5.3 - HYDRAULIC OIL
Hydraulic oils must comply with the following requirements :
• Oil filterability must be compatible with absolute filters
• Have properties such as :
• Antifoam and deaeration
• Anti-wear, anti-shear and antioxydant
• Rust and corrosion inhibitors (copper)
The recommended viscosity grades depending on the environmental conditions are as follows :
Biodegradable oils may be used if they comply with the following requirements :
• Ambient operating temperature between - 15° C (- 9° F) and + 40° C (+ 104° F)
• HEES type biodegradable oil only according to standards ISO 15380 and VDMA 24568
• Necessary characteristics :
