating
This pump is equipped with a thermal protector.
This feature helps to protect the
pump from overheating and causing damage. If the pump shell reaches 180°F, the
pump will turn off. When the temperature of the pump shell drops below 145°F, the
pump will turn back on.
Note: A reserve, clean container capable of holding at least 21 gallons (call NorthStar Product Support at 1-800-
270-0810 and order Item #793294) should be kept for use when the sprayer tank needs to be emptied
temporarily for repairs. It is advisable to purchase a reserve tank suitable for pesticide storage from
Northern Tool + Equipment for use in these circumstances. The container should be properly labeled as to its
contents if it is used.
