Maintenance and Lubrication
Maintenance
Proper service and maintenance are the keys to long im-
plement life. With careful and systematic inspection, you
can avoid costly maintenance, downtime and repair.
You could be severely injured or killed by being crushed from a
falling implement. Always have opener transport locks and cyl-
inder lock channels in place when working on implement.
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.
This drill has a negative tongue weight when unfolded and
openers are raised. Lower parking stand, lower openers and re-
move hydraulic down pressure before unhitching the drill in the
unfolded position. Unhitching in the unfolded position with the
openers raised could result in sudden elevation of the tongue,
causing injury or death.
1. After using your drill for several hours, check all bolts
to be sure they are tight. Lubricate areas noted under
Lubrication, page 48.
2. Remove excess slack from chains. Clean and use
chain lube on all roller chains as needed.
3. Always maintain proper air pressure in drill tires.
4. Keep disk scrapers properly adjusted.
5. Clean drill on a regular basis. Regular and thorough
cleaning will lengthen equipment life and reduce
maintenance and repair.
6. Replace any worn, damaged or illegible safety labels by
obtaining new labels from your Great Plains dealer.
Marker Breakaway Protection
The marker arm is attached to the marker body with a 3/8-
inch, grade 2 shear bolt. It is identified as a grade 2 by hav-
ing no marks on the head.
If excessive force is applied to the marker during opera-
tion, the shear bolt will break and allow the marker arm to
swing away. If the bolt breaks, replace it with a grade 2 bolt
to prevent marker damage.
Openers
If the raising or lowering times of the opener are noticeably
slower, check the inline filter and clean if needed. See Fig-
ure 5-1.
