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 the track loosener cylinder (white valve block no. 2).
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
track loosener tines (A) are then
lowered so that the cylinder (B) is as
short as possible and the track loos-
ener tines rest on the ground. The
track loosener cylinder is then de-
pressurised (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 track eliminator is actuated until the cylinder shows a slight
travel. Reverse cylinder until it returns to start position. Move cylinder back-
wards and forwards several times.
