5.2. Recommended Hydraulic Oil and Lubricant
For perfect function of the electric stacker we recommend to use a hydraulic oil respectively a lubricant as
per the below table. These special oils fulfil best the technical requirements with regard to viscosity (walk
penetration) and pour point.
The lubricants are based on ambient temperatures of - 10° up to + 40°C.
In case of extreme temperatures please contact us or the "Technical Services" of the below-listed mineral oil
companies.
Please also observe our instruction for the operation at low temperatures (see 8.)
