For trouble-free operation of
the hydraulic system, an oil
with a viscosity suitable for
the climate / seasonal condi-
tions in where the vehicle is
used should be used.
Failure to use hydraulic oil
with a viscosity suitable for
climate / seasonal conditions
in the hydraulic system will
cause temporary or perma-
nent damages and functional
working problems.
In cases where the type of
hydraulic oil used in the vehic-
le needs to be changed, the
system must be cleaned
carefully.
8.15.1. Mixing Hydraulic Oils
Hydraulic oils cannot be mixed, or can
be mixed with each other only condition-
ally. When oils of various manufacturers
or of various types are mixed, sludge
and sludge formation can be encoun-
tered. These can cause malfunction and
damage to the hydraulic system. There-
fore, there is no guarantee for the use of
mixed oils. The relevant mineral oil man-
ufacturer should be consulted regarding
the miscibility of hydraulic oils.
Before using other oil types,
make sure that these oils have
the same characteristics as
the oils given in the Table. Ot-
herwise, wash the system
carefully.
The use of incompatible oils
will void all warranties on
hydraulic system
components.
The use of incompatible oils
can cause the steering and lift
cylinders to be suddenly da-
maged and lose their function.
