2.4 CONNECTIONS
- At maximum overlap (with the drive shaft compressed),
there must be a safety gap of B = 20 mm to prevent the
tubes striking the jaws.
- At maximum extension, there must be a tube overlap of A
= 330 mm.
- If the above conditions are not met, shorten the tubes and
their guards by the same length.
- Round off and clean the tubes and grease the inside of the
outer tube.
To avoid the risk of a serious accident,
make sure that the universal drive
shaft guards are properly fitted and
prevented from rotating by the special
chains.
On the machine side, fasten the chain
to the ring (1) located on the header
retaining disc on the gearbox.
Replace any worn or damaged guard
immediately.
On unhitching the machine from the tractor, the drive shaft must always be rested on the support on
the machine tow bar. This support must be folded away when the machine is hitched to the tractor.

2.4.1 Hydraulic
When using the machine with tractors with an oil flow rate in excess of 60 l/min, a flow dividing system
must be provided to prevent the circuit from overheating.
If your tractor is equipped with a closed-centre hydraulic circuit, make
a return to the filter (except on machines equipped with an optional
hydraulic power unit).
