7 Maintenance
Important information on operation with biodegradable oils
• Use only the tested and approved biodegradable hydraulic fluids
– see "Fluids and lubricants" on page 7-14 . Always contact the
manufacturer for the use of products other than those that have been
recommended. In addition, ask the oil supplier for a written declaration
of guarantee. This guarantee is applicable to damage occurring on the
hydraulic components that can be proved to be due to
the hydraulic fluid.
• When biodegradable oil is being refilled, use the same type of
biodegradable oil. In order to avoid misunderstandings, a label
providing clear information is located on the hydraulic oil reservoir
(next to the filler inlet) regarding the type of oil currently used! Replace
missing labels!
Mixing two different biodegradable oils can worsen the quality of one of
the oil types. Therefore, when changing biodegradable oil, ensure that
the remaining amount of the original hydraulic fluid in the hydraulic
system does not exceed 8% (manufacturer indications).
• Do not add mineral oil – the content of mineral oil should not exceed
2 % by weight in order to avoid foaming problems and to ensure
biodegradability.
• When running the machine with biodegradable oil, the same oil and
filter replacement intervals are valid as for mineral oil
– see "Maintenance plan" on page 7-6 .
• The condensate in the hydraulic oil tank has to be drained by
an authorized specialist workshop every 500 hours of operation, and in
any case before the cold season starts.
The water content must not exceed 0.1% by weight.
• The instructions in this Operator’s Manual concerning environmental
protection are also valid for the use of biodegradable oil.
• If additional hydraulic attachments are installed or operated, use the
same type of biodegradable oil for these attachments to avoid mixtures
in the hydraulic system.
Information
Subsequent change from mineral oil to biodegradable oil must be
performed by an authorized service center or by a dealer.
