preventing anti-scratch).

5. Fit new or repaired cylinder
After fitting the tilt cylinder, it 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.
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.
