1. Connect all hydraulic and electrical connections between the implement and machine as
shown in sections 5.3 and 5.4 .
2. Loosen the back-up nut & turn the down force valve anti-clockwise, until no spring pressure is
felt (5mm Allen key & 17mm spanner required)
3. Start the tractor and set the engine rpm to operating speed.
4. Adjust the oil flow that will supply the down force circuit to the minimum value.
5. Engage the hydraulic spool (tractor) in to "Constant Pump", slowly increase the flow control until
the Down Force gauge shows 15 bars.
6. To increase the downforce, turn the valve clockwise to the desired pressure, lock the valve in
position with the back-up nut.
IMPORTANT: The usage of high downforce pressure can change the sowing
depth of the machine, therefore it may be necessary to readjust the depth
settings.
IMPORTANT: Usage of excessive down pressure will unnecessarily accelerate
the mechanical wear rates of some components, as well as having a detrimental
impact on the quality of the seeding furrow (Excessive compaction upon closing)
