Maintenance
Before proceeding with any maintenance work on the machine, it is
essential to carry out the following operations:
•
never carry out any work on the machine while it is in operation
•
the tractor Pto must be disengaged, the engine switched off and
the key removed from the starter switch
•
the machine and the tractor must be secured in a stable position;
the tractor's hydraulic linkage control must be locked to prevent it
being lowered accidentally.
After the first two (2) hours of operation, check the tightness of the
bolts and screws; also check their tightness each day before starting
work.
We recommend that you use only original replacement parts.
Each day, before starting work, check the oil levels in the gearbox and
the grease in the transmission casing.
Lubricate with multipurpose grease the levelling bar height adjuster
(every 50 hours), and the bearings of the rollers (every 10 hours).
Lubricate the drive shaft following the indications given in the figure
below.
