Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With careful and systematic in-
spection, you can avoid costly maintenance, time and re-
pair.
Equipment Cleanup
Nozzles should be cleaned with a low pressure (less than
30 psi) air hose, and periodically replaced. Haul a supply
tank of water so you can clean the spray tank and applica-
tor out in the field. Never wash tank out in the yard or at a
car wash.
Dispose of left-over chemical in the same manner de-
scribed on the manufacture’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.
General Information
If equipment is to be used in freezing or near freezing con-
ditions, protect pump and plumbing system by thoroughly
draining liquid and pumping antifreeze solution through
system to coat the interior of the pump and plumbing.
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 system is relieved.
Check the conditions of hoses and connections frequently.
Release the system pressure before working on the spray-
er. To release the pressure flip the boom section switches
on and off without the pump running. Always wear rubber
gloves when making repairs or adjustments. Make sure all
Protective Equipment (gloves, goggles, etc.) listed on
page 5, are stored in an easily accessible place but pro-
tected from potential contamination from dust or chemi-
cals.
Check the sprayer for any loose bolts, pins, and hose
clamps.
Check the hoses, pumps, valves, and fittings for any leaks.
Inspect all parts of the sprayer for wear and rust. Repair
and paint parts as necessary.
Storage
1. Empty solution from your sprayer tank and store or
dispose of the chemical as recommended by the man-
ufacturer’s chemical label.
2. Change filters in the tractor cab after finished.
3. Wash off the exterior of the boom thoroughly using a
safe solvent or soap and water.
4. Flush the boom out with antifreeze (Great Plains
strongly recommends the use of RV antifreeze) to pre-
vent damage to components when a freeze occurs.
5. Inspect all parts of the sprayer boom for wear and rust.
Repair and paint parts as necessary.
6. Store the boom in a dry area away from direct sun-
light. Follow the instructions to park the boom. Refer to
Parking on page 15.

The grease zerks are located in the shaft on the lower pivots
and in the tube on the upper pivots. Grease until you just be-
gin to see grease come out.
