TROUBLE SHOOTING
During work several problems can happen:
Unusual noise
While working, if the machine made unusual noise, the operator must stop it immediately
and follow next instructions:
• Check for broken/bent parts.
• Check for correct oil level in the gearbox case.
When present incorrect oil level (see chapter on maintenance), the gears of the gearbox are
not lubricated correctly, and if continue to rotate, would determine a significant increase in
oil temperature. If continue working in this condition will quickly take to damage gear
bearings with consequent blocking of the PTO shaft.
•
Check knives conditions.
If one of the knives is broken or excessively worn, continuing to rotate in short time takes to
damage one of the two bearings (or both) of the shaft in which the knife is fixed. The shaft
begins to oscillate producing great vibration, and in short time finishes to damage the weld-
ings of the frame itself.
• Check condition of the bearings that support the rotor shaft hubs.
As a result of inadequate lubrication (see chapter on maintenance), it is possible that a bear-
ing of one of the rotor shaft hubs has been damaged. The rotor shaft begins to oscillate caus-
ing excessive vibration of the frame, and in short time causing damage of its weldings.
