9 REPLACING PARTS
Before carrying out any work, it is mandatory to:
- Lower the flail head to the ground
- Disconnect the power takeoff, stop the tractor and take the starting key out
- Wear working gloves
9.1 Flail replacement
When the flails are worn, they must all be
replaced. In case of a partially broken flail, it is
advisable to replace the broken one and the
one diametrically opposite to it, in order to
maintain the balance (see Fig. 37).
9.2 Pipe replacement
- Before working on the hydraulic system, exhaust all pressure, working with the
engine stopped and using all control levers.
- Unscrew the filling cap on the oil tank to avoid the siphon effect, which could
empty the tank.
- Pay particular attention to cleanliness as dirt and dust can cause a great deal of
damage to the hydraulic system.
- Replace any damaged pipes with genuine spare parts, or with others of the same
specification; ensure that they are not kinked or twisted – remembering to check
this throughout the entire cycle of arm movement.
9.3 Pin replacement
- Carry out this operation wit the aid of a lift or hoist, to prevent detached
components falling, and also upsetting the balance of the machine.
- When replacing parts, clean and grease
their housing.
9.4 Oil and filter replacement
ATTENTION: Before doing any work on the
oil tank, SLOWLY UNSCREW THE FILLING
CAP B, to exhaust the pressure (0.4 Bar)
inside the tank.
- After the first 40 hours and then every 300
hours of operation, replace the oil filter (A)
(Fig. 38).
- For the system with the pistons pump,
replace the suction filter D at the same time
as the oil, after having closed the cock E.
