ROLLOMAXIMUM XL

The machine is extended to the work-
ing position, the wheels are raised so
that the two cross-kill rollers are rest-
ing on the ground. The crackerboard
tines (A) are then lowered so that they
rest on the ground. The cylinder is then
depressurised (B).
1.
Disconnect hoses from cylinder
2.
Support cylinder
3.
Remove split pins from pins, remove pins
4.
Remove cylinder
5.
Fit new or repaired cylinder
After fitting, the harrow hoist is actuated until the cylinder shows a slight travel.
The cylinder is then actuated until it is retracted. Continue this for approx. 30 sec-
onds until the oil circulates in all the series-connected cylinders to the cracker-
board.
If cylinder is not bled correctly as described above, there is a risk that part of the
machine can suddenly move much quicker than normal, and before the tractor
driver can prevent it. This is because air (unlike oil) is compressible. A section can
therefore swing out very quickly if air bleeding is not performed correctly. This rep-
resents a major risk of injury to personnel and of damage to the machine.
Ensure no personnel are within the extension radius of the side sections.
