Operating Instructions
5. Servicing and Maintenance
If the tine circuit should need setting the fol-
lowing procedure should be followed (an as-
sistant will be required):
1
First locate the manifold block; it is lo-
cated at the front of the Solo on the right
hand side of the machine, just under the
main chassis.
2
Locate the valve on the rear face of the
block and undo the lock nut. Using a
4mm allen key turn the valve all the way
clockwise then turn it anticlockwise 2 full
turns.
3
Locate the valve on the far side of the
block; undo the lock nut and turn the
valve all the way clockwise.
4
Locate the valve on the near face of the
block, undo the lock nut and turn the
valve all the way anticlockwise.
5
Start the tractor and put the spool that
controls the tines into the float position.
Both the gauges will go to zero and the
tines will go down. This indicates that
the system is depressurised.
6
Now get someone to pressure the tines
down. Whilst they are being pressured
down, turn the valve on the near side of
the block slowly clockwise. The pres-
sure on the lower gauge will start to rise.
Turn the valve until you reach approxi-
mately 80 to 90 bar (the pressure on the
upper gauge will now be reading ap-
proximately 10 to 15 bar). Lock off all
the valves. The tine circuit is now set.
