SPRAYING:
Prime the pump with quick pump strokes. When you feel very firm resistance, the pressure chamber is filling with
liquid. With repeated piston strokes, the air in the pressure chamber is slowly compressed. In a safe area, point
the wand upward and press the shut-off valve lever spraying for 10 seconds or until no air and only liquid is com-
ing out. This will bleed all of the air out of the hose and wand. By pressing the hand lever, the valve opens, and liquid is
forced through the nozzle. The shut-off valve has a retaining clip which keeps the valve in the “OPEN” position for
continuous operation. Pump using the end of the pump handle, as it is less fatiguing. The volume of liquid delivered varies
with the working pressure which should be as high as needed to ensure an adequate spray pattern for each individual
application.
NOTE: Should the pressure drop very quickly, drain the tank completely and pump without liquid. By this procedure, the air
chamber is refilled with the required volume of air. It is advisable to pump the tank completely empty from time to time.
WETTABLE POWDERS:
Avoid use in piston pump sprayers models 425, 425-101 425-Prof, 425-HD, 315-A, 435, 473-P! The Solo models 475-B,
475-101, 475-Prof, 473-D, 473-ECS, 485 and 475-B-HD 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, 425-101, 425-Prof, 425-HD,
315-A, 435 or 473-P sprayer, be sure that it is thoroughly mixed in the formula solution. Immediately after use, be sure to
remove the piston and clean and lubricate the Viton
®
collar with Solo Superior Grease* or petroleum jelly. Thorough
flushing of the 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, lubricate and/or 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 weed killers, 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 will be
sprayed as the residues of the herbicide may damage susceptible plants. Cleaning after application of products containing
carbolineum, a coal tar wood preservative, is imperative. If the chemicals are not water soluble, cleaning should be done
with a 5% soda lye having a temperature of 104°F (40°C). Rinse with plenty of clean water.
