CAUTION: When using the synchronized PTO and if
you are forced to reverse once or several times, re-
member that the driveline inverts its spinning direc-
tion. Thus, with certain implements, it is advisable to
disengage the PTO when reversing in order to avoid
major damage (lever 2, position N).

WARNING: Danger of entanglement. Keep well
away from spinning shafts. Take care NOT
to remain caught up by the PTO driveline.
Keep all the guards mounted at any time
on the transmission shafts of the tractor or
implements.
WARNING: High-inertia implements do not
become stationary immediately when PTO
is disengaged. Allow sufficient time for
implement to «run down» to a halt before
cleaning or adjusting.

WARNING: External controls must be operated
at a safe distance, standing on one side out-
side the tractor and out of the overall width of
mudguards. It is expressly forbidden to ope-
rate the controls from the rear of the tractor
or standing on the inner side of wheels. [4.2.b]
NOTE: For a table of the revolutions of the synchronized
power take-off output shaft for each revolution of the
rear wheels, see the "Technical specifications" Section.
