Important information on the use of biodegradable oil
• Use only the biodegradable hydraulic fluids which have been tested and approved by
Wacker Neuson. Always contact Wacker Neuson for the use of other products that
have not 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
• Use only biodegradable oil of the same type for adding oil. In order to avoid misunder-
standings, 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, ensure that the remaining amount of initial hydraulic fluid in the hydraulic
system does not exceed 8 % when changing biodegradable oil (manufacturer indica-
tions)
• 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 biological degradability
• When operating the vehicle with biodegradable oil, the same oil and filter replacement
intervals are valid as for mineral oil
– see Maintenance plan DT10 on page 5-37
• Always have the condensation water in the hydraulic oil reservoir drained by a Wacker
Neuson service center before the cold season. 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.
Subsequent change from mineral oil to biodegradable oil must be performed by a
Wacker Neuson service center or by your Wacker Neuson distributor.
