elements for damages.
• Check that the hose is fitted correctly to the air unit and to the head
part connector.
• The air pressure in the distribution system must be in the range
300 – 1000 kPa.
• Check that the air flow in the hose is sufficient.
• Ensure that air is supplied into the head part breathing zone.
