TROUBLESHOOTING
During work several problems can happen.
UNUSUAL NOISES.
During operations, if the implement produces loud, unusual noises, the operator must
immediately stop it and follow these instructions::
• Make sure there are no broken mechanical parts.
• Verify that the gearbox contains the correct amount of oil.
If the oil level is too low (please see the chapter on maintenance), the gears of the conic
couple are not adequately lubricated and will
overheat the remaining oil if operations
continue. This will rapidly produce damages to the conic couple and its bearings .
• Check knives conditions.
If some of the knives are broken, bent or present excessive wear, the balance of the rotor
will be compromised. During operations, the turning movement of the rotor will produce
vibrations that will inevitably damage and break support bearings and frame welds. To
avoid damages, please replace all the knives at the same time with new, original knives
supplied by the manufacturer
.
• Check rotor support bearings.
As a consequence of reduced lubrication, one of the bearings supporting the rotor may
have broken down. The rotor starts to oscillate producing excessive vibrations against
the frame, producing damages to the welded parts of the frame.
Another cause for damaged support bearings can be the impact with heavy, fixed objects
on the ground such as rocks.
