Maintenance Instructions - Zetor PROXIMA POWER Z90 2012 Operator's Manual

The driver or user of the tractor can do
most of the planned maintenance work
by himself. However, if you do not have
sufficient technical equipment, entrust
the execution of more complicated tasks
to a specialized workshop.
All the work related to the clean-
ing, lubrication and adjust-ment
of the tractor or attached imple-
ments may only be perfor-med
after stopping of the engine and
other movable parts except the
brake control, charging and hy-
draulic system.
