Synthetic esters
An environmentally compatible hydraulic
fluid is extremely important. Besides the
operating conditions, service life factor (oil
change interval) and the high price difference,
the economic aspect must also be taken into
account. Compare the price in relation to the
downtime factor and disposal.
Observe that for synthetic esters there are
differences in the basic structures of oleic
acid ester products and carboxylic acid ester
products:
oleic acid-based synthetic esters age faster
R
the operational effectiveness of carboxylic
R
acid-based synthetic esters is virtually
unlimited, provided the degree of contam-
ination does not require a premature oil
change to be performed
Brands of environmentally-compatible
hydraulic fluids
H
Environmental note
Environmentally compatible hydraulic fluids
must be separately stored, collected and dis-
posed of in accordance with waste manage-
ment laws.
Optional equipment code HB2: the hydraulic
system is filled at the factory with RIVOLTA
S.B.H. 23.
Optional equipment code H97: the hydraulic
system is filled at the factory with carboxylic
acid ester, Panolin HLP Synth 46.
Have the hydraulic fluid replaced regularly at
a qualified specialist workshop. You can find
the intervals for hydraulic fluid change and
filter change in the maintenance booklet.
Mixing similar oil types can affect operational
effectiveness and biodegradability to an
impermissible degree. Mixing mineral oils and
environmentally-friendly hydraulic fluids is
not permissible.
The hydraulic system is filled with mineral oil
as standard, unless the environmentally com-
patible hydraulic oil is expressly ordered as an
option (code HB2 or code H97).
Diesel fuels

Important safety notes

G
WARNING
Fuel is highly flammable. Improper handing of
fuel creates a risk of fire and explosion.
Avoid fire, naked flames, smoking and creat-
ing sparks under all circumstances. Switch off
the engine and, if applicable, the auxiliary
heating before refuelling.
! If you are using drums or canisters to
refuel the vehicle, you should filter the fuel
before adding it.
This will prevent malfunctions in the fuel
system due to contaminated fuel.
! Only refuel using commercially available,
sulphur-free diesel fuel that conforms to
the European standard EN 590 as of 2010,
et seq. (max. 0.001% sulphur by weight).
The following fuel types are not permitted:
sulphurous fuel with a sulphur content
R
greater than 0.001% by weight
marine diesel fuel
R
aviation turbine fuel
R
heating oils
R
fatty acid methyl ester FAME (bio-diesel
R
fuel)
These fuel types cause irreversible damage
to the engine and BlueTec
aftertreatment, as well as also significantly
reducing the expected service life.
! A higher fuel sulphur content accelerates
the ageing process of the engine oil and can
damage the engine and exhaust system.
Fuel grade
Before delivery, the fuel sulphur content is set
to <0.001% sulphur by weight (10 ppm).
