all the nuts fully.
See fig. 10. Attach the T-piece (pos. 1) to the front cross tube of the main
frame straight in front of the left-hand longitudinal tube. Run the hoses out to
the rams and attach them with the self-tapping screws and hose clamps
(pos.2). Use a 4,4 mm drill to drill the screw holes.
Take the middle hose along the left-hand tube, use clamps pos. 2.
Take it further in a neat arc and fasten it to the drawbar. It ends at the left-
hand connection on the hydraulic block. Attach the connecting hose to the
right-hand connection and bring it, together with the other hoses, to the
tractor.
Fig. 10:
Connect the green connecting hoses to a single-acting valve on the tractor.
Two single-acting and one double-acting take-off are normally required
to operate the complete roller with levelling bar. The job can be done with two
double-acting valves, one of which must have a floating setting. If this method
is used, the white and green hoses must be connected to the valve with
the float setting. The green hose must be positioned so that the levelling bar
moves when the operating handle on the tractor is moved towards the float
setting in order to raise the levelling bar without actuating the roller lifting
cylinder.
Fold up the roller carefully, ensure that the hoses are not squeezed or stretched
while the roller is being closed up.
With the roller opened out, lower the levelling bar until the ram is fully
extended.
Check that the pressure gauge is registering. With the levelling bar in this
