Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With systematic inspection and
lubrication, you can avoid many costly repairs and down-
time. Always turn off and remove tractor key before mak-
ing any adjustments or performing maintenance.
!
WARNING!
You may be severely injured or killed by being crushed under
falling openers or wings. Always have openers hydraulically
locked up and wing lock pins in place when working on imple-
ment.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. 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. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result.
!
CAUTION!
Opener disks are sharp enough to cut flesh. Use caution when
working around the opener disks.
1. After initially running implement for several hours,
check all bolts to be sure they are tightened as speci-
fied on Torque Values Chart, “Appendix,” page 30. Do
not over tighten bolts holding distribution towers
together.
2. Lubricate implement. See Lubrication, this page.
3. Maintain correct pressure in tires. See Tire Inflation
Chart, “Appendix,” page 30.
4. Replace any worn, damaged or illegible safety labels
at once. Refer to Safety Labels, “Important Safely
Information,” page 1, for correct label placement.
Obtain new labels from your Great Plains dealer.
5. Clean or replace any fittings that will not take grease.
6. Periodically check and secure all bolts, pins and fas-
teners. Tighten as specified on Torque Values Chart,
“Appendix,” page 30.
7. Occasionally inspect hydraulic hoses for cuts, cracks
and aging. Check fittings and cylinders for leaks.
8. Inspect cart link pins for wear or loosening.
Storage
Store implement in an area where children do not play. If
possible, store implement inside for longer implement life.
1. If you store implement unfolded, unpin rod ends of the
fold cylinders and retract cylinders fully to prevent rust.
2. If cart is disconnected from implement for storage,
plug all 2 1/2-inch openings to prevent birds from nest-
ing in openings.
3. Check all seed hoses for pinching or kinks. Relieve
any sharp bends before storing implement.
4. Lubricate implement at all points indicated under
Lubrication, this page.
5. Check all bolts, pins, fitting and hoses. Tighten, repair
or replace parts as needed.
6. Check all moving and soil-contact parts for wear or
damage. Make note of any parts needing repair
before next drilling season.
7. To prevent rust, use Great Plains touch-up paint to
cover scratches, chips and worn areas.
