Maintenance and Lubrication
Maintenance
Proper servicing and maintenance is the key to long
applicator life. With careful and systematic inspection,
you can avoid costly maintenance, downtime, and repair.
Always turn off and remove the tractor key before making
any adjustments or performing any maintenance.
Suffocation, Blinding, Burning, Freezing, Disabling and
Disfigurement Hazards:
Do not perform maintenance with anhydrous ammonia in the
system. Fully discharge the system of NH
3
liquid and vapor
before working on the applicator. See page 110.
Crushing Hazard:
Always have transport locks and/or parking stands in place
when working on applicator. You may be severely injured or
killed by being crushed under a falling applicator.
High Pressure Fluid Hazard:
Check all hydraulic lines and fittings before applying pressure.
Fluid escaping from a very small hole can be almost invisible.
Use paper or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin. If
an accident occurs, seek immediate medical assistance from a
physician familiar with this type of injury.
1. After using your fertilizer applicator for several hours,
check all bolts to be sure they are tight.
2. Remove excess slack from chains. Clean and use
chain lube on all roller chains as needed.
3. Maintain proper air pressure in fertilizer applicator
tires.
4. Clean fertilizer applicator on a regular basis. Regular
and thorough cleaning will lengthen equipment life
and reduce maintenance and repair.
5. Lubricate areas listed under “Lubrication and
Scheduled Maintenance” on page 126.
6. Replace any worn, damaged, or illegible safety
labels by obtaining new labels from your Great
Plains dealer.
