Section 4
6. Watch for plugged sprayer nozzles.
7. Move the sprayer boom control valves to the OFF
position to stop the flow of product before stopping
the forward motion of the machine.
8. Use adequate pump pressure for proper spray
distribution.
9. Watch for any changes in application rate.
WARNING
DO NOT operate without the proper training or
applicable licenses(vary by state). Operation
without aforementioned items can result in harm/
lawful action to yourself or others.
10. Replace damaged or worn nozzles (Refer to section
6-7 for determining nozzle wear/damage).
4.19 RECOMMENDATIONS FOR SPRAYING
WITH THE SPRAY WAND
WARNING
The spray wand traps liquid under high pressure,
even when the engine is off. High pressure
discharge could cause serious injury or death.
1. Keep clear of the nozzle and do not direct the spray
wand at people, pets or non-work area.
2. Do not direct the spray towards or near electrical
power sources or components.
3. Do not attach hoses or other components at the end
of the spray wand.
4. Do not attempt to disconnect the spray wand from
the machine while the sprayer system is pressurized.
5. Lock the spray wand to the OFF position when the
job is complete.
6. Do not repair the spray wand, hoses, seals, nozzle,
or other wand components, Always replace them.
4.20 RECOMMENDATIONS FOR
SPREADING
1. Before spreading make sure the area is clear of
objects that may be contaminated with chemicals
and ingested or used after (Ex. dog-bones or
children's toys).
2. Make sure to calibrate the spreader to the desired
application rate. Refer to Calibrating The Spreader
Section 6-8 for information on calibrating the
spreader.
3. Spread material back, roughly, to the last pass' tire
marks from your previous pass.
4. Make sure to properly dispose or store all unused
chemicals according to the manufacturer's directions.
WARNING
DO NOT operate without the proper training or
applicable licenses(vary by state). Operation
without aforementioned items can result in harm/
lawful action to yourself or others.
4.21 RECOMMENDATIONS FOR
SPREADING AND SPRAYING AT THE SAME
TIME
1. Before spreading/spraying make sure the area is
clear of objects that may be contaminated with
chemicals and ingested or used after (Ex. dog-
bones or children's toys).
2. When spreading and spraying at the same time,
the spreader will need to be calibrated to spread
material at twice the spraying width. This will assure
proper overlap and application rates for both
systems. (Ex. If you're spraying with a 6ft spray
width, your effective spread width will need to be
12ft.) Refer to Section 6-7 and 6-8 for calibration
procedures.
3. The spreader should spread back to the center
of the tire marks from your previous pass and the
spray boom tip should be about 20" away from the
previous boom pass.
4. During calibration, the speed (mph) should be
determined while doing the sprayer calibration. Make
sure to use the same speed while calibrating the
spreader.
5. Make sure both the sprayer and the spreader are
properly calibrated for the material to be spread and
sprayed.
