GENERAL OPERATION &
MAINTENANCE
The sprayer pump is turned on and off by the thumb
switch mounted on the handlebar of the spreader. Each
dripless nozzle body has a special shut-off cap. The
nozzle body requires 5 psi of system pressure to open,
thus keeping the nozzles from dripping when the pump
is off. The nozzles can be completely shut off by turning
the cap clockwise. The operator can turn off individual
nozzles as needed. The hand spray wand is activated
by closing the boom line valve (ball valve on top of the
tank) to turn off flow to the boom. To drain the tank of
unused liquids, remove the spray tip from the wand and
pump the remaining liquid into the proper receptacle.
• Clean pump filter daily.
• Clean tip screens regularly.
• Prevent from freezing.
• Adjust hinge lock nut tension as necessary.
• Flush with water after each use.
• Lubricate hinges with grease.
INITIAL START-UP
& PRESSURE TESTING
1. Turn the pressure regulator knob counter-
clockwise all the way.
2. Put about one gallon of water in the tank for
testing.
3. Be sure that the spray line valve is turned off.
4. Turn on the handlebar thumb switch. You should
hear the pump running and see water moving
through the hoses.
5. Slowly turn the pressure regulator knob clockwise
to increase the pressure. You should notice
movement of the needle on the pressure gauge.
Adjust the pressure to 30 psi for testing.
6. With the spray wand assembled, operate the
trigger valve and check it for leaks. Note the
trigger lock. Also adjust the nozzle and angle
adapter orientation to the desired position.
7. Turn off the switch. Turn on the boom line valve
and all four caps on the top of each boom nozzle
body.
8. Turn on the switch and observe the spray pattern
from each boom nozzle. Check the entire boom
assembly for leaks.
9. Flush out the water and antifreeze. Once the unit
has been pressure tested and you are familiar
with its operation, you can begin the calibration
procedure.
