After fitting, the harrow hoist 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.
Ensure no personnel are within the extension radius of the side sections.
