19. Using the rams (pos. 5), swing the side sections in until they hit the stop/
transport bearing. Keep an eye on the hydraulic hoses.
Take care not to get trapped.
20. Using the large rams (red hoses), lower the side sections into the transport
bearing.
Connect the roller to the drawbar of the tractor . This should be approx. 45
cm above the ground so that the drawbar is horizontal in working position. If
the tractor's drawbar is lower, the drawplate on the roller can be fitted
underneath the drawbar.
Remember to secure the drawbar pin.
Connect each of the two sets of hydraulic hoses to its own double-acting
hydraulic tap. All the hoses have a ½" male connector. If your tractor is not
equipped for this, your dealer will be able to help.
A maximum pump pressure of 160 bar is required.
Defective hoses must be repaired or replaced immediately.
A broken hose can in bad cases cause personal injury or mechanical damage
to the roller in adverse circumstances.
The roller must always be operated from the driver's seat and there must be
no-one else in the vicinity of the roller.
The changeover from transport position to working position should take place
while stationary on approximately level ground with the tractor almost idling.
It is extremely dangerous to modify the hydraulic system, as the circuit
contains several safety components.
First raise the side sections clear of their transport bearing
with the large rams (red hoses). Swing the side sections
out jointly, with the swing rams (blue hoses pos. 5), and
then push the outer sections out into working position.
Hydraulic valves on the central section ensure that this is
done in the correct sequence through operation of the
valve connected to the blue hoses.
