Before installing a bypass through the blind at the hydraulics block of the spreader, it is to
be ensured at the tractor and the spreader that the hydraulic system is functioning correctly:
1. Tractor
o
Stand-by pressure (for most tractors, it is between 20 and 25 bar; please
note that, with units of some manufacturers, the activation of the control
units or the automatic steering increases the stand-by pressure to up to
50 bar.
o
Size of the free return flow of the tractor is sufficient, return flow filter is clean
o
LS line closed correctly; in case of retrofitted power-beyond solutions, please
check that the replacement valve has been mounted correctly
o
Sufficient hydraulic power
o
Impacts due to steering movements or other consumer units cannot be
compensated
2. Spreader
o
Proportional valve vented
o
Pressure scales not contaminated (spreader does not reach speed on one
side and/or runs noisily)
o
LS screw completely turned in
o
Speed sensors in an impeccable condition
o
Cabling of proportional valves and sensors is in an impeccable condition
