CAUTION
For those loaders which are fitted to run with
biodegradable hydraulic oil (ester-based synthetic
hydraulic oil of viscosity class ISO VG 46 VI
> 180 – designation can be found on the hydraulic
oil reservoir and on the dashboard), only this type
of oil may be used for oil changes.
Mineral and biodegradable hydraulic oils must
never be mixed!
Biodegradable hydraulic oil must be changed
every 1000 operating hours.
Changing the oil type from mineral oil to
biodegradable oil must be performed according to
the VDMA 24 569 conversion guidelines.
