FLAIL MOWER - FMH Series
WARNING
When driving on public roads, reduce your speed, be aware of traffic around you and proceed in
such a way that faster moving vehicles may pass you safely.
6. MAINTENANCE
Proper and regular maintenance ensures a long life of the equipment, avoids failures and saves
time and repair costs.
Periodic inspections and maintenance operations described in this section must be performed by
operator in the times and terms prescribed. Failure to comply with maintenance prescriptions can
compromise the functioning and duration of the machine, and consequently invalidate the
warranty.
The frequency of maintenance indicated refers to normal conditions of use: it must be intensified in
severe operating conditions (frequent stops and starts, prolonged winter season etc ...).
Repairs, maintenance and modifications other than those mentioned in this paragraph should NOT
be performed without consulting the Manufacturer or your Dealer. Manufacturer, as the case, may
give the authorization to proceed with the repair together with all necessary instructions.
Wrong or inappropriate repairs or maintenance may generate abnormal operating conditions,
equipment damage and generate risks for the operator.
AVVERTENZA
For safety reasons, all maintenance operations must be performed with tractor PTO disengaged,
flail mower stopped and completely lowered to the ground or onto support blocks, parking brake
set, tractor engine shut off, and ignition key removed.
IMPORTANT
Respect the environment. Store or dispose of unused chemicals as specified by the chemical
Manufacturer.
6.1. ROTOR TOOLS REPLACEMENT
Frequently check the wear condition of the tools on the rotor (Y blades or hammers) through visual inspec-
tion. The wear of the tools is very variable depending on the type of soil.
Replacement of the tools is necessary when the operator notices increase of power absorption during ope-
rations, or when the blades or hammers dimension is significantly reduced compared to the original.
The use of the machine with tools in bad condition compromises the quality of the work.
Before perform replacement of the blades:
• idle tractor engine, set the parking brake, disengage tractor PTO, and wait for all moving parts to come to
a complete stop;
• place the machine slightly lifted from the ground on safety blocks or mechanical stands;
• lock the control lever of the hydraulic lift of the tractor;
• turn off the tractor and remove the key from the control panel.
To perform the replacement of blades:
• remove the bolt that locks the couple of Y blades (or the hammer) in the rotor. For the Y blades, two
bushing are placed on the bolt to fill the gap between the blades and the holders of the rotor;
• place the new tool instead of the one worn out, and tighten the bolts with washers, referring to the
torque values shown in “Table torques” in the manual. Be sure to install the cutting edge facing in the
direction of rotation of the rotor. For the rotor with Y blades do not forget to place the related
bushings between the blades and the holders.
• repeat the same procedure for all the Y blades (or hammers);
