MAINTENANCE INSTRUCTIONS
Most of the works of planned technical
maintenance can be done by the driver
or user of the tractor himself/herself. If
you do not have the corresponding tech-
nical equipment, turn to a specialized
garage for the more difficult steps.
All the works related to the clean-
ing, greasing and adjusting the
tractor or articulated machines can
be done only with tractor and other
moving parts at standstill, apart
from the brake, charging and hy-
draulic controls.
