Maintenance and Lubrication
General Maintenance
Proper servicing and adjustment is the key to long imple-
ment 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 maintenance. Securely
block tires before working under or around drill.
!
DANGER!
Some chemicals will cause serious burns, lung damage and
death. Avoid contact with skin or eyes. Wear proper protective
equipment as required by chemical manufacturer. Avoid pro-
longed breathing of chemical fumes. Wear respirator as re-
quired by chemical manufacturer. Seek medical assistance
immediately if accident occurs. Know what to do in case of an
accident.
!
WARNING!
You may be severely injured or killed by being crushed from a
falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
!
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 an accident
occurs, immediate medical attention from a physician familiar
with this type of injury.
1. After using your drill for several hours, check all bolts
to be sure they are tight. Periodically check and se-
cure all bolts, pins and fasteners. Tighten as specified
on Torque Values Chart, “Appendix,” page 44.
2. Clean or replace any fittings that will not take grease.
Lubricate the drill as noted under Lubrication, “Main-
tenance and Lubrication,” this page.
3. Clean nozzles on optional rear-mount boom with a low
pressure (less than 30 psi) air hose. Periodically re-
place nozzles. Always wear rubber gloves when mak-
ing repairs or adjustments.
4. Adjust idlers to remove excess slack from chains. Ad-
just gauge-wheel arm drive chain as explained under
Gauge-Wheel Drive Adjustment, “Adjustments,”
page 28. Clean and use chain lube on all roller chains
as needed.
5. Always maintain correct tire pressure. Refer to Tire In-
flation Chart, “Appendix,” page 44.
6. Inspect hydraulic hoses for cuts, cracks and aging.
Check fittings and cylinders for evidence of leaks.
7. Replace any worn, damaged or illegible safety labels
at once. Refer to Safety Labels, “Important Safety In-
formation,” page 5, for correct label placement. Ob-
tain new labels from your Great Plains dealer.
Storage
Store the drill where children do not play. If possible, store
the drill inside for longer life.
1. If you store the drill in the unfolded position, unpin and
fully retract the fold cylinders to prevent rust.
2. Clean the drill as necessary. Be sure that the seed
boxes are cleaned completely before storing.
3. Disconnect seed hoses from openers. Premature
hose damage will occur if drill is stored with hoses
connected.
4. Adjust idlers to remove excess slack from chains. Ad-
just gauge-wheel arm drive chain as explained under
Gauge-Wheel Drive Adjustment, “Adjustments,”
page 28. Clean and use chain lube on all roller chains
as needed.
5. Lubricate the drill at all points indicated under Lubrica-
tion, this page. Be sure the seed-cup drive sprocket is
oiled before the drill is stored.
6. Check all bolts, pins, fitting and hoses. Tighten, repair
or replace parts as needed.
7. Check all moving and soil-contact parts for wear or
damage. Make notes of any parts needing repair.
8. Use Great Plains touch-up paint to cover scratches,
chips and worn areas to prevent rust.
