17 – HYDRAULIC COLLECTOR DUMPING (OPTION)
Use
See chapter 10.
Maintenance
No particular maintenance is required. Just periodically check the oil quantity in the circuit as already described in the
previous chapter.
Oil quantity and quality: see chapter 21.
18 – HYDRAULIC COLLECTOR ELEVATOR (OPTION)
Technical features
The hydraulic collector elevator is controlled by the pump which, by acting on a pair of hydraulic pistons hinged to the
base of the uprights, allows the collector to be lifted whilst maintaining its original horizontal position.
Another pair of hydraulic pistons dumps the container independently from the elevator positions.
Use
See chapter 10.
Maintenance
No particular maintenance is required. Just periodically check the oil quantity in the circuit as already described in
chapter 16.
Oil quantity and quality: see chapter 21.
Specific maintenance consists of periodical greasing (after about 50 hours) by means of the six grease nipples located
a)
on the lower and upper hinges of the two lifting system rods.
b)
On the two hinges of the grasscatcher supporting frame.
c)
On the hinges of the four pistons.
The unidirectional valve hole (side picture No. 1) may
become clogged by impurities in the oil. In this case the
elevator will be inhibited during descent phase.
Proceed in the following way to restore correct operation:
1) Remove the valve from the pipes to which it is
connected, making note of the connection direction. The
tip of the cone point towards the pipe that leads to the
distributor. Pay attention to the sudden descent of the
attachment as soon as the valve is removed.
2) Clean with compressed air (or gasoline [do not use
unleaded fuel for cleaning] if necessary) in order to
eliminate the clogging impurities.
3) Remount the valve in its original configuration
