NOTICE!
Components may get damaged!
– Do not use low-ash engine oils for the exciter
shaft housing.
8.2.4 Hydraulic oil
8.2.4.1 Hydraulic oil
The hydraulic system is operated with hydraulic oil HV 32 (ISO)
with a kinematic viscosity of 32 mm
2
/s at 40 °C (104 °F).
When refilling or changing oil, use only hydraulic oil type HVLP
according to DIN 51524, part 3, or hydraulic oil type HV according
to ISO 6743/4.
The viscosity index must be at least 150 (observe information of
manufacturer).
8.2.4.2 Bio-degradable hydraulic oil
The hydraulic system can also be operated with a synthetic ester
based biodegradable hydraulic oil.
The biodegradable hydraulic oil Panolin HLP Synth. 46 or
Plantohyd 46 S meets all the requirements of a mineral oil based
hydraulic oil according to DIN 51524.
In hydraulic systems filled with biodegradable hydraulic oil, always
use the same oil to top up and do not mix oil types.
When changing from mineral oil based hydraulic oil to an ester
based biologically degradable hydraulic oil, you should consult the
lubrication oil service of the oil manufacturer, or our customer
service for details.
NOTICE!
Danger of damage to the hydraulic system!
– After the changeover check the hydraulic oil fil-
ters increasingly for contamination.
– Have regular oil analyses performed regarding
the water content and mineral oil.
– Replace the hydraulic oil filter at the latest after
500 operating hours.
