Storage
1. Empty solution from the tank, clean the chemical
inductor (if included), and store or dispose of the
chemical as recommended by the manufacturer’s
chemical label.
2. Flush the entire sprayer system with clean water.
3. Clean out Whirlfilters®. See “Whirlfilter® Clean-
Out” on page 44.
4. Circulate 3 - 5 gallons (11-19 liters) of antifreeze
(Great Plains strongly recommends the use of recre-
ational vehicle antifreeze) through the system includ-
ing the pump, hoses and nozzles.
5. A cast iron pump must be either full of RV antifreeze
or completely empty of all liquid to avoid corrosion. If
the contents of the pump is unclear it is advisable to
drain the pump, remove it, and place it in a warm dry,
environment during the winter.
IMPORTANT !
Regular antifreeze is harmful or fatal to animals and
humans. Use carefully according to the label’s instruc-
tions. We strongly recommend the use of recreational
vehicle (RV) antifreeze which does not exhibit these
harmful side effects.
6. Remove nozzles, disconnect the control box, and
place them indoors with the pump.
7. Wash off the exterior of the sprayer thoroughly using
a safe solvent or soap and water.
8. Inspect all parts of the sprayer for wear and rust.
Repair and paint parts as necessary.
9. Fully retract all cylinders to prevent rust on exposed
rods. Where cylinders do not fully retract, either dis-
connect rod ends to allow retraction, or coat exposed
rods with grease.
IMPORTANT !
Remove grease prior to next use to prevent seal dam-
age.
10. Store the sprayer in a dry area away from direct sun-
light, where children do not play.
