After fitting, the harrow hoist is actuated until the cylinder shows a slight travel.
Reverse cylinder until it returns to start position. Move cylinder backwards 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 compressible. A section can
therefore swing out very quickly if air bleeding is not performed correctly. This rep-
resents 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.
