WARNING
Before working on, servicing or making adjustments on
sprayer, always disengage power, shut off tractor engine, make
sure all moving parts have stopped, and all pressure in the sys-
tem is relieved.
▲ Always wear rubber gloves when making repairs or adjust-
ments.
▲ Make sure all safety equipment mentioned in “Wear Pro-
tective Equipment” on page 2, are stored in an easily
accessible place but protected from potential contamination
from dust or chemicals.
General Information
If equipment is to be used in freezing or near freezing
conditions, protect pump and plumbing system by thor-
oughly draining liquid and pumping antifreeze (Great
Plains strongly recommends the use of recreational vehi-
cle antifreeze) solution through the plumbing system.
The 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, environ-
ment during the winter.
Check the condition of the sprayer hoses and clamps. Fix
all leaks by tightening hose clamps or fittings. If the pump
is leaking, refer to the pump maintenance section. If the
hoses are dragging when the sprayer is operated use
cable ties to fix their position. Make sure the hoses do
not bind or kink when the boom is folded or raised. If so,
route the hoses to prevent kinking and binding. If hoses
are damaged, replace as necessary. Periodically check
for loose bolts and tighten.
Inspect all parts of the sprayer for wear and rust. Repair
and paint parts as necessary.
Equipment Cleanup
Clean nozzles with a low pressure (less than 30 psi) air
hose. Replace worn nozzle parts. Haul a supply tank of
water for field cleaning of the spray tank and booms.
NEVER wash tank out in the yard or at a car wash.
Dispose of leftover chemical in the same manner
described on the manufacturer’s label of the chemical
last used in the sprayer. Rinse out the tank and spray the
rinse water on the last field that was sprayed.
Flush the sprayer with fresh water and spray the water in
the field that was last sprayed. While the sprayer is being
flushed at the field, turn the boom section switches “on”
to flush the nozzles, then turn them “off” to flush out the
bypass lines. Repeat this procedure several times.
Whirlfilter® Clean-Out
There are two Whirlfilters® on the Great Plains Sprayer.
One filters the water entering the tank and the other fil-
ters the chemical solution being sprayed.
