Maintenance Instructions - Zetor FORTERRA HSX 120 Operator's Manual

The driver of the tractor can do most of
the planned maintenance work by him-
self. However, if you do not have suffi-
cient technical equipment, entrust the
execution of more complicated tasks to a
specialized workshop.
All the work related to the clean-
ing, lubrication and adjustment of
the tractor or attached imple-
ments may only be performed af-
ter stopping of the engine and
other movable parts except the
brake control and charging.
