fi g.16
Once these preliminary operations have been accomplished (cou-
pling of 3-point hitch to the tractor and cardan shaft engagement),
connect the hydraulic system (Fig. 19) to the tractor.
This will enable the harrow to accomplish its various movements,
i.e.:
- The pipes of the two hydraulic cylinders «A» to open (work
position) and close (transport position) the two transmission units;
- The pipes of the two hydraulic cylinders «B» to regulate the rear
rollers that establish the work depth.
Note: The cylinders «C» that operate the closing clips are
controlled in sequence with the cylinders that control the units.
A specifi c control is therefore not required.
Recognizing the pipe functions
All hydraulic pipes on the machine have recognition stickers as
indicated in Fig. 19:
1: Rear roller lowering.
2: Rear roller lifting.
3: Vertical closing of side units.
4: Horizontal opening of side units.
NOTE: The two cylinders «A» (Fig. 19) are equipped with an block
valve which acts if a pipe breaks.
WARNING
Check the hydraulic pipes frequently and replace them whe-
never they show signs of wear or if small cracks form in the
rubber.

4.8 METHOD OF USE

Sit in the steering seat of the tractor and check that there are no
other persons or animals in the vicinity of either the tractor or
machine.
The folding machine has been designed for use by a single
operator in order to prevent accidents in the case of incorrect
manoeuvres.
When using the implement for the fi rst time, check that the
machine and tractor are compatible with each other. Check
the total weight and weight on each axle. Particularly check
that the percentage of residual weight on the front axle of
the tractor complies with the Highway Code prescriptions.
If necessary, weight the front and check again. Proceed as
described below to transfer the machine to the place of work:
