following:
• Hoses at the customer premises cannot be stored more
than 2 years before being discarded or installed on a
machine.
• In-service lifetime of hoses fitted on a machine can never
exceed 6 years, but replace hoses described in "Major
Parts - Periodic Replacement" on page 4-63, every 2
years. Always replace hoses having exceeded the allowed
in-service lifetime irrespective of the external appearance/
wear.
• Always store hoses in a dark place at a maximum of 65%
relative humidity, between 0°C (32°F) and 35°C (95°F) but
as close as possible to 15°C (59°F) and away from copper,
