Maintenance
Bio-degradable hydraulic oil
The hydraulic system can also be operated with a
synthetic ester based biodegradable hydraulic oil.
The biologically quickly degradable hydraulic oil
Panolin HLP Synth.46 meets all demands of a
mineral oil based hydraulic oil according to
DIN 51524.
In hydraulic systems filled with Panolin HLP
Synth.46 always use the same oil to top up.
When changing from mineral oil based hydraulic
oil to an ester based biologically degradable oil,
you should consult the lubrication oil service of the
oil manufacturer for details.
Caution
!
Check the filter more frequently after this
change.
Perform regular oil analyses for content of wa-
ter and mineral oil.
Replace the hydraulic oil filter element every
500 operating hours.
Gear oil
For the gearboxes use only ,ulti-purpose gear oils
ISO VG 220 of API-GL5-class with a minimum vis-
2
cosity of 20 mm /s at 100 °C.
This is a hypoid lubricant of highest quality class
for extremely loaded transmissions.
The additives in this oil ensure low wear lubrication
under all operating conditions.
Exciter shaft oil
For the exciter unit use a fully synthetic gear oil
SAE 75W-90, API GL5.
Lubrication grease
For lubrication purposes use an EP-high pressure
grease, lithium saponified (penetration 2), acc. to
DIN 51502 KP 2G.
