Prior to long transport journeys or when filling, close both shut-off valves in the
hydraulic circuit to prevent subsequent opening of the metering slides, should
oil inadvertently escape through the control valves.
If the spreader is to be stored for any length of time, it is recommended that the
metering slides are left open so that spring tension is not weakened. Proceed
as follows :
1.
Hydraulically close the metering slides
2.
Adjust positioning lever stops to their highest scale level.
3.
Open metering slides.
5.8.2 Double acting hydraulic metering control for MDS 55 D
/ 65 D / 85 D / 735 D / 935 D
The metering slides operate with two double acting hydraulic cylinders.
Oil pressure closes – Oil pressure opens
Connecting the hydraulic metering slide control:
The following hydraulic valves are needed on the tractor :
Two double acting control valves
5.8.3 Single acting hydraulic metering control with double
acting mechanism for MDS 55 R / 65 R / 85 R / 735 R /
935 R
The MDS 55 R / 65 R / 85 R / 735 R / 935 R metering slides operate with two
single acting hydraulic cylinders complete with externally mounted return
springs.
Oil pressure closes – Spring tension opens
Connecting the hydraulic metering control:
The folowing hydraulic valves are needed on the tractor:
•
One
single acting or one double acting
valve with free return.
Attach the holder brackets for the shut-off valves to a suitable place on the trac-
tor.
Prior to long transport journeys or when filling, close both shut-off valves to the
double acting mechanism to prevent subsequent opening of the metering slides,
should oil inadvertently escape through the control valves.
If the spreader is to be stored for long periods, it is recommended that the mete-
ring slides are left open so that spring tension is not weakened. Proceed as fol-
lows:
1.
Hydraulically close the metering slides.
2.
Adjust positioning lever stops to their highest scale level.
3.
Open metering slides.
