Fit new or repaired cylinder
After the wheel cylinders are fitted, they are actuated until they show a slight
travel. Reverse cylinder until it returns to start position. Move cylinder back-
wards and forwards several times.
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.
Replacing gaskets on the wheel cylinder
See the section "Replacing gaskets on tilt cylinder"
Replacing the harrow hoist cylinder (white valve block no. 3).
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
harrow arms (A) are then lowered so
that the harrow tines (B) rest on the
ground. The harrow hoist cylinders
are then depressurised (A).
