Maintenance
Important information for the use of biodegradable oil
• Use only the biodegradable hydraulic fluids which have been tested and approved by
Neuson Baumaschinen GmbH. Always contact Neuson Baumaschinen GmbH for the
use of other products which 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, which can be proved to be due to the hydraulic
fluid.
• Use only biodegradable oil of the same type for filling up. In order to avoid
misunderstandings, a label providing clear information is located on the hydraulic oil
tank (next to the filler inlet) regarding the type of oil currently used! Replace missing
labels!
The joint use of two different biodegradable oils can affect the quality of one of the oil
types. Therefore, make sure the remaining amount of initial hydraulic fluid in the
hydraulic system does not exceed 8 % when changing biodegradable oil (manufacturer
indications).
• Do not fill up with mineral oil – the content of mineral oil should not exceed 2 % in order
to avoid foaming problems and to ensure biological degradability.
• When running the machine with biodegradable oil, the same oil and filter replacement
intervals are valid as for mineral oil
– see chapter 5.15 Maintenance plan (overview) on
page 5-35.
• Always have the condensation water in the hydraulic oil tank drained by an authorised
workshop before the cold season. The water content may 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 mounted 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 carried out by an
authorised workshop or by your Neuson partner
