On the machines equipped by hydraulic installation must connect the coupling to the tractor.
Be careful that to open or close the hydraulic circuit it's necessary to use the cock (Fig. 10).

ADAPTING THE UNIVERSAL COUPLING
Due to the various positions which the shaft of the power take-off can assume on the different tractors, it
may be necessary to correct the length of the cardan shaft.
This length should be controlled when putting the machine into service for the first time.
Extract the two axle shaft is the cardan and insert them separately. (Eventual free wheel-machine side).
Check that, when the cardan shaft is in minimum extension position (Tedder raised or lower) the tube must
not touch each other on the bottom, but it is necessary to have minimum clearance of 20 mm.
lf necessary, shorten the shafts and the protections.
Before reinserting the two axel shafts, carefully clean and grease the sliding parts. (Fig. 13)
When the cardan shafts is in maximum extension (security disengaged) the tubes must be inserted
minimum 150 mm.
Fix the external protection of cardan shaft by its proper chain. (Fig. 07)
HOW TO USE THE TEDDER
For the machines equipped with movable linkage, insert the lock-pins. (Fig. 16)
Before transport, close the lock-key of cock, that is placed on supple tube of
hydraulic circuit. (Fig. 10)
