On the central section and drawbar yellow sitckers showing a lifting hook
indicate where to hook onto for effective lifting.
Should be carried out in a workshop. See
Fitting:
Fig. 7 and 8.
A level floor, an approved crane cabable of lifting a minimum of 1000 kg and a
hydraulic pump with a single-acting and a double-acting take-off is required. It must
be able to exert a pressure of at least 170 bar.
Install the central section vertically on the roller rings and wheel hubs. Fit the
drawbar with the pin in position 15, remember the split pin.
Fit the tilting ram, position 59.
Fit and adjust the support so that the height of the drawbar is approx. 40 cm.
Connect the tilting ram to a single-acting hydraulic take-off; the hose is marked
white.
Lift one of the wheel hubs with the crane whilst carefully allowing the oil to drain out
ofthe ram
This will cause the central section to assume a horizontal position.
Lift each side section into position with the crane hooking onto it as described under
"handling". Secure the side sections with the pins, pos. 35, which are in tum secured
with the screws, pos. 36.
Connect the hoses to the folding ram to a double-acting take-off.
Push the folding ram out almost to their full extent and fit, making sure that the
hoses do not cross.
Fit the wheels.
Apply pressure in order to push the folding ram all the way out.
Carefully rock the roller upwards by applying pressure on the single-acting ram,
making sure that all the hoses are able to move freely.
Carefully retract the roller with the double-acting valve, keeping an eye on the hoses.
Ease the pressure on the single-acting ram so that the side sections drop down into
their transport bearing.
Secure the hoses to the folding ram with the hose clips and self-tapping
screws.
Fold the roller in and out a couple oftimes. Keep an eye on the hoses. The folding
rams are throttled op prevent too fast a movement. This is not of crusial
importance but it may give rise to a whistling sound in the pressure valve on the
hydraulic pump.
Tighten all screws securely, including hub nuts.

The roller sections are swivelled back to the transport position in the reverse order
to extension.
