Never operate the PTO at too great an angle (X = 30° maximum) (fig. B).
These recommendations and adjustments must be respected to avoid damage or
premature wear of the PTO. Repeat these checks when the machine is fitted to any other
tractor.
Only operate the machine at the PTO speed (rotational frequency) indicated on
decal (K) (photo 19). Attach the GMD 801 to the 1000 rpm (min
-1
) PTO.
To avoid accidents which could be serious, make sure that the guards are always correctly
in place and secured with the safety chains (C) (photo 19). Warn or damaged guards must
be replaced immediately.
