6.12 SPRAYER CLEANING ______________________________________________________
After use, clean the sprayer thoroughly with a cleaning
solution. During cleaning, always follow these guidelines.
1.
Use care when opening sprayer tank cover.
Potentially dangerous chemical fumes may have
accumulated inside tank.
2.
Type of cleaning solution required is determined by
chemical used in sprayer. Refer to the chemical
label for cleaning solution compatibility and specific
cleaning instructions.
3.
Sprayer cleaning should only be performed in an
area with run-off recovery or containment. If one is
not available, be certain the run-off does not
contaminate water supplies, public sewers, or
natural wet land areas. Check your local regulations
for requirements in your area.
4.
Remove the nozzles from spray booms. Clean
nozzle tips and screens in a strong detergent
solution or kerosene using a soft bristled toothbrush.
5.
Flush the sprayer system with clean water.
6.
Add a mixture of 2 pounds (0.91 kg) of cleaning
solution for each 30 to 40 gallons (114 to 152 l) of
water. This should be sufficient for removing most
pesticides.
7.
Close hose reel and/or boom supply valves. Operate
pump to allow cleaning solution to circulate through
the system and agitate in the tank thoroughly. Open
supply valves and allow detergent solution to flow
through remainder of the system for several
minutes.
8.
Flush the system twice with clean water.
9.
During the cleaning, examine the hoses, clamps,
connections, no-drip valves, nozzle tips, and
screens. Replace any components if damaged,
leaking or not functioning properly.
Special Cleaning Requirements:
1.
Some pesticide combinations (especially if oil is
used) may produce a putty like paste inside the tank.
a.
Flushing out residue of such chemicals after
each load will help prevent accumulation.
b.
If water alone does not remove the build up, add
a solution equal to 1 gallon (3.8 l) or solvent
(Stoddard solvent, kerosene, or diesel fuel) per
25 gallons (95 l) or water. Allow the paste to
dissolve then agitate and flush the system.
2.
If phenoxy herbicides, such as 2,4-D, have been
used in the system:
a.
Rinse the tank with clean water.
b.
Mix one of the following chemicals with 25
gallons (95 l) of clean water.
• 1 Quart (0.95 l) household ammonia.
• 1 Pound (0.45 kg) of washing soda (sal soda).
• 2 Pounds (0.91 kg) of trisodium phosphate.
c.
Rinse inside of tank with solution. Allow mixture
to agitate in tank and let a small amount flow
through the nozzles.
d.
Keep remainder of mixture in the system
overnight and pump it out in the morning.
e.
Rinse and flush the system with clean water.
WARNING
Sprayer cleaning solutions are chemicals and should be
given the same attention as chemicals used during
sprayer operation. Special safety equipment may be
required to prevent accidental exposure to poisoning
and should be worn at all times when working with
chemicals.
Contact your chemical supplier for proper material
handling. Always refer to the chemical manufacturers
MSDS (Material Safety Data Sheet), that is available for
all chemicals. Special attention should be given to
required safety equipment, first aid treatment for
accidental inhalation, swallowing, absorption or
injection, and compatibility with other chemicals.
Never work with harmful chemicals alone. Always have a
second person nearby in case of emergency.
Some chemicals and cleaning solutions may be
flammable or produce flammable vapors.
• Do not smoke when handling or mixing chemicals.
• Never store chemicals near an open flame or
spark which could ignite chemical or chemical
vapors.
