• MAINTENANCE SECTION
General rules
It’s imperative to execute every maintenance operation with the machine completely still, even when undoing any elemento f
the hydraulic circuit.
“Warning!
Before any intervention is made, the maintenance person must take the key out of the ignition, after having censure that the motor is
stopped, and disconnect the drive shaft coupling from the power drive of the tractor. Ony in this way can it be certain that the
machine cannot set off unexpectedly while the maintenance person finds him/herself in position of risk.
During maintenance or replacement of hydraulic components, particular attention should be paid to avoiding the introduction of any
foreign object, however small into the circuit which may cause malfunction and compromise the safety of the machine.
Excepting particular demands maintenance must always be carried out with the tools of the machine in resting position and after the
pressure of the oleodynamic accumulators/hydraulics has been released. ”
“Warning!
Avoid executing any operation with bare hands.
”
“Warning!
In the case of any maintenance operation that may need to be done whil one or more functions of the machine is active, precise and unbreakable
imperatives must be adhered to in that:
There should always be at least two persons present: the operator who has the function of supervising the security of the person working and the
maintenance engineer.
”
The operator who is at the commands of the machine and the maintenance engineering should be able to see each other at all
times in order that communication between them will be easy and unequivocal.
The operator acts in accordance to orders given him by the maintenance enginer.
Before changing from a still acivity to a moving activity the maintenance engineer should remain in a position of safety and
only draw closet o the moving parts after havingsecured assurance that his/her rodersi have been received exactly by the
operator. The maintenance should always be done in adeguate light.
The maintenance engineer should be informed of the exact function and movement of every part of the machine.
Periodic checks
Check all parts of the machine daily, in particolar check the state of wear of the blades.
“Warning!
Broken or excessively worn blades must be replaced.
”
“Warning!
The lack of one or more blades can cause a rapid deterioration of the rotor and cause vibrations Any discrepai must be rectified immediately
otherwise the safety conditions of the operator and the machine may be placed in jeopardy..
”
Make a daily check of the sate of wear of the blades. Clean them often when the vegetation is damp.
For the replacement of the blades It will be necessary:
- To lift the machine by means of the 3 point attachment of the tractor.
- To support the machine on props or security block stop prevent a possible collapse
of the lifting mechanism
- Replace the worn blade(s) and fix with nut and bolt using a torque key.
- It’s advised, in order to retain a perfect balance of the rotor, to replate the
diametrically opposite blade
also.
The rotor’s protective safety guards should always be kept in good condition.
A safety guard that is broken, bent or excessively worn must be replaced.
In order to replace it, it will be necessary:
a. to take off the cotter pin (A) indicated in the figure on the right
b. wind off the rod supporting the safety guard
c. replace the safety guard with the replacement
d. refit the whole shaft, blocking the rod with the security cotter pin that was removed.
