53 Maintenance and Lubrication
Maintenance and Lubrication
Proper servicing and maintenance is the key to
long implement 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.
You may be severely injured or killed by being crushed
under the falling implement. Always have transport
locks in place and frame sufficiently blocked up when
working on implement.
Escaping fluid under pressure can have sufficient pres-
sure 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 pa-
per 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.
1. After using drill for several hours, check all
bolts to be sure they are tight.
2. Lubricate areas listed under “Lubrication”,
page 64.
3. Adjust idlers to remove excess slack from
chains. Clean and use chain lube on all roller
chains as needed.
4. Check tire pressure weekly. Inflate tires as
specified on “Tire Inflation Chart”, page 107.
5. Replace any worn, damaged or illegible safe-
ty decals. Order new decals from your Great
Plains dealer. Refer to “Safety Decals”, page
7.
