See the section "Replacing gaskets on tilt cylinder"
Replacing the crackerboard cylinder (green)
The machine is extended to the
working position, the wheels are
raised so that the two cross-kill roll-
ers are resting on the ground. The
crackerboard tines (A) are then low-
ered 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 ap-
prox. 30 seconds until the oil circulates in all the series-connected cylinders to
the crackerboard.
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 com-
pressible. A section can therefore swing out very quickly if air bleeding is not
performed correctly. This represents 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.
