6.2. HYDRAULIC FLUIDS
A wide range of standard hydraulic fluids can be used with the DYNASET hydraulic
equipment. Depending on the operating temperature, the following mineral
hydraulic oils are recommended:
MINERAL HYDRAULIC OIL OPERATION TEMPERATURE UP TO
ISO VG 32S 60 °C
ISO VG 46S 70 °C
ISO VG 68S 80 °C
NOTE!
Recommended oil viscosity is between 10 to 35 cSt when operating at
normal operating temperature.
Synthetic and bio-oils can also be used if their viscosity characteristics and
lubricating efficiency are similar to the mineral oils. Automatic transmission fluids
and even engine oils can be used, provided that they are allowed to be used in
hydraulic system of your base machine.
