LOR
Cutter-Mixer-Feeder requires that each
operator reads and understands all the operating procedures and all related safety
precautions outlined in this section. A pre-operation checklist is provided for the operator. It
is important for both the personal safety and maintaining the good mechanical condition of
the machine that this checklist is followed.
Before operating the machine the following areas should be checked off:
1. Lubricate the machine as per Maintenance Schedule.
2. Use only a tractor of adequate power and capacity to operate the machine.
3. Ensure that the machine is properly attached to the tractor. Be sure that the retainer is
installed in the drawbar pin and the safety chain is attached.
4. Check the hydraulic system. Be sure that the hydraulic reservoir in the tractor is filled to
the required specifications.
5. Check the oil level and condition in the planetary gearbox. Be sure they are within the
proper levels. Be sure there are no leaks on the gearbox. Stop leaks before continuing.
6. Inspect all hydraulic lines, hoses, fittings, and couplers for tightness. Use a clean cloth
to wipe any accumulated dirt from the couplers before connecting to the hydraulic
system of the tractor.
7. Check the tires to be sure that they are inflated to the specified pressure. Torque wheel
nuts to 180 ft. lbs.
8. Check that the auger rotates freely. Remove all string, twine, or other entangled
material.
9. Check that the PTO driveline is locked to the tractor shaft and the guard is chained to
the frame.
10. Close and secure all guards and safety devices.

Top up tractor oil reservoir if required.
B. After operating for ½ hour:
•
Check that all bolts and fasteners are all tightened properly. (See Torque Spec.)
•
Check that all wheel nuts are tight and torque to 180 ft. lbs.
