Product Manual

WETTABLE POWDERS:
Avoid use in piston pump sprayers models 425, 425-L,
435, 425-PAF, 473-P! The Solo models 475, 475-3N1,
475-PAF, 473-D, 478 and 485 sprayers with a diaphragm
pump are generally resistant to abrasive materials and
are recommended for this purpose. Note: If you use a
wettable powder in your 425, 435, 473-P sprayer, be
sure that it is thoroughly mixed in the formula solution.
Immediately after use, be sure to remove the piston,
clean and lubricate the Viton
®
collar with Solo Superior
Grease* or petroleum jelly. Thorough flushing of sprayer
will extend the life of its working parts. If you use wettable
powders in the piston pump sprayer, be sure to inspect
regularly for seepage around the piston and repair
accordingly.
CLEANING:
• After spraying, clean the tank thoroughly. If some spray
liquid is left inside, drain tank completely.
• Pumping causes air to be taken in and the remaining
liquid to be discharged. Pump until liquid and air are
coming out through the nozzle.
• Refill tank with a few quarts of clean, soapy water and
pump the water out as explained above (if necessary,
repeat this procedure several times).
• If the shut-off valve is removed, the pump can be
flushed quickly. Improper spray distribution is the result of
a clogged nozzle, which is easily removed and cleaned.
• Soap and water may also be used to clean tank.
• Do not use aggressive cleaning agents or abrasives.
• Follow the recommendations of the chemical
manufacturer for disposal of waste water and
chemicals.
• Activated charcoal in liquid or other form may be used to
absorb chemicals in tanks or spills.
NOTE: When cleaning the sprayer after working with
hormone weedkillers, follow the instructions of the
herbicide producers. Neutralize with activated charcoal.
(Example: add 0.35 oz./1 g. of activated charcoal to 1.7
pint/1 liter of water and leave this detergent in the tank and
the lines approximately for 24 hours.) This is very important
if other chemicals should be sprayed as the residues of the
herbicide may damage susceptible plants. Cleaning after
application of products containing carbolineum, if they
are not water soluble, should be done with a 5% soda lye
having a temperature of 104°F (40°C). Rinse with plenty of
clean water.
MAINTENANCE AND STORAGE TIPS:
To protect the piston, cylinder and Viton
®
collar, these
parts should be lubricated with Solo Superior Grease* or
petroleum jelly at least once per
season.
If you find that your sprayer
will not empty the formula tank,
check for a clogged inlet open-
ing (2). The inlet screen is locat-
ed at the bottom of the pressure
cylinder on the side that faces
your back.
One indication that it needs
cleaning is that when you let
go of the pump handle, it
“springs” to the down position.
The opening can be cleaned
with a small bristle brush or
a discarded toothbrush. See
diagram for location of opening.
• After operation, the sprayer should be stored away from
direct sunlight to prevent UV damage.
• After removing the pump or when mounting a new Viton
®
collar, treat both the collar and the piston with water-
resistant grease.*
• Before winter, drain all liquid in tank, lines and air
chamber. (See “Cleaning.”) Leave shut-off valve locked
in the “open” position.
• For service, visit our website to locate your nearest Solo
dealer. Always insist on original Solo spare parts.
• Regularly inspect hose, wand, pump, tank and shut-off
valve for wear, damage or leaks. Repair promptly.
• Occasionally lubricate cap gasket.*
Avoid excessive wear by:
1) Regular lubrication of Viton
®
collar, cylinder and piston
with water resistant grease.*
2) Prompt and thorough cleaning and flushing of sprayer.
Soap and water work well.
*Use Solo Superior Grease (#9850-P). Petroleum jelly may also be used.
