6.5 PTO ROTATION SPEED
To make sure the equipment work as best as it can, it is necessary to assure to the pump unit the correct
number of revolutions, in order to obtain pressure and oil enough to perform all the operations. There-
fore using the tractor PTO, which works at max. 540 r.p.m.,
PTO rotation speed shall NOT EXCEED
540 r.p.m.
A higher rotation speed can irreparably damage the hydraulic circuit components. A lower rotation
speed makes the equipment useless because of the lack of pressure and the consequent lack of power
required to move the tools.
6.6 START UP
If the machine is started for the
fi
rst time or after a long idle time, you just have to follow these
instructions, paying particular attention to the hole coupling cleaning.
~
Start the machine and set the parking brake.
~
Raise the equipment from the ground, run the PTO and bring the tractor engine to its
minimum
r.p.m.
~
Stay in front of the power disc or other tools (
Fig. 11
) and,
only from this position and WITH
THE GREATEST CARE
, operate the sensing device rod in such a way as to simulate an
obstacle during the set of discs advancing. Verify that the set of discs goes along the whole
stroke, i.e. reaches a position, which is parallel to the machine axis. When the sensing device
rod has been released, the set of discs shall go back to its starting position. The set of discs shall
have to move continuously and without jolts or discontinuities, as these are signs of air in the
hydraulic
circuit.
Operate the same control also from the driver's seat.
THE MACHINE STARTING AND START UP SHALL BE PERFORMED BY AUTHORIZED
PERSONNEL AND TRAINED TO THE USE OF THE MACHINE. THE MANUFACTURER
DECLINES ANY RESPONSIBILITY FOR INJURIES TO PEOPLE AND/OR DAMAGE TO
THINGS DUE TO THE NON-OBSERVANCE OF THE PRECAUTIONS IN THIS MANUAL.
