UNFOLDING THE DRILL
IN FIELD OPERATION
1. Ensure all hydraulic hoses are connected to the tractor spool valves correctly.
DO NOT OPERATE ANY HYDRAULIC FUNCTIONS UNLESS THE FREE FLOW RETURN IS CORRECTLY
INSTALLED. FAILURE TO DO SO COULD RESULT IN DAMAGE TO THE DRILL’S HYDRAULIC SYSTEM WHICH
WILL NOT BE COVERED BY THE WARRANTY.
2. Operate the tractor spool valve to lift the drill (hose marked
II
).
3. Once the drill is raised, operate the spool valve to fold the wings (hose marked
II
). This will ensure that
the steps are fully folded and the drill is lifted clear of its transport hooks.
4. Reverse the drill spool valve to begin lowering the wings, (hose marked
I
) once fully unfolded return
the spool valve to the central position.
5. Operate the tractor spool valve to lower the drill into work (hose marked
I
)
6. Operate the tractor spool to start the fan (hose marked
II
) for safety you should reduce the flow rate
on the tractor spool valve to the minimum setting and then slowly increase the flow rate on the tractor
spool valve to the minimum setting and then slowly increase the flow rate once the fan is running to
achieve a fan speed of 4,000rpm.
OPERATING THE DRILL
To operate the drill use the spool valve to raise and lower the drill in and out of work (hoses marker I & II),
the bout markers (if fitted) and pre emergence markers are controlled by the drill computer, see section
on navigating the control unit.
Ensure the spool valve is operated for long enough to ensure the bout markers (if used) are fully
extended before returning the spool valve to its central position.
Each time the drill is raised both bout markers (if fitted) and the pre emergence markers are also raised
out of work to ensure safe and convenient headland turns.
FOLDING THE DRILL
1.
Stop the fan. The drill will not fold with the fan running.
2.
Operate the tractor spool valve (hose marked
II
) to fully raise the drill.
3.
Operate the tractor spool valve to fold up the wings of the drill (hose marked
II
).
4.
Operate the tractor spool valve to lower the drill into its transport hooks (hose marked
I
) ensure
the depth wheels are fully retracted.
